The described chemical reaction stage uses throws in flocculant and medicament in urban duct；
The impurity that the chemical reaction stage is formed is precipitated accumulation by the described secondary precipitation stage further；
Sewage after secondary precipitation phase process is carried out precipitation process by described filtration stage, removes filtering residue, gets rid of filtrate；
The described biological respinse stage, for further purifying filter liquor.
Preferably, described precipitate phase is provided with every sieved filter screen in urban duct.
Preferably, the sandy gravel stratum of described precipitate phase is evenly distributed with fine sand layer, wood fibre layer, active carbon layer, pottery disintegrating slag layer, solid-state tiny in abundant absorption effluent, flocculence Impurity Impurity composition.
Preferably, the medicament used in the described chemical reaction stage is: ferric chloride, sodium sulfate, concentrated hydrochloric acid, aluminum sulfate are formed by the weight portion of 4:2:2:1.
Preferably, after described filtering residue carries out decomposing or calcining, recycling.
Preferably, the described biological respinse stage, first filtrate is flowed through solid packing, filtrate can generate the biomembrane of sludge-like on filler, biomembrane can grow substantial amounts of microorganism, is conducive to removing a large amount of microorganisms present in filtrate further, then flows to process further in the pasture and water pool, can be processed by pasture and water further, the harmful components in purifying filter liquor.
The invention provides a kind of new city conduit wastewater processing method, by operating procedure, successively sewage is entered precipitate phase, chemical reaction stage, secondary precipitation stage, filtration stage and biological respinse stage.First precipitate, solid-state in sewage, flocculence impurity component can be greatly reduced；In the after chemical reaction stage, substantial amounts of ionic state metal impurities is made to form solid, being easy to the secondary precipitation stage is removed, the last biological respinse stage, in the removal carrying out tiny microorganism, whole flow process cost is relatively low, can carry out further genralrlization application in present urbanization sewage conduct construction.
