Description

A kind of heavy metal wastewater thereby fast purification processing system

Technical field

The utility model relates to technical field of waste water processing more particularly to a kind of heavy metal wastewater thereby fast purification processing systems System.

Background technique

Heavy metal wastewater thereby refers to that is be discharged in the industrial processes such as mining and metallurgy, machine-building, chemical industry, electronics, instrument contains weight The waste water of metal is environmental pollution most serious and endangers one of maximum industrial wastewater, water quality and quantity and production to the mankind Technique is related, and the heavy metal in waste water cannot generally decompose destruction, can only shift it there are position and change its Material Form.It is useless Water process is exactly to be handled using the method for physics, chemistry and biology waste water, makes purification of waste water, reduces pollution, so that reach To Sewage treatment, multiplexing, water resource is made full use of；With the fast development of modern industry, all kinds of waste water are largely discharged, many institute's weeks Know, contents of many kinds of heavy metal ion, such as lead, zinc, mercury, cadmium, chromium contained in industrial wastewater, be discharged into it is very harmful in water environment so that Heavy metal pollution of water body is serious, is not only difficult to be biodegradable, and biological chain can be also entered by water body, is finally enriched to human body It is interior, human health is seriously endangered, on the other hand, demand of the modern society to heavy metal is increasing, and heavy metal resources occur Therefore the situation of relative shortage realizes the high-efficient purification processing of heavy metal wastewater thereby, recycling heavy metal becomes current heavy metal wastewater thereby Handle urgent problem to be solved.

When carrying out wastewater treatment, flocculation is an essential step；Flocculation is to instigate microactuator suspension in water or liquid Grain, which gathers, becomes larger or is formed floc sedimentation, to accelerate the coagulation of particle, achievees the purpose that solid- liquid separation, this phenomenon or operation claim It flocculates.Usually flocculated to implement by adding flocculant appropriate, effect is adsorbent particles, between particle " bridge formation ", thus Promotion is gathered, and in the process, the mixability of flocculant and waste water is very crucial, and mixability is higher, then flocculating effect It is better, it in order to obtain more preferably flocculating effect, then needs adequately to stir waste water with flocculant, by waste water with flocculation It after agent mixing, is usually passed into flocculation basin and settles, to realize the separation of flocculation group and water, reach wastewater treatment purification Effect.

Sewage treatment equipment in the prior art, though it can be realized to processing and purification containing effluent containing heavy metal ions, But for the present inventor in practice, it has been found that it more has following defects that 1, do not have Wastewater Pretreatment function, what is contained in waste water removes weight Other impurities particle outside metal ion can impact subsequent purification process；2, generally use agitating paddle realize waste water with The stirring efficiency of the mixing of flocculant, agitating paddle is low, and mixing effect is limited, and the mixed effect of waste water and flocculant is bad；3, The mixing apparatus of waste water and flocculant does not have self-clean function, waste water is formed with flocculant in blending tank suspended particulates or just Step flocculation group easily attaches on tank skin, and gets deeper, and is used for a long time, will affect mixed effect of the waste water with flocculant, equipment Service life substantially reduces；3, in such a way that flocculation basin carries out sedimentation separation, flocculation basin is taken up a large area, low separation efficiency, Separating effect is unobvious, increases the processing time of waste water；4, the addition of flocculant still relies upon manually to carry out, not only waste compared with More human resources, and the additive amount of flocculant is difficult to control accurately；5, it is not easy to heavy metal ion flocculation group after realization separates Recycling.
