Description
Technical field
The present invention relates to a kind for the treatment of process of oil-containing heavy metal industrial effluent, belong to the field of waste water treatment in environment protection.
Background technology
Heavy metal contamination refers to the environmental pollution and ecological damage that are caused by heavy metal and compound thereof, and its hazard rating depends on the concentration that heavy metal exists in environment, food and organism and chemical form.Heavy metal contamination is mainly manifested in water pollutions, and some is in air and solid waste.Heavy metal contamination is different from the pollution of other organic compound, and many organic compound can be purified by the physics of nature itself, chemistry or biological effect, hazardness is reduced or eliminates; And heavy metal has enriching, be difficult to degrade in the environment.
From the viewpoint of environmental pollution, heavy metal contamination most is representational is mercury, cadmium, lead and " metalloid "---the significant heavy metal of the bio-toxicities such as arsenic, these heavy metals can not be decomposed in water surrounding, the mankind drink rear toxicity and amplify, and other toxin in water are combined and can generate the larger organic compound of toxicity.
At present, existing trade effluent heavy metal treatment process comprises: chemical precipitation method, electrolytic process, absorption method, membrane separation process, ion exchange method etc.
