Description
Technical field
The present invention relates to technical field of sewage, and in particular to a kind of municipal sewage treatment agent.
Background technology
Since population increases and economic development, excessive exploitation and unreasonable development to resource and the influence money that generates
A series of problems of source quality, these problems have directly threatened the existence of we and descendants.China is equally faced with
These problems, China are the countries of a water resources shortage, how to alleviate water resources shortage and have become the problems such as pollution
One it is very urgent the problem of.
With the fast development of national economy, city size constantly expands and the fast development of urbanization, urban industry are given up
The total emission volumn of water and sanitary sewage also increases year by year.If untreated waste water, sewage are directly discharged into natural water, not only can
It is serious to pollute the water quality of river, river, lake, library and underground water, and germ, virus, harmful substance and pernicious gas can be largely propagated,
Influence the quality of life and health of the people.
The method of sewage disposal has very much, but common are Physical and chemical method.Wherein, chemical Treatment sewage is people
It is most.And polyacrylamide is exactly most common water treatment agent in chemical method.Polyacrylamide is in water process work
Application in industry mainly includes three original sub-block, sewage disposal and Treatment of Industrial Water aspects.In original sub-block, polyacrylamide
Amine and activated carbon etc. are used cooperatively, cohesion and clarification available for suspended particulate in life water；In sewage disposal, polyacrylamide
Amine can be used and sludge dewatering；In Treatment of Industrial Water, it is mainly used as prescription medicament.In addition, in sewage disposal, using polypropylene
Amide can increase the utilization rate of water reuse cycle.It is existing although polyacrylamide plays very heavy effect in water process
It is typically all to use single polyacrylamide to have method, of high cost, it is inhibited to be applied even more extensively.Secondly, water resource is handled
Pollution problem has a variety of methods such as physics, chemistry, biology, synthesis, but physical method is mostly bad there are treatment effect, handling rate
Instability problem；Biological method processing cost is excessively high, is not suitable for promoting the use of；Mostly using chemical method come treated sewage, still
There is secondary pollution in existing sewage-treating agent, agent formulations, can also have a certain impact to environment.
Invention content
For above-mentioned deficiency in the prior art, it is dirty that the technical problems to be solved by the invention are to provide a kind of city
Water treatment agent.
The present invention seeks to what is be achieved through the following technical solutions：
