Structural description of complete sewage treatment equipment:

1. Mechanical grille:

After being collected by the production wastewater management network system, it enters the subsequent treatment system after passing through a coarse grid. Coarse grid is mainly used to intercept large floating objects in sewage, ensuring the normal operation of subsequent treatment structures and effectively reducing treatment loads, providing guarantees for the long-term normal operation of the system.

2. Sewage regulating tank:

Used to regulate water volume and ensure uniform water quality, so that sewage can enter the subsequent treatment unit more evenly. Setting up a pre aeration system in the regulating tank can improve the impact resistance of the entire system, reduce the foul odor of sewage in anaerobic conditions, and reduce the design scale of subsequent treatment units. Submersible sewage pumps are installed in the sewage tank to lift and send sewage to the subsequent treatment units.

3. Hypoxia pool:

Elastic packing is installed in the anoxic tank to intercept fine suspended solids in wastewater and remove some organic matter. The nitrification solution after reflux in the anoxic tank is subjected to denitrification and denitrification, which improves the removal rate of ammonia nitrogen in wastewater. The sewage treated with hypoxia enters the aerobic biological treatment tank.

4. Contact oxidation tank:

Most of the organic matter in the original sewage is degraded and purified here. Aerobic bacteria use fillers as carriers and utilize the organic matter in the sewage as food to decompose it into inorganic salts, thereby achieving the purpose of purification. The survival of aerobic bacteria requires sufficient oxygen, that is, there is enough dissolved oxygen in sewage to achieve the purpose of biochemical treatment. The air in the aerobic tank is provided by a fan, and a new type of semi soft biological packing material is used in the tank. The packing material has a large surface area ratio, long service life, easy film formation, and corrosion resistance. The bottom of the tank is equipped with a microporous aerator, which increases the transfer rate of dissolved oxygen. At the same time, it has the advantages of light weight, non aging, non clogging, and long service life. Contact the two major components inside the oxidation tank:

Packing: This process uses a new type of three-dimensional elastic packing, a layer dense high-efficiency biochemical packing, which has the advantages of large specific surface area, long service life, easy film formation, and corrosion resistance. At the same time, the filler has a certain degree of stiffness and can cut the bubbles in the sewage at multiple levels, increasing the efficiency of dissolved oxygen. In addition, the fillers are not easily agglomerated, avoiding blockage of the oxidation tank. Aerator: This process uses a microporous aerator, which has a higher dissolved oxygen transfer rate than other aerators. Its biggest feature is that it does not age, is lightweight, has a long service life, and has advantages such as corrosion resistance and resistance to clogging.

5. Sedimentation tank:

After being treated in a biological contact oxidation tank, the wastewater flows automatically into a secondary sedimentation tank to further precipitate and remove detached biofilms and some organic and inorganic small particles. The sedimentation tank is based on the principle of gravity. When the wastewater containing suspended solids flows from bottom to top, the substances are precipitated by gravity. The effluent after sedimentation in the secondary sedimentation tank is clearer and more transparent. The secondary sedimentation tank is a vertical flow sedimentation tank, which uses a sludge pump to regularly lift sludge and gas into the sludge digestion tank. The treated water after sedimentation enters the subsequent treatment equipment.

6. Disinfection pool

After sedimentation, the virus and Escherichia coli indicators in the sewage still do not meet the discharge standards. In order to eliminate the virus and Escherichia coli, chlorine tablet disinfectant is added for disinfection treatment. The folded plate form is used to rely on its own gravity and directly discharge into nearby municipal pipelines.

7. Sludge digestion tank:

The remaining sludge discharged from the sedimentation tank is subjected to aerobic digestion and stabilization treatment in the tank to reduce the volume of sludge and improve its stability. The amount of sludge after aerobic digestion is relatively small. Regular contact should be made with the environmental sanitation department to remove and transport the sludge by suction truck or to carry out sludge dewatering treatment for external transportation. The supernatant is refluxed to the regulating tank.

8. Fan:

Used for gas supply to contact oxidation tanks, pre aeration of regulating tanks, and aerobic digestion treatment of sludge digestion tanks.

Process description of complete slaughter wastewater treatment equipment:

This project adopts the biofilm method: anaerobic aerobic (A/0) treatment process. A/O, also known as anaerobic+aerobic biological contact oxidation, is a mature biological treatment process that has the advantages of high volumetric load, fast biodegradation rate, small footprint, low infrastructure investment and operating costs. It can replace the ordinary activated sludge method used in urban sewage treatment and is particularly suitable for the treatment of medium and high concentration industrial wastewater, with low investment, small footprint, and high treatment efficiency. This process adopts a combination of biological contact oxidation and precipitation, and is mature and reliable. Sludge is precipitated in the equipment, and a portion of the sludge is further oxidized and decomposed due to the action of dissolved oxygen, while another portion is lifted into the sedimentation tank. The system sludge only needs to be regularly pumped in the sedimentation tank. The working program of the main control equipment such as the wind turbine and submersible sewage pump in the system is input into the PLC machine to achieve automatic operation, reduce the workload of operation, and minimize unnecessary human damage.
