Description
Technical field
The present invention relates to water treatment field, more particularly to a kind of water treatment agent, meanwhile, further relate to the preparation of the water treatment agent
Method.
Background technology
Water process is to go in water removal some to the unwanted nuisance that produces, lives by physics, chemistry, biological means
The process of matter, is sedimentation, filtering, coagulation, flocculation, inhibition and scale inhibition for being carried out to water to be applied to specific purposes etc.
The process of water quality conditioning.With the worsening shortages of water resource, the consciousness of people's water conservation gradually strengthens, and water process is ground
Study carefully and seem more and more important.China is a country for severe drought water shortage, if untreated for life and industrial wastewater straight
Run in put and greatly harm can be brought to water body and aqueous bio, and developing rapidly with industry, the species sum of waste water
Amount is swift and violent to be increased, and the pollution to water body is on the rise.Mainly there are Physical, chemical method, bioanalysis for the processing method of waste water
Three major types, conventional physical method has gravitational separation process, absorption method；Chemical method is mainly by adding salt electrolyte, flocculant
Processed Deng to waste water；Bioanalysis mainly divides activated sludge process and bioanalysis.The waste water complicated for water quality generally require into
The comprehensive treatment of row, physics, chemistry and biological treatment are combined, and can be only achieved processing requirement, but water process conventional at present
Agent, single dose is difficult to meet process demand because the restriction effect of medicament physico-chemical property is single, and multiple agent by principle of compound because being limited medicine
The less stable of agent, is unfavorable for application, it is therefore desirable to research and develop that stability is high, effect comprehensively, be easy to apply, treatment effect
Good water treatment agent.
The content of the invention
It is to solve the deficiencies in the prior art, the invention provides a kind of stability is high, at high treating effect water
Manage the preparation method of agent.
