Biological Aerated Filter Technology West City Subdivision Wastewater Treatment Plant In Daqing City

BAF (Biological Aerated Filter) referred to as BAF, is the late 80's in Europe and the United States developed a new type of biofilm wastewater treatment processes. The process has to remove SS, COD, BOD, nitrification, denitrification, phosphorus removal, removal of AOX (hazardous substances) role, which is characterized by sets of biological oxidation and retention of suspended solids and one follow-up to save the sedimentation tank (secondary sedimentation pool), the volume load, hydraulic loading, and hydraulic retention time is short, less the required investment in infrastructure, good water quality: the low energy consumption, operating costs the province.Biological Aerated Filter (biologicalaeratedfilter) and conventional activated sludge method, with a high organic load, small footprint, does not produce sludge bulking, oxygen transfer efficiency, the advantages of good water quality.Daqing City as an oil-based fast-growing emerging industrial city in northern China, if the urban sewage can not be effectively dealt with, which is downstream of Daqing City, the city itself and the environment will cause a great impact, it can not compete with the growing to improve the standard of living of the people to adapt, but also a serious obstacle to the city of Daqing urban development and economic construction.At present, all the Xicheng District of untreated sewage discharged directly into the bubble, ditch, creek water, severe pollution of rivers, resulting in water colors, pungent odor, as well as natural water pollution not only affects the urban environment, pollution the shallow groundwater near the source; At the same time, the quality of irrigation is very much affected, to the public health cause great harm. Xicheng District, the final of the natural water body into the Songhua River, Daqing is the urban section of the Songhua River in Harbin, the upper reaches of the Songhua River in Harbin City is the main water source, so, in order to lower reaches of the people can drink clean water, urban construction in the West sewage treatment plant is very urgent!...
