Domestic wastewater treatment plant | Yulin domestic wastewater treatment | Luoyang Luoyang Yu Quan Yu Quan environmental protection provided by the sewage treatment Limited. Luoyang Yu Quan Sewage Treatment Co., Ltd. (www.yuquankj.net) is a professional engaged in "environmental protection equipment, sewage treatment equipment, industrial wastewater treatment equipment, grille decontamination machine" of the company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to participate in healthy competition in the market, so that the "Yu Quan, YQ" brand has a good reputation. We adhere to the "service first, customers first" principle, so Luoyang Yu Quan Environmental won the trust of customers in the public sewage treatment equipment, and establish a good corporate image. Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! That soil irrigated land treatment method method is the earliest human use of sewage treatment, but the application of land treatment system common in urban sewage treatment. For leachate treatment of domestic wastewater treatment plant, the leachate collected, returned to the landfill through sprinklers to make it. Landfill leachate due to increased recycling garbage humidity, thereby increasing the biological activity, accelerate methane production and waste decomposition. Secondly, due to the evaporation of the sprinkler, so that leachate volume decreases, the operation is conducive to the wastewater treatment system, and can save energy costs. North of England Seamer Carr landfill leachate recirculation using part, COD value 20 months after leachate recirculation zone is reduced more, the metal concentration has decreased substantially, and NH3 -N, Cl- concentration small changes. Description decreased metal concentration is not only due to the dilution effect caused by the waste may also be caused by inorganic components of its adsorption. Because leachate recirculation has many advantages, so the design of the landfill at the top do not all closed, but should establish regular arrangement of the channel in order to avoid contamination of the surrounding water. Low concentrations of leachate can not be discharged directly, because NH3-N, Cl- concentration is still high, the temperature is low season, less evaporation domestic wastewater treatment pond, the biological activity of weak domestic wastewater treatment, leachate recirculation effect needs further study. Several comparative process sewage treatment systems: the process in order to select the most reliable investment most economical and convenient management of urban sewage treatment systems, combined with the actual local conditions, we investigated the mature experience in wastewater treatment plant and trends, and compared. At present, domestic and municipal sewage treatment plant processes mostly using a treatment and secondary treatment. A treatment is the use of physical methods, mainly through the grille blocking, precipitation and other means to remove suspended solids in wastewater chunks and sand and other substances. The treatment process at home and abroad are mature, not very different. Secondary treatment is the use of chemical and biological methods for sewage treatment equipment, mainly by means of microbial life movement, etc. Removal of suspension, dissolved organic matter and nitrogen, phosphorus and other nutrients. Currently, the treatment process has a variety of methods, summed up the main representative of the conventional activated sludge process, oxidation ditch, A / O or A2 / O process, SBR and CCAS crafts. Currently, there are several representatives of the practical application of technology at home and abroad.
