Background technology
Current, environment, resource, population become the three big subject matters that the world faces, the deterioration degree of global environment and day sharp increase, and the survival and development to human society cause serious threat.Production produces a large amount of wastes in will making the process that resource changes product into, form the primary pollution source of production to environment.Because production has a large capacity and a wide range, thereby very big to the general impacts of environment.We can say that production is the mainstay industry of creation of mankind wealth on the one hand, but be again the main source of environmental pollution simultaneously.
Along with electronics, plating, wiring board, household electrical appliances are disassembled the development disorder of industry, heavy metal contamination is serious day by day, and the burst Pollution incident increases year by year, China's soil, river, agriculture prodn and people's health is caused very big harm.In want urgent solution problem is listed heavy metal contamination by government.
Heavy metal contamination has persistence, diffustivity, enriching characteristics:
(1) persistence: it is nondegradable, can in soil, have hundreds and thousands of years.
(2) diffustivity: it can be along with surface water, Groundwater Flow and by local diffusion to wider scope.
(3) enriching: no matter in the water or the heavy metal in the soil, all can finally get into human body, cause lasting harm to human health along food chain to the high-end enrichment of biologic chain.
The chemical method wastewater processing technology of existing extensive employing can make the heavy metal in the waste water handle first discharge standard, and technology maturation.But its investment is big, running cost is high, the pond structures many and can't move, and the more important thing is, drop into a large amount of number of chemical raw materials.Though heavy metal is up to standard in the water body, water body inorganic salt and sludge quantity have raise at double, are the transfer of pollutent in essence.
Both at home and abroad to the improvement of mixture-metal waste water, the technology that extensively adopts is a chemical method at present, has had decades historical, technology maturation, and heavy metal removing rate is higher.But in service in reality, three obstacles are but arranged:
