Technical field
The utility model relates to urbanite water consumption equipment technical field, relates in particular to a kind of heavy metal contamination ground water cleaning water supply installation.
Background technology
Heavy metal-pollutedly have a finger in every pie the environmental pollution being caused by heavy metal or its compound.Heavy metal has very strong hazardness, and its hazard rating depends on concentration and the chemical form that heavy metal exists in environment, food and organism.Heavy metal contamination is mainly manifested in water pollution, and some is in atmosphere and solid waste.
Heavy metal contamination is different from the pollution of other organic compound.Many organic compound can, by the physics of nature own, chemistry or biological purification, reduce hazardous property or remove.And heavy metal has enriching, be difficult to degrade in environment.At present China is due in the exploitation at heavy metal, smelting, the course of processing, causes many heavy metals to cause serious environmental pollution as lead, mercury, cadmium, cobalt etc. enter atmosphere, water, soil.Heavy metal as discharged with useless heavy metal mercury water even if concentration is little, also can accumulate in algae and bed mud, by fish and shellfish body surface, is adsorbed, and produces food chain concentrated, thus the public hazards of causing.Favourable or harmful kind, the physico-chemical property that not only depends on metal of metal in water body, but also depend on the concentration of metal and the valence state of existence and form, even if useful metallic element concentration surpasses a certain numerical value, also have violent toxicity, make animals and plants poisoning, even dead.Organometallics (as organic mercury, organic lead, organoarsenic, organotin etc.) is more much better than than corresponding metal inorganic compound toxicity; The metal of soluble state is larger etc. than the toxicity of particulate form metal again.
Due to mining and smelting all the year round, Chinese heavy metal contamination event happens occasionally.In recent years, in succession there is the children blood lead event that exceeds standard in Anhui, Shaanxi, zhejiang and other places.In January in this year, part section, river, Longjiang, Guangxi occurs that cadmium pollution exceeds standard, and the mineral water event of buying is robbed by Liuzhou City, downstream.Planning refers to, heavy metal contamination all causes serious threat to ecotope and public health.Recently, the section, Longjiang more than the power station, glutinous rice beach, Liucheng County of 57 kilometers of upstreams, urban district, Liuzhou, the water bodys that still have cadmium concentration to exceed standard more than 5 times reach 100 kilometers.This heavy metal water pollutes, and causes in many ways and pays close attention to.
Therefore, how to realize and the water source in heavy metal contamination region is purified to drink be current important problem urgently to be resolved hurrily.
