Description

A kind of sewage flocculant

Technical field

The present invention relates to technical field of sewage, especially a kind of sewage flocculant.

Background technology

Flocculation agent is mainly divided into inorganic flocculating agent, organic polymer coargulator and microbial flocculant.Wherein inorganic flocculating agent accounts for important share on the market that China is current, has the demand of tens0000 tons every year, and mainly with molysite, aluminium salt is representative.Molysite has corrodibility, is easily formed residual, makes the water-band after process have color, cause secondary pollution; Hygiology finds the accumulation of aluminium salt in human body and current senile dementia have direct relation.Macromolecule organic flocculating agent, as polyacrylamide etc., itself does not have toxicity, but not easily decompose, also secondary pollution can be caused at occurring in nature long term accumulation, its acrylamide monomer has very strong " three cause " effect, polyacrylamide in 2006 in the output of China up to more than 30 ten thousand tons, its on a large scale application environmentally safe and human health can cause and have a strong impact on.

Flocculation agent is mainly used in sewage treatment area, can reduce the sense indexs such as the turbidity of former water, colourity, remove multiple macromolecule organic, heavy metal and radioactive substance.Flocculation both can have independently treatment system of one's own, also can combine with other processing unit process, as pre-treatment, intermediate treatment and final treating processes, also can be used for the concentration process before sludge dewatering, improved the dewatering of mud.

Generally use aluminium salt, polyacrylamide as the flocculation agent of water at present.This two classes flocculation agent in the application effect is general, and especially in sewage or more complicated sewage, effect is bad, can not adapt to the development in modern industry and city; And they have stimulation to human body and degradation property is poor, residual quantity greatly, can cause secondary pollution in water.

Summary of the invention
