Description
Technical field
The present invention relates to sewage purification field, a kind of purifying agent for polluted water and preparation method thereof is specifically disclosed.
Background technology
The smelly phenomenon of water body is the organic matter anaerobic digestion in water body as a result, organic matter disappears during anaerobic digestion
A large amount of oxygen are consumed, water hypoxia is caused, make anaerobe mass propagation and decompose to generate the effusion water surface such as ammonia, hydrogen sulfide,
And water hypoxia inhibits the growth and breeding of beneficial microbe, aquatic animals and plants, and the aerobic effect of microorganism is made to weaken significantly,
The reduction of the heavy metals such as iron in water, manganese is also resulted in, forming ferrous sulfide etc. with the sulphur in water makes water body that black be presented.
There are chemical method, flocculant method, bioreactor method, filtering embrane method etc., but above-mentioned sewage purification to the purification of sewage
The huge processing equipment of method some need, some process cycles are very long, and some methods even can have ecological risk or right
Environment causes secondary pollution, cannot meet the needs to sewage disposal at present.
Invention content
In order to overcome shortcoming and defect existing in the prior art, the purpose of the present invention is to provide a kind of purifying agent for polluted water
And preparation method thereof.
To achieve the above object, the present invention uses following scheme.
A kind of purifying agent for polluted water, by polyhydroxyalkanoates, mannosylerythritol lipid, zeolite powder, alkyl glycosides, hawthorn
Acid, diatomite composition.
The purifying agent for polluted water of the present invention is in cesspool, purifying agent for polluted water to be put into based on polyhydroxyalkanoates
As the time gradually degrades after cesspool, and release the microbial activities such as mannosylerythritol lipid, alkyl glycosides, crataegolic acid
Agent.The microbial activity agent combination that mannosylerythritol lipid, alkyl glycosides in purifying agent for polluted water, crataegolic acid are formed, can be with
The ability of various microbial degradation pollutants in cesspool is greatly improved, to reach purpose of purifying the water quality.
Further, each component and content are respectively 75-90 parts of polyhydroxyalkanoates, mannosylerythritol lipid 4-15
Part, 34-45 parts of zeolite powder, 20-25 parts of alkyl glycosides, 20-32 parts of crataegolic acid, 5-12 parts of diatomite.
Further, polyhydroxyalkanoates can be selected from poly 3-hydroxy butyrate, poly- (3-hydroxybutyrate ester -3- hydroxyls penta
Acid esters), poly- (3-hydroxybutyrate ester -4 hydroxybutyric acid ester.
Further, the prodegradant is a kind of in polycaprolactone, polyvinyl alcohol, poly butylene succinate, starch
Or it is a variety of.
The rate of release of suitable microbial activity agent can be selected according to water quality characteristics, the rate is by adjusting sewage purification
The degradation rate of agent is realized, can be increased degradation in purifying agent for polluted water when needing quick release microbial activity agent and be helped
The amount of agent, it is on the contrary then prodegradant need not be added.
The preparation method of purifying agent for polluted water is：Raw material is put into grinder according to the ratio, slurry, which is ground to granularity, is
0.4-0.5 microns；Wherein, raw mixture：Ethyl alcohol：The mass ratio of glycerin monostearate dispersant is 57：42.6：1.4；
Obtained slurry is crossed into 600 mesh sieve, is then driven into centrifugal spraying granulator by peristaltic pump and carries out granulating and drying, obtain dirt
Water scavengine agent..
Beneficial effects of the present invention：By forming purifying agent for polluted water based on degradable material, while purifying sewage
Slowly degradation and releasing microbe activating agent realize the long-term purification function of microbial activity agent, and to a variety of pollutions in sewage
Object can play preferable treatment effect.
