Description of the sewage treatment process This project uses the biofilm method: anoxic----aerobic (A/0) treatment process. A/O, hypoxia + aerobic biological contact oxidation is a mature biological treatment process, which has the advantages of high volumetric load, fast biodegradation, small floor space, low capital investment and low operating cost. The common activated sludge method used in urban sewage treatment is especially suitable for the treatment of medium and high concentration industrial wastewater, and the investment is low, the land occupation is small, and the treatment efficiency is high. The process adopts a combination of biological contact oxidation and precipitation, and the process is mature and reliable. The sludge is precipitated in the equipment, and part of the sludge is further oxidized and decomposed by the action of dissolved oxygen, and a part of the gas is extracted into the sedimentation tank of the grit. The system sludge only needs to be pumped regularly in the grit sedimentation tank. In the system, the working procedures of the main control equipment such as fans and submersible sewage pumps are input into the PLC machine to achieve automatic operation to reduce the workload and reduce unnecessary man-made damage. 1, grille: The discharged sewage is collected by the pipe network system and then passed through the coarse grid to the subsequent treatment system. The coarse grid is mainly used to intercept large floating objects in the sewage to ensure the normal operation of the subsequent treatment structures and effectively reduce the processing load, and provide guarantee for the long-term normal operation of the system. 2. Sewage adjustment tank: It is used to adjust the water volume and uniform water quality, so that the sewage can be more evenly entered into the subsequent processing unit. The pre-aeration system is installed in the adjustment tank to improve the impact resistance of the whole system, reduce the foul odor of the sewage under anaerobic conditions, and reduce the design scale of the subsequent treatment unit. The sewage pump is provided with a submersible sewage pump for Sewage is sent to the subsequent processing unit. 3. Anoxic pool: An elastic filler is provided in the anoxic tank for intercepting fine suspended matter in the sewage and removing a part of the organic matter. The nitrification solution after the reflux of the anoxic tank is denitrified and denitrified, thereby improving the removal rate of ammonia nitrogen in the sewage. The sewage treated by the anoxic treatment enters the aerobic biological treatment tank. 4. Contact oxidation pool: Most of the organic matter in the raw sewage is degraded and purified here. The aerobic bacteria uses the filler as the carrier, and uses the organic matter in the sewage as the food material to decompose the organic matter in the sewage into inorganic salts, thereby purifying the purpose. The survival of aerobic bacteria must have sufficient oxygen, that is, there is enough dissolved oxygen in the sewage to achieve the purpose of biochemical treatment. The aerobic pool air is provided by a fan. The tank adopts a new semi-soft bio-filler. The filler has a large surface area ratio, long service life, easy to hang membrane, corrosion resistance, and a microporous aerator at the bottom of the tank to make the transfer rate of dissolved oxygen high. At the same time, it has the advantages of light weight, no aging, no clogging, and long service life. Contact two large accessories in the oxidation tank: Filler: This process uses a new type of three-dimensional elastic filler, layer-intensive and high-efficiency biochemical filler. The filler has the advantages of large specific surface area, long service life, easy to hang film and corrosion resistance. At the same time, the filler has a certain rigidity, can cut the bubbles in the sewage in multiple layers, so that the dissolved oxygen efficiency is increased, and then the filler and the filler are not easy to agglomerate, and the clogging of the oxidation pool is avoided. Aerator: This process uses a microporous aerator, which has a higher dissolved oxygen transfer rate than other aerators. The characteristic of Zui is that it is not aging, light weight, long service life, and has the advantages of corrosion resistance and non-clogging. 5. Sedimentation tank: After the sewage is treated by the biological contact oxidation pond, the effluent flows into the secondary sedimentation tank to further precipitate and remove the shed biofilm and some organic and inorganic small particles. The sedimentation tank is based on the principle of gravity, when the sewage containing suspended matter flows from the bottom to the bottom When flowing up, the material is precipitated by gravity. The effluent after precipitation in the secondary settling tank is more clear and transparent. The secondary sedimentation tank is a vertical flow sedimentation tank, and the sludge pump is used to periodically lift the mud to the sludge digestion tank. The treated water after the precipitation enters the subsequent processing equipment. 6, disinfection pool After the sewage is precipitated, the virus and E. coli indicators still reach the discharge standard. In order to eliminate the virus and E. coli, a chlorine tablet disinfectant is added for disinfection treatment, and the municipal pipe is directly discharged by using the gravity in the form of a folding plate. 7. Sludge digestion tank: The excess sludge discharged from the sedimentation tank is subjected to aerobic digestion and stabilization treatment in the tank to reduce the volume of the sludge and improve the stability of the sludge. The amount of sludge after aerobic digestion is small, and it is regularly removed by the dredging truck of the sanitation department or transported by sludge dewatering. The supernatant was refluxed to the conditioning cell using the supernatant. 8, the fan: It is used for contact gas supply in oxidation pond, pre-aeration of regulating tank and aerobic digestion treatment of sludge digesting tank. Second, the introduction of integrated sewage treatment equipment 1. The sewage treatment consists of a secondary tank with a steel structure and a shallow depth. The steel structure pool adopts the domestic first interpenetrating network anticorrosive coating for anticorrosion. It is a rubber network and a plastic network interpenetrating to form an interpenetrating network polymer, which can withstand acid, alkali, salt, gasoline, kerosene, aging, and abrasion resistance, and can bring rust and rust. After the equipment is generally painted, the anti-corrosion life can reach more than 12 years. 2. The AO biological treatment process in the sewage treatment equipment adopts the push-flow biological contact oxidation tank, and its treatment is better than the complete mixed or the second- or third-stage series fully mixed biological contact oxidation tank. Moreover, it is smaller than the activated sludge tank, has strong adaptability to water quality, good impact resistance, stable effluent quality, and no sludge expansion. At the same time, a new elastic three-dimensional filler is used in the biological contact oxidation tank, which has a large specific surface area, and is convenient for microbial hanging and stripping. Under the same organic load condition, the removal rate of organic matter is higher than other fillers, and the air can be improved. The solubility of oxygen in water. 3. Since the biological contact oxidation tank is used in the AO biological treatment process, the volume load of the filler is relatively low, and the microorganism is in the self-oxidation stage, so the amount of sludge production is small. In addition, the moisture content of the sludge produced by the biological contact oxidation pond is much lower than the moisture content of the sludge produced by the activated sludge tank. Therefore, the amount of sludge generated by the sewage after the sewage treatment equipment is small, and it is generally only necessary to discharge the mud once every 90 days. 4. In addition to the conventional blower silencer (such as vibration isolation pad), the integrated sewage treatment equipment is also equipped with a new sound absorbing material on the inner wall of the blower room, so that the noise during operation of the equipment is less than 50 decibels, reducing the surrounding area. Environmental impact. 5, FRP integrated sewage treatment equipment supporting automatic electrical control system and equipment damage alarm system, equipment reliability is good. 6. The integrated sewage treatment equipment can be buried below the surface of the earth. The surface can be used as a greening or plaza land. Therefore, the equipment does not occupy the surface area, does not need to be built, and does not need heating and insulation.
