general narrate, recount, state

Futian, Boluo County***The metal products factory is located inHuizhou, Guangdong ProvincecityLuangang Management Area, Shiwan Town, mainlyOperating electroplating of copper, nickel, and chromiumCyanideWait.The electroplating wastewater generated during the pre-treatment and coating process of workpieces, if directly discharged, will pollute the water and soil environment, and have a certain impact on people's living environment. So the company's wastewater must be treated with priority.

The company's leadership attaches great importance to environmental protection and has invested in the construction and operation of a wastewater treatment project.With the increasingly serious problem of heavy metal pollution in China in recent years, relevant departments in some regions have formulated measures to address itA series of regulations and requirements have been made for the discharge of similar water pollutants, resulting in the need to upgrade and rectify the sewage treatment system of the plant,Ensure that wastewater meets discharge standards.

On behalf of the owner, our company's relevant personnel consulted with relevant technical personnel from the factory and, based on understanding and mastering the production equipment configuration of the workshop and the use of the existing sewage treatment supporting system, made the following rectification measures for the wastewater treatment:

1.1 Wastewater treatment measures

The original sewage treatment system operates stably and has a good effect on removing copper, nickel, chromium, cyanide, etc., and also meets relevant discharge standards. However, some processes have not met current requirements, such as independent treatment of pollutants such as copper, nickel, chromium, cyanide, etc. But other pollutants such asCOD did not meet the new emission standards. Based on the above situation, for the treatment of a type of pollutant, pipeline renovation should be carried out in the existing sewage system. For COD treatment in comprehensive wastewater, thenAdopting a biochemical treatment method that is cost-effective in terms of facility investment and operation costs.According to the current production situation, the water treatment capacity of various types of wastewater is detailed in the following table:

serial number	Wastewater type	Wastewater volume (m)3/d）	Running time (h)	Design processing capacity (m)3/h）	remark
1	Nickel containing wastewater	16	16	1
2	Chromium containing wastewater	56	16	3.5
3	Copper containing wastewater	16	16	1
4	Cyanide containing wastewater	56	16	3.5
5	Acid alkali wastewater	64	16	4
	total	208	16	13

1.2 Current situation analysis

1The process flow of the original sewage treatment system is as follows::

Cyanide containing wastewaterCyanide containing regulating tank, first level cyanide breaking, second level cyanide breaking

Chromium containing wastewaterChromium containing regulating tank chromium breaking reaction

Nickel containing wastewater

Copper containing wastewater comprehensive regulating tank

Acid alkali wastewater

2Each reaction tank for raw sewage treatment is equipped with an automatic dosing system.

3Some sewage has not been classified and collected.

1.3 Rectification ideas

Taking into account the investment cost, ease of operation, and easy maintenance, the following suggestions are suggested:

① According to the requirements of relevant departments, Class I pollutants must be treated separately to meet the standards before being combined with other wastewater for treatment. Namely, separate the cyanide containing wastewater, chromium containing wastewater, nickel containing wastewater, and copper containing wastewater before merging them into the acid-base wastewater regulating tank.

② Based on the removal of pollutants (mainly COD) in this projectProcess selectionMore maturereliableThe operating costs are relatively economicalHydrolysis acidification+MBR process;

③Place the newly added sewage treatment system facilities on the open space next to the original sewage treatment system.

④The rectified process flow is as follows:

Cyanide containing wastewaterCyanide containing regulating tank, first level cyanide breaking, second level cyanide breaking

Chromium containing wastewaterChromium containing regulating tank chromium breaking reaction

Analysis of Processing Technology Route3.2.1 Pollutant Analysis and Treatment Selection

• Regarding the main pollutants in the wastewater of this project:1. Suspended solids (SS); 2. Ammonia nitrogen; 3 COD； 4 BOD； Now analyze and select the processing technology item by item:

Suspended solids（SS）：

• Containing a certain amount of

COD， After separating large impurities with a sieve or grid, coagulation and sedimentation can be carried out with a removal rate of over 90%.Ammonia nitrogen:Should be in₂A/O biochemical treatment or SBR activated sludge process for nitrification and denitrification treatment,

• The final product is N

Remove by blowing off.

