Technical scheme: in order to solve the problems of the technologies described above, a kind of steel plant wastewater advanced treatment and reclamation treatment system described in the utility model, it comprises equalizing tank, front coagulation basin, high dense settling pond, rear coagulation reaction tank, V-type filter tank and clean water pump room, between them, by pipeline, be linked in sequence successively, described pipeline is all located under grade, in described V-type filter tank, have air blast machine room, at described high dense settling pond, have between sludge dewatering, in described equalizing tank one end, be provided with raw water inlet, dosing mouth before described front coagulation basin top is provided with, dosing mouth after described rear coagulation reaction tank top is provided with, in described front coagulation basin bottom, be provided with overflow water pipeline, be connected to described equalizing tank, in described high dense settling pond bottom, be provided with mud discharging pipeline, be connected between described sludge dewatering, in bottom, described V-type filter tank, be provided with backwashing wastewater pipeline, be connected to described equalizing tank.
Between described sludge dewatering, comprise sludge thickener and sludge dewatering room.
In described front coagulation basin and rear coagulation reaction tank, be provided with between dosing.
On described clean water pump room, be provided with back flushing water supply line, be connected to described V-type filter tank.
On described air blast machine room, be provided with back flushing blowing line, be connected to described V-type filter tank.
Between described equalizing tank and front coagulation basin, be provided with lifting water pump.
In the utility model, Wastewater Form Circulating Cooling Water drains into equalizing tank, and equalizing tank was by water yield design in 6 hours, and equalizing tank useful volume is 3000m
3.Equalizing tank is established lifting water pump, according to liquid level, control the start and stop that promote water pump, rise to highly dense pond dosing coagulating, and adopt mechanical dosing to flocculate, carry out the concentrated inclined tube of preliminary sedimentation separated, water outlet is entered rear coagulation basin again from flowing to the water outlet up to standard of V-type filter, and clean water basin are established in water outlet, and clean water basin useful volume is for being greater than 1000m
3.Precipitating sludge is partly refluxed to coagulation reaction tank, and excess sludge is to sludge thickener, concentrated after mud through the belt filter press dry mud outward transport of dewatering, dehydration filtrate and V-type filter tank backwash water are returned equalizing tank.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: each parts of the utility model are closely connected, compact construction, adopt between equalizing tank, front coagulation basin, high dense settling pond, rear coagulation reaction tank, V-type filter tank, clean water pump room, air blast machine room, sludge dewatering and between dosing, practical function is integrated, and equipment anti-shock ability is strong, running cost is low, easy to operate, long service life, realistic service requirements.
