Organic removal in S3, sewage, first the sewage after step S2 processes is pumped in biological rotating disk, again the disc of biological rotating disk about 40% is partially immersed in sewage, then disc is made to rotate, disc alternately contact sewage and air, cultivate through after a while, the biomembrane of microorganism composition can be attached with on disc, the organic pollution in microorganism panning sewage on biomembrane, as nutrition, generates carbon dioxide and water, it is achieved that organic removal in sewage after reaction；Ammoniacal nitrogen in sewage is converted into nitrate in biological rotating disk, with in mixed-liquor return to regulating reservoir；
S4, through step S3 process after sewage by biological rotating disk gravity flow enter sedimentation tank, the mud in sewage is piled up in bucket under self gravitation effect, and mud flows into again sludge concentration tank, it is achieved that mud-water separation；
In S5, sewage, float and phosphorus are removed further, sewage after step S4 processes is entered filtering cloth filtering pool by sedimentation tank gravity flow, in sewage, appropriate Dephosphorization reagent is added through dephosphorization agent adding set before being passed through filtering cloth filtering pool, after Dephosphorization reagent and sewage carry out coagulating, the carrying out flowed in filtering cloth filtering pool is filtered, it is achieved that float and the removal of phosphorus in sewage；
S6, sewage self-flowing after step S5 processes enter in manpower rapid-infiltration pond, the nitrogen phosphorus in sewage is absorbed further by the vegetation in manpower rapid-infiltration pond, in gravity flow enters tubular type ultraviolet sterilizer subsequently, killing the pathogenic bacteria etc. in sewage by tubular type ultraviolet sterilizer to the ultraviolet of pipeline internal radiation, the clear water reaching discharge standard after process is drained in irrigation canals and ditches through tubular type ultraviolet sterilizer.
Described step S4 is positioned at the sludge settling of sludge concentration tank bottom pond, and supernatant gravity flow enters in regulating reservoir.
The invention have the advantages that Organic substance that the present invention can effectively remove in sewage, nitrate, phosphorus, silt etc., technique has advanced reliable, reduced investment, and operational management is convenient, rationally distributed, the feature of high treating effect.
