Sewage treatment works Technology (1) artificial biological purification artificial biological purification, is artificially creating conditions for microbes multiply, domesticated microbe, using the method of microbial metabolic degradation of organic compounds in water quality is today at home and abroad for secondary treatment of sewage soil processes. The main advantages are: sewage treatment effect is stable, you can adjust the processing efficiency of sewage processor within a certain range, the treatment process, felled and small size. The main disadvantages are: high investment, high operating costs, management complexity, the need to operate more staff. The main treatment process is as follows: a sewage sedimentation (or flotation) a biofilm a biofilter (rotating biological contact oxidation, activated sludge) an aeration tank (oxidation ditch) sedimentation (or flotation) a disinfection an outlet (2) natural biological purification of natural biological purification process, the main use of pollutant concentration in soil microorganisms and plant roots or pond of microorganisms so that the water is reduced. The main advantages are: low investment (land acquisition costs 10,000 yuan / hm case), low operating costs, simple to manage, less operators needed. Sewage may be used alone offer, but also with each other to form a coalition deal with the system. Disadvantages are: large-felled area. The main treatment process is as follows: a precipitate a sewage lagoon (land treatment) a rapid infiltration (full speed infiltration, overland flow) sewage treatment process of sewage treatment station equipment two enhanced treatment: 1, two enhanced treatment process It is defined in the effective removal of carbon contamination outside sewage integration equipment, processing technology and have a strong function of phosphorus and nitrogen removal. 2, nitrogen and phosphorus pollutants control requirements of the region, the daily processing capacity of more than one hundred thousand cubic meters of sewage treatment facilities, generally used by A / O, A / A / O method and other techniques, can also be a prudent use other The same efficient technology. 3, the daily processing capacity of one hundred thousand cubic meters of sewage treatment facilities, in addition to use of A / O, external A / A / O method can also be used with a phosphorus and nitrogen removal effect of oxidation ditch, good ABR, hydrolysis oxygen and biological filter method. 4, if necessary, can also be used to strengthen the physical and chemical phosphorus removal method.
