Background technique
In recent years, with the rapid development of China's economic, pollution of waterhead is got worse, and drinking water source water quality is gradually reduced.
Heavy metal wherein in sewage is extremely serious to water pollution.The heavy metal processing method in sewage mainly has three classes at present：The
The method that one kind is heavy metal ions in wastewater to be removed by the way that chemical reaction occurs, including neutralization precipitation method, sulphide precipitation,
Ferrite coprecipitation, chemical reduction method, electrochemical reducing and high molecular heavy metals trapping agent method etc..Second class is to make waste water
In the heavy metal method being adsorbed, be concentrated under conditions of not changing its chemical form, separated, including absorption, solvent extraction
It takes, evaporate and freezing method, ion exchange and UF membrane etc..Third class be by the flocculation of microorganism or plant, absorption, accumulation,
The method that the effects of enrichment removes heavy metal in waste water, including bioflocculation, biochemical process and plant ecological reparation etc..
But existing adsorbent treatment effect is undesirable, be easy to cause secondary pollution, increases the place of sewage heavy metal
Manage cost.
Summary of the invention
The technical problems to be solved by the invention are in view of the above shortcomings of the prior art, to provide a kind of for going to decontaminate
The compound adsorbent of heavy metal in water.
