Process principle of sewage treatment biochemical system

Process principle of sewage treatment biochemical system——Sewage treatment process flow and description:

Grille: The grille adopts a specially developed integrated manual grille composed of coarse and fine grids, which intercepts and removes larger suspended and floating particles in sewage, protecting subsequent treatment facilities.

Regulating tank: The water quality and quantity of the sewage in the camp area change over time. The main function of the regulating tank is to homogenize the water quality and quantity, and it also has the function of oil separation and sand settling, as well as a certain degree of hydrolysis and acidification.

Non powered ecological treatment field: Based on the principle of anaerobic biological reaction, the anaerobic biofilm non powered sewage treatment technology is proposed. It utilizes the micro anaerobic decomposition of biofilm grown on the surface of the packing material, the adsorption and filtration resistance of the filter material layer and biofilm, and the synergistic purification effect of food chain classification and predation along the water flow direction, as well as the adsorption and filtration resistance of the filter material layer and biofilm and the food chain classification and predation along the water flow direction, to efficiently decompose and remove pollutants in the sewage; The effluent directly meets the discharge standards; At the same time, utilizing the principle of endogenous respiration of microorganisms, the balance between microbial proliferation and digestion is achieved in the reactor support layer, filtration layer, reaction layer, and ultrafiltration layer, achieving zero sludge discharge.

Process principle of sewage treatment biochemical system——Characteristics of aerobic tank

Due to its advantages, it has been widely used as a popular technology in sewage treatment.

The contact oxidation tank is rectangular in shape and divided into two levels2：1The proportion division is that the first tank is a high load oxidation tank, and the second tank is a low load oxidation tank to ensure the full degradation of various forms of mainly soluble organic pollutants and the removal of ammonia nitrogen. The overall direction of water flow belongs to the push flow type, but the single pool water flow state belongs to the fully mixed type, and the aeration method belongs to the delayed aeration, so it has the advantages of the three while discarding their disadvantages.

The filling material adopts internationally advanced three-dimensional elastic filling material,The water flow conditions are extremely superior and can perform secondary cutting on bubbles,It has the advantages of hardness, softness, and semi softness. Compared with rigid honeycomb packing, this filler has a greater variability in pore size and is not clogged;Compared with soft fillers, the material has a longer lifespan and does not adhere or clump together;Compared with semi soft fillers, it has a larger specific surface area and faster film formation. Aeration is carried out through a central corridor, with an air-water ratio of15：1The sewage continuously circulates in the biochemical tank to ensure that the biofilm on the packing material fully contacts with the sewage, allowing the organic matter in the sewage to be fully degraded. The oxygenation equipment also has a variable microporous aerator, and the membrane material is imported ternary propylene rubber. The aeration tube adoptsABSEngineering plastic pipe.

Process principle of sewage treatment biochemical system——Integrated membrane bioreactor

Integrated membrane bioreactor is a sewage treatment device that integrates membrane components into a bioreactor, combining the advantages of membrane filtration and bioreactor. Its main features are:(1)Replacing the secondary sedimentation tank with membrane separation equipment for sludge water separation has comprehensive advantages in technology, management, investment, and land occupation, with less residual sludge;(2)Membrane modules are usually placed inside bioreactors without the need for sludge return equipment, which consumes much less energy than external membrane modules. They can also significantly remove bacteria and viruses, resulting in good effluent quality;(3)Perforated tubes are installed below the membrane module for aeration, creating a circulating flow rate on the membrane surface to reduce membrane surface pollution and odor generation;(4)Membrane components are prone to clogging and require cleaning and replacement, which can cause inconvenience in operation.

Process principle of sewage treatment biochemical system——Advantages:

There are various processes for sewage treatment equipment, and the outstanding advantages of meeting the effluent standards are:

1.Domestic sewage treatment equipment can be buried underground, and greening can be carried out on top for a beautiful environment.

2.Domestic sewage treatment equipment generally does not require dedicated personnel to manage the entire equipment.

3.Domestic sewage treatment equipment can reduce the footprint, and parking lots can be built above the equipment without the need for factory buildings or other facilities.

Process principle of sewage treatment biochemical system——Daily inspections and equipment maintenance
When the system is first started or shut down for a long time, it is necessary to check: Are all manual valves in the correct position.
The valve next to the outlet duct of each blower should be in the open position.
Check the oil window of the fan to ensure there is sufficient oil and lubrication.
Check if there is any leakage in the water pump pipeline and if the suction port is blocked.
Check the circuit, wiring control cabinet wiring, voltage and current to ensure they meet the requirements, and display correctly when installing the equipment.
Check whether the automatic control instruments, including water level and various equipment status indicator signals, display correctly.
Check if the grounding wire contact and electrical equipment's resistance to ground are good.
check380VIs the voltage in place and is the three-phase voltage balanced.
Close the power switch and check if the motor direction of each branch electrical equipment meets the requirements.
Check whether the working current of each electrical equipment meets the requirements of the nameplate

Process principle of sewage treatment biochemical system——Installation precautions

1The installation location of the equipment must ensure that the foundation pit should not sink or accumulate water during rain.

2The outlet pipe of the equipment must be located on the opposite floor500mmBelow,

3No heavy objects should be placed above the equipment to avoid large vehicles passing by,

4Generally, equipment should not be emptied of internal sewage to prevent groundwater from causing the equipment to float.