• COD：

If the COD concentration is high, the "hydrolysis acidification+MBR" method should be used for removal. Although the wastewater concentration in this project is low, the discharge standard is high. Choosing MBR treatment is more appropriate because MBR management is convenient and simple, and the effluent is stable.

BOD：

The use of aeration biological treatment method has good results. As long as a certain amount of air is supplied, the organic matter in the wastewater, as nutrients for microorganisms, will be continuously adsorbed, oxidized, decomposed, and separated by precipitation, thus achieving continuous aerobic treatment. There are usually the following methods.3.2.2 Selection of Wastewater Treatment SchemeThe wastewater in this project has been pre treated and its water quality is better than that of ordinary wastewater, with only a small portion of pollutants not meeting the discharge requirementsCOD, BOD, etc. This plan adopts hydrolysis acidification+MBR method to remove COD and BOD from the wastewater.Biochemical treatment

lawDue to mature technology, low operating costs, and simple operation and management, it has become the core of current industrial wastewater treatment processes. The use of biological treatment methods has good effects. As long as a certain amount of air is supplied, the organic matter in the wastewater, as nutrients for microorganisms, will be continuously adsorbed, oxidized, decomposed, and separated by precipitation, thus achieving the goal of continuously removing pollutants.

IBiochemical treatmentWhenThe content of organic pollutants in wastewater is very high, and it is difficult to meet the standard by using only primary biochemical treatment. Therefore, the design of the biochemical system adopts hydrolysis acidification+secondary aerobic treatment,

• Adopt advanced

MBR method is used to ensure that the effluent meets the discharge standards.hydrolytic acidification

Anaerobic biochemical treatment of wastewater is a complex biochemical process that relies on the combined action of three major groups of bacteria to complete the complex anaerobic biochemical process. This complete process can be roughly divided into

• Three consecutive stages, namely hydrolysis and acidification stage, hydrogen production and acetic acid production stage, and methane production stage.
• Hydrolysis and acidification are two processes controlled throughout the anaerobic process (acidification may not be very efficient). The use of hydrolysis tanks has the following advantages over anaerobic tanks (digestion tanks) throughout the entire process.
• Under the action of extracellular enzymes from hydrolytic bacteria, insoluble organic matter is hydrolyzed into soluble substances. With the synergistic action of acid producing bacteria, large molecular substances and difficult to degrade substances are converted into small molecular substances that are easy to biodegrade. Therefore, hydrolysis tanks can change the biodegradability of raw wastewater, thereby reducing reaction time and treatment energy consumption.
• The degradation of solid organic matter can reduce the amount of sludge, and its function is the same as that of a digestion tank. The process only produces a small amount of biologically active sludge that is difficult to anaerobically degrade, thus achieving one-time treatment of sewage and sludge without the need for a frequently heated medium temperature digestion tank.
• No need for a sealed pool, no need for a three-phase separator of water, gas, and solid, reducing costs and facilitating maintenance. Due to these characteristics, structures suitable for large, medium, and small sewage treatment plants can be designed.

2The reaction is controlled until the second stage is completed, and the effluent has no adverse odor of anaerobic fermentation, improving the environment of the treatment plant.Fully utilizing the short generation cycle and rapid reaction of acid producing bacteria through hydrolysis, the hydrolysis tank has a small volume, comparable to the initial sedimentation tank, saving infrastructure investment.

TheMBR

MBR0.4The working principle of membrane bioreactor process: Firstly, biodegradable organic pollutants in water are removed by activated sludge, and then the purified water and activated sludge are subjected to solid-liquid separation using a membrane.The membrane used in this project is a hollow fiber membrane with a pore size ofM

mLeft and right, it can retain activated sludge and the vast majority of suspended solids, achieving clear effluent. In order to ensure the continuous and long-term stable use of the membrane, a certain intensity of air is continuously shaken under the hollow fiber membrane, which not only provides oxygen for biological oxidation but also prevents activated sludge from adhering to the surface of the membrane and causing membrane pollution. For example:

（1) High strength of the membrane:

Due to the preparation method of polypropylene hollow fiber membrane usingThe film making method of "melt extrusion and stretching molding" uses polypropylene macromolecules with regular orientation, resulting in high strength of the film. During high-intensity aeration and regular chemical cleaning processes, the film is not easily broken.

