污水处理工艺图（Sewage treatment process diagram） F99 Sewage treatment process flow chart Sewage into the plant by intercepting wells (sewage entering the plant to plant can handle processing) into coarse grid (salvage large garbage) to sewage pump (sewage lifting height) to the fine grid (small fishing scum) to the settling basin (based on gravity separation, the inorganic particles larger proportion of sewage precipitation and biochemical pool (excluding) to the use of activated sludge removal in BOD5, SS and the various forms of nitrogen or phosphorus) into the final sedimentation tank (excluding sludge and sludge) into the D type filter (further reduce SS, with water up to the national standard in ultraviolet disinfection (kill the water) Escherichia coli) and water A part of the sludge produced by the biochemical tank and the final settling tank is used as the return sludge of the biochemical tank, and the remaining is sent into the sludge dewatering to be transported out of the sludge The main physical treatment method, biological treatment method and chemical treatment method, biological treatment method is often used, the mainstream processing method mainly depends on water quality and treatment are receiving water, city sewage treatment is generally the mainstream method for biochemical treatment method, such as activated sludge, MBR method. sewage disposal Sewage treatment.wastewater treatment measures certain standards that are set in order to treat the sewage after a certain process. Some measures or methods for discharging into the water body, discharging into a water body or re using it, etc. Modern wastewater treatment techniques are classified according to the degree of processing. They can be divided into one level, grade two and stage three Primary treatment. The removal of sewage is solid pollutants in suspension. Most can only complete a request processing. After a physical treatment of wastewater treatment.BOD can remove about 30%. Reach the discharge s
