Customized processing of wastewater treatment equipment for food factories——Design Principles

1Adopting advanced composite bioreactor sewage treatment technology to ensure that all indicators of the treated effluent meet the discharge requirements.

2The sewage from the sewage treatment plant is the comprehensive discharge water for daily life. The discharged sewage must be pre treated and meet the inlet requirements of the sewage treatment plant before it can be included in the sewage discharge system.

3Wastewater treatment plants are easy to operate, manage, and maintain equipment while reducing their impact on the surrounding environment.

4Wastewater treatment facilities have great flexibility and adjustability in operation to adapt to changes in water quality and quantity, while striving for small footprint, low engineering investment, low operating energy consumption, and low treatment costs.

5When designing, full consideration should be given to the prevention and control of secondary pollution in sewage treatment plants, and corresponding measures should be taken for deodorization, noise reduction, and vibration reduction of supporting equipment. The small amount of residual sludge generated during the sewage treatment process should be regularly cleaned and transported by external units after aerobic digestion treatment to avoid secondary pollution to the environment.

6The sewage treatment system is equipped with emergency bypass and dual power protection measures.

7The sewage treatment power equipment and other supporting equipment are all selected from well-known domestic manufacturers to ensure stable, stable, and reliable operation.

Customized processing of wastewater treatment equipment for food factories——The role of accessories for integrated sewage treatment equipment

1.The function of the integrated sewage treatment equipment grid well is to remove suspended solids in the wastewater.Impurity isolation can avoid affecting the later processing of equipment.
2.The function of regulating pool: The time period of water discharge is uneven according to the characteristics of domestic water use, and their discharge time is basically set early.Chinese.The late three time periods are peak periods, and uneven water supply can be adjusted for later processing to ensure normal operation. A water level controller is installed in this regulating pool to effectively implement automation control.
3.The function of the integrated sewage treatment equipment anaerobic tank: sewage flows into the anaerobic tank and is fully combined with anaerobic bacteria through the stirring effect of the mixer. Anaerobic tanks can decompose microorganisms and organic matter in wastewater, producingCO2Substances such as methane.
4.The function of anoxic tank: The water from the anaerobic tank flows into the anoxic tank to further decompose organic matter and remove ammonia from the wastewater.nitrogen.Phosphorus removal: The clear liquid from the upper layer of the anoxic tank flows into the contact oxidation tank, while the sludge enters the anaerobic tank through the reflux pipe to increase the concentration and improve the treatment efficiency of the anaerobic tank. When the concentration of the anaerobic tank is saturated, the reflux valve is closed and the valve flowing to the sludge concentration tank is opened, allowing the sludge to directly flow into the sludge concentration tank.
5.The function of the contact oxidation tank: When the water from the anaerobic tank flows into the sewage in the contact oxidation tank and comes into contact with oxygen
After the oxidizing bacteria (three-dimensional elastic packing) in the chemical pool come into full contact, the sewage decomposes intoCO2.H2OBy the action of a blower, the waterCO2Discharge. The composition of sludge is the dead bodies of bacteria.
6.The second sedimentation tank of the integrated sewage treatment equipment allows the water in the contact oxidation tank to undergo secondary sedimentation. The settled water flows into the disinfection tank, while the sludge is pumped to the sludge concentration tank through a sludge pump. The water in the disinfection tank is treated by a chlorine dioxide generator to meet the standard before being discharged. After sedimentation in the sludge concentration tank, the supernatant is returned to the regulating tank through a reflux pipe, and the sludge is pumped to the plate and frame filter press for treatment. The filtered water flows through the reflux pipe to the regulating tank

Customized processing of wastewater treatment equipment for food factories——Principle Description

