Description
Technical field
The present invention relates to a kind of sewage metal cation segregation apparatus.
Background technology
Water is the material base that the mankind depend on for existence and development, maintains the progress of entire society.Point out according to the United Nations's a report recently, be in the medium or tense situation that highly supplies water more than the area of 1/5 population in the world.Water resources in china total amount occupies the 6th, the world. but the water yield is about the 1/4 of world's water yield per capita per capita, is one of the country of water resource wretched insufficiency, it is contemplated that by 2010, total breach was up to 114,000,000,000 t [1].Developing recently as commercial production and Level of Urban Modernization. waste water discharges in a large number, and Accumulation of heavy metals aggravation in water source, heavy metal pollution is serious, and therefore the improvement of heavy metal wastewater thereby is subject to the great attention of domestic and international researcher.
Heavy metal wastewater thereby cheats internal drainage, mill tailings draining essentially from mine, and waste-rock yard drenches immersion, non-ferrous metals smelting works' dedusting draining, Non-ferrous Metals Processing Factory's acid washing water. the industrial wastewaters such as Electroplate Factory's plating piece washings, steel plant's pickling draining, and electrolysis, pesticide, medicine, paint, pigment.In recent years, along with the increase of industrial development and mankind itself's activity.A large amount of industrial wastewaters containing heavy metal contaminants and city domestic sewage are drained into rivers and lakes.
It is long that heavy metal wastewater thereby pollution has toxic effect.Biological nondegradable feature, can pass through food chain effect and enter human body, and accumulate in human body.Thus causing various disease and disorder.Finally health is caused serious harm.Wherein major metal polluter has Cu, Zn, Hg, Ni, Cd, Pb and Cr etc.." minamata disease " that Japan's Minamata bay is caused by mercurialism, " itai-itai " that magic basin, river is caused by cadmium, it is simply that heavy metal pollution brings the typical example of infringement to health.Visible, the improvement of heavy metal-containing waste water is very urgent.Traditional heavy metal sewage treatment device use cost is higher, and treatment effect is bad, it is impossible to meets the requirement of modern people, is therefore badly in need of the technology of a kind of improvement to solve above-mentioned technological deficiency.
Summary of the invention
