Technical field
The invention belongs to technical field of waste water processing, and in particular to a kind of inorganic agent and its system of the waste water containing heavy metal
Preparation Method.
Background technology
Heavy metal wastewater thereby produces greatly harm to health and ecological environment.Develop heavy metal containing wastewater treatment technology,
Environmental protection is not only contributed to, and industrial development and the progress of human society can be promoted.Heavy metal wastewater thereby is mainly derived from
Mining, ore dressing, smelting, plating, chemical industry, process hides and paper industry, leaded, mercury, cadmium, chromium, nickel, copper, zinc caused by these industries
Deng heavy metal waste water be discharged into natural water body after, not only aquatile is constituted a threat to, and may be by precipitating, adsorbing and eat
Thing chain and be constantly enriched with, destroy ecological environment, and finally jeopardize the health of the mankind.When heavy metal is adsorbed by organism, remove
Single ion exists outer, it is also possible to is combined with the protein in organism, amino acid, aliphatic acid, carboxylic acid and phosphoric acid, formation
Acylate, inorganic acid salt and chelate.The toxicity of heavy metal ion and its compound, typically by with living organism into
Point with reference to and play a role, it is stronger with the more strong then toxicity of organism combination.There is water in Japan from the 1950s
Yu diseases and Itai-itai diseases, and investigate after this is due to mercury pollution and nuisance disease caused by cadmium pollution, the environment of heavy metal is dirty
Dye problem receives much attention.At present, the most interestingly pollution of lead, mercury, cadmium, arsenic and chromium etc..Therefore, find
A kind of cheap, effective inorganic agent for reducing heavy metal in waste water concentration is our urgent problems.