Wastewater flows into the solid-liquid separation chamber, where solid substances in the water are separated and stored; Forcing the intermediate water between the upper floating slag and the bottom solid matter in the solid-liquid separation chamber to overflow to the anoxic filter bed filled with packing, for the removal of solid matter, decomposition of organic matter, and denitrification of nitric acid and nitrous acid; Afterwards, it flows into the carrier flow chamber, and under the action of a large amount of biofilm attached to the surface of the carrier filled with several millimeters to centimeters, the organic matter in the sewage is further decomposed into nitrification, and the nitrification liquid flows back to the solid-liquid separation chamber. The treated water flows into the biological filtration chamber through a grid at the transfer section to prevent the loss of carriers. The carriers accumulated at the bottom are filtered from top to bottom to remove themSSSuspended solids. The backwashing of the biological filtration room is carried out twice a day by a small blower（2Combination of tables or with dual outlets for air dispersion and backwashing1Automatic completion of the task. The backwash water containing suspended solids washed off is sent back to the solid-liquid separation chamber through an air stripping device. The effluent from the bottom of the biological filtration room is sent to the disinfection room for disinfection through a measuring device by steam extraction and then discharged. The remaining treated water flows back to the carrier flow chamber through the side outlet of the metering box.
The upper part of the solid-liquid separation chamber, anoxic filter bed, and carrier flow chamber is equipped with a large capacity inflow sewage storage space, namely a flow adjustment section, which plays a role in alleviating the problem of excessive flow during peak flow rates that cannot be treated temporarily. When there is no inflow, the water level in the tank drops to a low level, and the incoming water from the biological filtration chamber is circulated back through the metering tank without being discharged; When there is water inflow, the water level in the tank rises, and the incoming water from the biological filtration chamber is metered, disinfected, and discharged through the measuring box. The remaining water circulates back to the carrier flow chamber.
The entire system consists of nine parts, selectedPCLControl and then achieve automated disposal, which can also alleviate the normal disposal of water during peak and low periods. The characteristics of integrated sewage treatment equipment: the entire set of equipment can be buried underground and does not occupy land area; It can also be beautified above. High degree of purification, minimal sludge generation in the entire system; High degree of automation, low energy consumption, convenient handling, and fewer personnel involved. Low noise and less odor occur, with minimal impact on the surrounding environment.

Customized processing of wastewater treatment equipment for food factories——feature

1Wastewater treatment consists of secondary tanks, made of steel structures and buried shallowly. The steel structure pool is coated with the latest domestic interpenetrating network anti-corrosion coating for corrosion prevention. It is an interpenetrating polymer composed of a rubber network and a plastic network, which can resist acid, alkali, salt, gasoline, kerosene, aging, abrasion, and rust. After the equipment is usually coated with this paint, the anti-corrosion life can reach12Years or more.

2In sewage treatment equipmentAOThe biological treatment technology uses a push flow biological touch oxidation tank, which has better treatment than mixed or two-stage series mixed biological touch oxidation tanks. Moreover, it has a smaller volume than activated sludge tanks, strong adaptability to water quality, good impact resistance, stable effluent quality, and will not cause sludge swelling. At the same time, a new type of elastic three-dimensional packing material was selected in the biological touch oxidation tank, which has a large actual specific surface area, convenient microbial biofilm formation and detachment, and higher removal rate of organic matter than other packing materials under the same organic load conditions. It can improve the solubility of oxygen in water from the air.

3Due toAOIn biological treatment technology, a biological touch oxidation tank is selected, which has a relatively low volume load of fillers and microorganisms are in their own oxidation stage, resulting in less sludge production. In addition, the moisture content of the sludge generated by the biological touch oxidation tank is much lower than that of the sludge generated by the activated sludge tank. Therefore, the amount of sludge generated by sewage treatment equipment is relatively small, usually only requiring90Drain the mud once every day.

Customized processing of wastewater treatment equipment for food factories——How to integrate integrated sewage treatment equipment into society

1Make full use of idle funds in society. At present, on the one hand, there is a huge financial pressure to build large-scale sewage treatment plants, and on the other hand, there is a large amount of idle social funds that are difficult to utilize. The total investment in integrated equipment is very small, suitable for small social capital investments such as real estate and small factories, which can directly and effectively utilize idle funds. This is also more in line with China's environmental protection characteristic of "whoever pollutes, who controls".

2Relieve the pressure on municipal pipeline construction. The construction of large-scale sewage treatment plants often requires the construction of a large-scale municipal pipeline system. For small residential areas, scenic spots, factories and other places with underdeveloped pipeline networks, building sewage treatment plants is neither convenient for management nor economical. In this case, using integrated equipment is more suitable. In addition, for the diversion drainage system, smaller flow sewage can be directly discharged into rainwater pipes or water bodies after being treated by integrated equipment without increasing the pressure of the sewage pipes.
