Description
Technical field
The present invention relates to field of waste water treatment, in particular to the heavy metal wastewater thereby reaction tank of artificial swamp.
Background technique
Heavy metal pollution is mainly derived from two aspects of mankind's activity and Spontaneous release.It shows according to the study, Pb, Zn and Cu
Content in sewage is them respectively 30,40 and 15 times of average content in crustal rock.Spontaneous release mainly includes certainly
Right weathering Erosion and colcanism etc., in general not will cause water body by the heavy metal that natural way enters in water environment
Pollution, but cause plurality of heavy metal pollutant to enter in water environment due to mankind's activity, not only can be in water environment
Animals and plants generate direct harm, more can all generate serious adverse effect to human health and the entire ecological balance, cause
The economy and Ecological Loss that can not be estimated.It is heavy metal-polluted caused by mankind's activity recently as the continuous development of human industry
Dye has become main aspect.Heavy metal wastewater thereby is greatly mostly from the row such as plating, chemical industry, electrolysis, mining, steel, nonferrous smelting
Industry such as mine hole internal drainage, electroplate factory's plating piece washing water, non-ferrous metals smelting works' dedusting draining, waste-rock yard leaching immersion, has coloured gold
Belong to processing factory and steel plant's acid washing water, mill tailings draining, and the industrial water drainages such as medicine, pigment, paint, electrolysis, pesticide.
Its heavy metal type, existing forms and content are different and different because the industry of discharge heavy metal and production technology, and difference is more
Significantly.Such as Cr, Cd, Hg are mainly from plastics industry；Zn, Ti, Sn etc. are mainly from textile industry；Ni, Cd, Zn, Sb mainly come
From microelectronics industry.As metallic weapon is widely used, this also to contain a certain amount of Zn, Cu in city domestic sewage
Equal heavy metals, and there are the pollutants such as suspended matter, the heavy metal largely generated by traffic activity in the rainfall runoff in city, this
Water environment can all be damaged a bit.Often there is handling, water is small, at high cost, energy consumption is high, is applicable in for traditional treatment process
Range is small, easily causes the deficiencies of secondary pollution, and the process cycle of biological treatment is too long and not easy to control.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of heavy metal wastewater thereby reaction tank of artificial swamp, in waste water
