Abstract
The utility model discloses a device for removing heavy metal ion in waste water, and a purpose of removing the heavy metal ion is obtained by the waste water contained with the heavy metal ion being passed through a regulating reservoir, a reaction tower, a precipitation separation device, a filter, etc. The utility model has the advantages of compact structure, few investment, low operation cost, convenient operation and reliable performance. The utility model can be extensively used for the treatment of the waste water contained with the heavy metal ion.
Description
The utility model is about the environment protection device, more detail is to remove various harmful heavy metal ionic devices in the waste water.
Processing at plating, non-ferrous metal, in the pickling of Iron And Steel Industry, all contain waste water such as chromium, copper, zinc, lead, cadmium, nickel to a nature discharging part, severe contamination environment, cause public hazards,, thin film evaporation is arranged at present in order to solve this type of pollution, devices such as the exchange of reverse osmosis membrane ion exchange resin, electrolysis, ferrite, chemical reduction, absorption are handled the waste water that contains heavy metal ion.Though said apparatus has certain effect to removing heavy metal ion, yet in actual motion, prove said apparatus, at aspects such as management, energy consumption, investment, working cost, maintenance capacity, land seizure areas, undesirable part is respectively arranged, and the adaptability of the height of the kind of the heavy metal ion that contains in the waste water and concentration is all had certain limitation.
Present inventors are because the deficiency of said apparatus, find can remove the heavy metal ion in the waste water at four layers of reaction tower a certain amount of scrap metal of packing into, have so far finished the utility model.
The purpose of this utility model is to make a kind of heavy metal ion in the waste water to be removed effective, less investment, convenient management, simple to operate, is suitable for especially that to contain the heavy metal ion kind in the waste water many, the device that contained change in concentration is big.
In order to achieve the above object, the utility model is achieved in that
The acid waste water that contains heavy metal ion, through equalizing tank (1), pass through reaction tower (6) from bottom to top by water pump (2), mixing tank (7) is transferred PH, after making waste water after the processing part (10) is filtered after filtration, coagulation part (8) swash plate (9) precipitation discharged or the recycling waste residue discharges through slag-drip opening (12), in reaction tower (6), there is three layers every layer scrap metal is housed, adorns Wingdale or rhombspar, quartz sand is housed for the 4th layer at filtration fraction (10).
Employed scrap metal is a pig scrap in the utility model.
Reaction tower (6) is considered protection against corrosion employing Vybak.
Employed water pump in the utility model, valve is corrosion resistant.

For the utility model is described better, below conjunction with figs. describe the utility model in detail:
The waste water that at first contains heavy metal ion, concentrate at the dirty equalizing tank of collection (1), use noncorrosive pump (2) waste water to be evacuated to the reaction tower (6) that contains pig scrap then, waste water after treatment adds medicament and transfers its aqueous ph value, medicament and waste water are mixed, and the coagulation part is filtered then through swash plate (9) precipitation, waste residue is through mummification discharging or reclaim wherein precious metal again, and waste water discharges after filtering or recycles.
