Rural Inner Mongolia wastewater treatment equipment process principle and the importance of equipment structure composition: Today's life is constantly changing every day. Today, Xiaobian still brings you knowledge about wastewater treatment. Today is about new rural small sewage Water treatment equipment process principle. The new rural small-scale sewage treatment equipment adopts the A / O process principle and is optimized. It has the function of continuous water inflow and out at constant water level. The treatment effect is good, the operation is stable, unattended, and it can flexibly treat various types of domestic sewage. It is a modular high-efficiency sewage biological treatment equipment. The sewage biological treatment system with biofilm as the main body of purification takes full advantage of the high biological density and pollution resistance of biofilm reactors such as anaerobic biological filters and contact oxidation beds. Strong, low power consumption, stable operation and convenient maintenance. The new rural small-scale sewage treatment equipment adopts FRP, carbon steel, and stainless steel anticorrosive structures. It has excellent characteristics such as corrosion resistance and aging resistance. It has a long service life, greatly extending the service life and reducing the use cost.
Small-scale sewage treatment equipment can be placed above or below the ground, saving land use, no need to build a house, heating and insulation. To a large extent, the integration of equipment is achieved, and the footprint is reduced. The new rural small sewage treatment equipment system is equipped with a fully automatic electrical control system and equipment failure alarm system. The rural sewage treatment equipment is cheap and operates safely and reliably. Inner Mongolia sewage treatment small sewage treatment equipment can effectively treat rural and urban domestic sewage, industrial wastewater, etc., to prevent sewage and pollutants from flowing directly into the waters, which is of great significance to improve the ecological environment, upgrade urban quality and promote economic development. The structure of small-scale rural sewage treatment equipment mainly consists of seven parts: 1. Grille: Before entering the equipment, the sewage enters the adjustment tank to adjust the water quality and quantity of the sewage. The effective retention time of the adjustment tank is generally 4-8 hours to intercept the sewage. Large particles of debris ensure the normal operation of the pump. A grille is set at the inlet of the adjustment tank. The grille is made of 304 stainless steel, which has the advantages of not easy to block, good separation effect and long service life. 2. Biological contact oxidation pond: It is divided into two levels, with a total biochemical time of 10 hours. The biological contact oxidation pond in Inner Mongolia wastewater treatment equipment uses BOB type biological combined packing, which has a large specific surface area. The biochemical pond uses a membrane of the center corridor. Aeration or jet aeration, the sewage continuously circulates in the biochemical tank, and fully contacts the biofilm on the filler to achieve rapid degradation of organic matter. 3. Anoxic tank: Anoxic tank is set up for denitrification treatment. The sewage separated by the grid enters the anoxic tank through the sewage pump, and the sludge in the sludge tank also returns to the anoxic tank. The phosphorus and sulfide removal effect is good. The company's special BOA-type biological filler is placed in the anoxic tank as a carrier of denitrifying bacteria, and the residence time is 2 hours. It is combined with the biological contact oxidation tank in the subsequent process to form the A / O process. So as to achieve the purpose of dephosphorization and denitrification.
4. Secondary sedimentation tank: The biochemical sewage enters the secondary sedimentation tank. The design surface load of the secondary sedimentation tank is 1.0m3 / ㎡.hr. The secondary sedimentation tank adopts inclined tube sedimentation, which has high sedimentation efficiency and large sedimentation area, which is larger than traditional vertical flow sedimentation. The efficiency of the pond is 3-5 times higher. The side-drilled water collecting tank has a good water outlet effect. The drainage of the water collecting tank is uniform and stable. The gravity of the sludge from the secondary sedimentation tank enters the sludge tank by gravity. 5. Sterilization tank: The standard retention time of the disinfection tank is 30 minutes. If it is hospital sewage, the disinfection time can be increased by 1-1.5 hours. The disinfectant uses the commercial sodium hypochlorite solution. The special disinfection device is usually added once every 10 days, according to the amount of water. The size is constantly changing the dosage. 6. Sludge tank: The sludge tank collects the sludge produced by the sedimentation tank, and some sludge is returned to the anoxic tank by the sludge pump for anaerobic digestion; excess sludge only needs to be discharged once every 90 days or more. 7. Modular fan room for wastewater treatment in Inner Mongolia : The fan room for small sewage treatment equipment in rural areas is set up separately, and two rotary fans are installed inside, which can be alternately operated automatically. The automatic control cabinet, air-lifting and sludge controller are integrated with the fan room. The fan runs 50,000 hours without failure, and has a beautiful appearance. Well, that's all. The above are the knowledge points mentioned by the editor. The editor brought about the new rural small sewage treatment equipment process principle. Everyone will find it useful after reading it. Very happy For Inner Mongolia wastewater treatment equipment, everyone has wood and feels very useful. If you like Xiaobian, please follow this website quickly.
