Description
Technical field
The invention belongs to technical field of waste water processing, more particularly to a kind of heavy metal containing wastewater treatment agent.
Background technology
Waste water (wastewater) refers to the general name of the water discharged in resident's active procedure and runoff rainwater, and it includes life
Sewage, industrial wastewater and first rain footpath flow into other useless water such as sewer.It is various with the fast development of China's chemical industry
New chemical products are applied to all trades and professions, particularly in the heavily contaminated industry such as medicine, chemical industry, plating, printing and dyeing.Industry Waste
Water flows directly into channel, rivers, lake pollution surface water, if toxicity causes the dead or even exhausted of aquatic animals and plants compared with conference
Mark, industrial wastewater are also possible to penetrate into underground water, polluted underground water.If nearby residents use contaminated surface water or underground
Water can endanger health, severe one is dead as domestic water.Industrial wastewater penetrates into soil, causes soil pollution, influences plant
With the growth of Soil Microorganism.Some industrial wastewaters also carry unpleasant stench, pollute air.Poisonous in industrial wastewater has
Evil material can be remained in vivo by ingesting for animals and plants with absorption, then reached by food chain in human body, human body is made
Into harm.Also with the problem of environmental pollution of getting worse while product quality, quality is improved, it is mainly manifested in：Waste water
Middle organic pollution concentration height, Stability Analysis of Structures, biochemical are poor, and common process is difficult to qualified discharge, and processing cost is high, gives
Industry energy conservation emission reduction brings great pressure, and this is the problem of numerous domestic environmental worker and administrative department's concern, and life is used
Water treatment problems are also one of a great problem of wastewater treatment now.
Find that China nearly has 60% in the Chinese land resources publication of issue in 2012 from the Ministry of Land and Resources in China
Groundwater quality is poor, and in all Water-quality Monitoring Points in the whole nation, the water quality for having 17% is excessively poor, and heavy metal pollution is tight
The provinces and cities of weight just reach as many as 14.When heavy metal is adsorbed by organism, in addition to single ion is present, it is also possible to biology
Internal protein, amino acid, aliphatic acid, carboxylic acid and phosphoric acid combines, and forms acylate, inorganic acid salt and chelate.Weight
The toxicity of metal ion and its compound, typically by and the combination of living organism composition play a role, with organism
The more strong then toxicity of combination is stronger.There is minamata disease and Itai-itai diseases in Japan from the 1950s, and investigate this be by
After the nuisance disease caused by mercury pollution and cadmium pollution, the problem of environmental pollution of heavy metal receives much attention.Mesh
Before, the most interestingly pollution of lead, mercury, cadmium, arsenic and chromium etc..And the heavy metal substance in waste water how is efficiently removed, no
The technique of complexity and special equipment are needed, is a research emphasis.
The content of the invention
The technical problems to be solved by the invention are to provide heavy metal containing wastewater treatment agent, and it efficiently can be removed in waste water
