Abstract

The invention relates to a sludge circulating filtration integrated reactor and a sewage treatment method, and belongs to the technical field of sewage treatment. The integrated reactor comprises a box body, and an aerobic activated sludge area, a sludge circulating filtration area and a water outlet area are sequentially arranged in the box body from left to right; when sewage treatment is carried out, sewage flows through the sludge circulating filtration integrated reactor from left to right. The reactor has the advantages that the high activated sludge concentration (up to 4500-5000 mg/L)can be maintained, effluent is clean after sludge filtration, and the treated water quantity meets the primary A standard of the discharge standard of pollutants for municipal wastewater treatment plant (GB 18918-2002). Through hydraulic circulation, continuous updating of a sludge layer is kept, and interception of microorganisms and clarification and filtration of water are completed, so that the bioreactor has the advantages of being high in biomass retention, small in equipment size and efficient in mud-water separation.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated reactor for sludge circulation and filtration and a method for sewage treatment. Background technique [0002] The domestic sewage produced by towns and villages contains organic matter and nitrogen and phosphorus pollutants. If not properly disposed of, it will pollute the receiving water body. In order to improve the water environment quality of urban residents, the government requires urban and village sewage to meet the first-class A standard of the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB 18918-2002). As far as the current use of domestic sewage treatment processes in our country is concerned, the AAO synchronous denitrification and phosphorus removal process that continuously flows into the water is the main one. [0003] Pollutants in domestic sewage mainly include organic matter (often represented by chemica...
