Abstract
The invention relates to a method for deep treatment and reuse treatment of steelworks waste water. The method comprises the following steps: introducing sewage raw water to an adjusting tank with a volume of 3000 cu.m; utilizing a lifting water pump to lift the raw water in the adjusting tank to a pre-coagulation tank and performing the coagulation reaction by adding 5-10 kg of lime, 0.5-1 kg/cu.m of coagulant and 1-5 kg/cu.m of coagulant aid; discharging treatment water having undergone the coagulation reaction into a high-density clarification tank and performing pre-settling concentration inclined tube separation; discharging separated reaction water into a post coagulation reaction tank and performing the coagulation reaction again by adding 1-5 kg of lime; discharging the treatment water having undergone the coagulation reaction again into a V-shaped filter tank and filtering the treatment water; and discharging the filtered treatment water into a clear water pump house. The method is good in reuse treatment effect and low in cost.
Description
Technical field
The present invention relates to a kind of waste water reuse treatment method, be specifically related to a kind of steel plant wastewater process for reclaiming.
Background technology
China is the country that water resources is abundant, but due to distribution of water resources uneven, it is serious to add waste, and causing China is the serious country of drought and water shortage.Water is valuable resource, and therefore, all trades and professions are enterprise especially, how to accomplish that water resources reuses, has become extremely urgent problem.
Iron and steel enterprise uses water rich and influential family in industrial enterprise, and consume new water index for reducing ton steel, each iron and steel enterprise is all devoted to collection and treatment and a mouthful waste water is always arranged in reuse, it can be used as main reduction mode.Existing waste water recycling method efficiency is low, and input cost is higher, and line service amount is large, and need staff regularly to watch, the occasion higher at ask for something is inapplicable, and work-ing life is not long, does not meet actual operation requirements.
Summary of the invention
Goal of the invention: the object of the invention is to overcome deficiency of the prior art, provide a kind of Treatment for Reuse effective, cost is low, and routine maintenance amount is little, long service life, the steel plant wastewater advanced treatment and reclamation treatment process of realistic service requirements.
Technical scheme: in order to solve the problems of the technologies described above, a kind of steel plant wastewater advanced treatment and reclamation treatment process of the present invention, it comprises the following steps:
(1) former for sewage water is introduced equalizing tank, equalizing tank volume is 3000m
3;
(2) lifting water pump is utilized the former water extraction in equalizing tank to be raised to front coagulation basin, by adding 5-10kg lime, 0.5-1kg/m
3coagulating agent and 1-5kg/m
3coagulant aids, carries out coagulating;
(3) the process water after coagulating is entered high dense settling pond, carry out preliminary sedimentation and concentrate inclined tube separation;
(4) reaction water after separation being entered rear coagulation reaction tank, by adding 1-5kg lime, again carrying out coagulating;
(5) the process water after coagulating is again entered V-type filter tank, filter;
(6) the process water after filtration is entered clean water pump room.
Described coagulating agent is aluminium iron polychloride.
Clear water in described clean water pump room is passed into V-type filter tank, carries out back flushing.
The overflow water of described front coagulation basin and the backwashing wastewater in V-type filter tank are entered equalizing tank.
Mud bottom described high dense settling pond is entered between sludge dewatering, carries out sludge condensation and dehydration.
Air blast machine room is connected to bottom described V-type filter tank, carries out back flushing air blast.
Beneficial effect: compared with prior art, its remarkable advantage is: the present invention is easy to operate in the present invention, and each step closely cooperates, and Treatment for Reuse is effective, and cost is low, long service life, realistic service requirements.
