5)Aeration and sedimentation:Sewage after being handled through fine fack is passed through in aerated precipitation tank again, and is passed through air capacity 2.0-
4.0m3/min;
6)Sterilization:Sewage after aeration and sedimentation is carried out disinfection processing, detect it is qualified after discharge.
Preferably, the step 1)The grid of the middle coarse rack used is 60-90mm, and the grid of fine fack is 5-6mm;
Preferably, the step 1)Coarse grid, the refined net of middle use use curved structure, the sewage solids now intercepted
And floating object.
Preferably, described step 3)The amount of middle addition aluminium polychloride and polyacrylic acid amide, is that every ten thousand tons of sewage gather
Close 7-8 tons of aluminium chloride, 7-8 kilograms of polyacrylic acid amide.Pollution of this formula for being to water body is minimum, and can effectively reduce
The cost of processing.
Preferably, described step 2), step 5)Produced precipitating sludge is concentrated, and the sludge after concentration is carried out again
Landfill or burning disposal, can effectively realize twice laid.
The invention provides a kind of modified technique of sewage recycling, by blocking grid, precipitation, chemical treatment, logical thin
Grid, aeration and sedimentation, sterilization, can effectively remove a large amount of wastes present in sewage, and do not greatly reduce in sewage
The harm of the chemical toxic substances of presence.The handling process that the present invention is provided, can carry out large-scale application popularization, and single treatment
Amount is big.
