A kind of polymeric flocculant of the present invention is handled the method for sewage/wastewater, and its step is as follows:
Sewage/wastewater is introduced grating tank, remove bigger foreign material and floating matter after, enter water collecting basin, the silt particle that proportion is bigger in the sewage is fallen at the bottom of the pond, enter equalizing tank again and compile, regulate water quality, the water yield, be that next procedure keeps the stable water quality and the water yield;
Start sump pump with in the sewage suction reaction tank in the equalizing tank, and press the polymeric flocculant that sump pump discharge capacity hourly adds 0.15-1.5 ‰, start the stirrer that is contained on the reaction tank simultaneously and stir, the add-on of flocculation agent is determined with different trade effluent water quality according to sanitary sewage.Add the radically reform polymer QH flocculation agent of environment protection treating Engineering Co., Ltd development of Chongqing, this flocculation agent is to extract macromolecular compound from plant, by grafting, draw hydroxyl, amido, carboxymethyl etc., be mixed with inorganics is compound again, add the electrostatic double layer that can compress the pollutent colloidal particle in the sewage rapidly, the formation net of building bridge is simultaneously caught, and fast pollutants in sewage is condensed into the bigger flock of density, rely on the action of gravity natural subsidence, remove pollutants in sewage.
Sewage enters settling tank after flocculation treatment, rely on action of gravity to fall Yu Chidi naturally, realizes solid-liquid separation, removes pollutent;
Enter the filter-sterilized pond through the supernatant liquor of post precipitation from the top of settling tank, the fine suspension Filtration Adsorption with residual enters clean water basin again;
From clean water basin, take a sample and detect, reach emission standard, can discharge or recycle.
Described a kind of polymeric flocculant is handled the method for sewage/wastewater, and is further comprising the steps of:
Mud is got rid of: respectively the mud of equalizing tank, settling tank bottom is evacuated to sludge thickener with sludge pump.
Mud concentrates: in sludge thickener, carries out, and from mud natural subsidence the pond that extract out equalizing tank, settling tank bottom, supernatant liquor flow automatically back equalizing tank, processing once more.
Sludge press filtration: with dewatering on the mud suction pressure filter of sludge pump with the sludge thickener bottom, the water that removes returns in the equalizing tank, handles once more.
Adopt present method to handle sewage/wastewater, speed of response is fast, technology is simple, and the treatment time is short, phosphor-removing effect is remarkable especially, can reach emission standard after the sewage disposal, and the mud of generation do not expand, nontoxic, can make the plant fertilizers for potted flowers.Be applicable to and handle various trade effluents and city domestic sewage.