（

2) The chemical stability of the membrane is good:During the production process of polypropylene hollow fiber membranes, no additives or pore forming agents are added, resulting in good chemical stability. Strong acid or strong alkali cleaning can be used. Chlorine containing disinfectants can be used for cleaning to remove a large amount of microbial contamination from the membrane surface. The flow recovery after chemical cleaning is good.（

3）Schematic diagram of membrane（4）Hollow fiber membraneis suitable for

YuOne of the membrane materials used in MBR technology is mainly based on the following performance characteristics:

• MBR

The advantages of the process are as follows:Convenient operation and managementThe traditional aerobic activated sludge treatment process may experience sludge expansion when operating under high sludge loads, making it difficult to separate the sludge and resulting in the system not functioning properly and the effluent not meeting standards. ButMBRThe process uses membrane suction for sludge water separation, and sludge expansion does not affect it

• MBR

The normal operation and effluent quality of the system make operation and management extremely convenient.3000compact footprintThe concentration of activated sludge in traditional activated sludge processes is generally around～5000mg/lBut8000MBRThe concentration of activated sludge in the process is generally～12000mg/lAnd there is no need for a biochemical sedimentation tank, which greatly reduces the land occupation and civil engineering investment. Its civil engineering land occupation is about the same as that of traditional processes

• 1/3

.

• Stable treatment of water quality

Hollow fiber membranes can intercept almost all microorganisms, especially those that are difficult to precipitate and have slow growth rates. Therefore, the biological phase in the system is greatly enriched, and the process of domestication and increment of activated sludge is greatly shortened. The depth of treatment and the system's ability to resist impact are strengthened, and the treated water quality is stable.Has excellent denitrification effect

• MBR

The system is conducive to the interception, growth, and reproduction of slowly proliferating nitrifying bacteria, and the nitrification efficiency of the system is improved.

• Long mud age

Membrane separation allows large molecules in wastewater that are difficult to degrade to have sufficient residence time in a limited volume bioreactor, greatly improving the degradation efficiency of recalcitrant organic matter. The reactor operates under high volume load, low sludge load, and long sludge age, and can achieve almost no residual sludge discharge.0.1Low power consumption0.4The required suction pressure for hollow fiber membranes is only -～－²kilogram

Left and right, low power consumption.

Membrane bioreactors are easy to integrate, achieve automatic control, and have convenient operation and management;

• 3.4 Process Description：
• Wastewater containing cyanide, chromium, nickel, and copper is separately treated in independent reaction tanks and then combined in sedimentation tanks3. Conduct mud water separation, and the supernatant flows into the acid-base comprehensive regulation tank by itself. After being pumped by the lift pump to the coagulation tank for sufficient reaction, it flows into sedimentation tank 1 and sedimentation tank 2 in sequence. The supernatant uniformly flows into the newly added hydrolysis acidification tank by itself.High molecular weight and complex organic compounds in sewage are decomposed by anaerobic or facultative bacteria into low molecular weight and easily biodegradable organic compounds, such as organic acids. Then it flows in automatically
• MBRPerform aerobic treatment on the pool.MBRBiological treatment process is a new type of wastewater treatment process that combines membrane separation technology with biological treatment technology. The microorganisms in the activated sludge in the reactor, under the condition of continuous oxygenation in the aeration tube of the tank, use organic matter and dissolved oxygen in the water as a nutrient source, and through their own metabolism, decompose the organic matter into simple carbohydrates（CO2TheH2O）So as to degrade the organic matter in the sewage. At the same time, the reactor is equipped with membrane components with efficient interception function, which can intercept the activated sludge and large molecular organic matter in the biochemical reaction process in the reactor, achieving solid-liquid separation in the reactor. Therefore, the concentration of activated sludge in the reactor will gradually increase, and the microbial activity will be greatly improved, which is very conducive to the degradation of organic pollutants. At the same time, the separation and separate control of hydraulic retention time and sludge retention time are achieved.MBR

A self-priming centrifugal clean water pump is installed in the membrane bioreactor system, which creates a negative pressure state inside the membrane through the water pump's suction. External sewage is intercepted outside the membrane components by the pressure difference inside and outside the membrane and the efficient interception effect of the membrane components. Clean water smoothly enters the membrane cavity through the membrane pores and is lifted by the self-priming pump, Enter the clean water tank to achieve the purpose of solid-liquid separation and wastewater treatment.
