Abstract
The present invention relates to sewage purification fields, specifically disclose a kind of flocculant for clarifying sewage.A kind of flocculant for clarifying sewage of the present invention, including Chinese small iris fibre bundle 30%~45%, povidone 5%~12%, polyaluminium sulfate 0.4%~0.9%, magnesium hydroxide 1.3%~1.7%, chitosan 11%~15%, hay bacillus 13% 17%, remainder is zeolite powder.The Chinese small iris fibre bundle is then added in the mixed liquor of alkali, bleaching agent, surfactant, accelerating agent after boiling drift 68 hours and is obtained by salt low-kappa number.The flocculant for clarifying sewage of the present invention provides microorganism and degrades to the pollutant in sewage, while carrying out flocculation to undegradable pollutant especially heavy metal, achievees the purpose that high-efficient purification water quality.
Description
Technical field
The present invention relates to sewage purification fields, specifically disclose a kind of flocculant for clarifying sewage.
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, bioreactor method, filtering embrane method etc., but above-mentioned effluent purification method centering water to the purification of sewage
In heavy metal processing capacity it is insufficient, the needs at present to sewage disposal cannot be met.
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 sewage purification waddings
Solidifying agent and preparation method thereof.
To achieve the above object, the present invention uses following scheme.
A kind of flocculant for clarifying sewage, which is characterized in that its component and mass ratio are：Chinese small iris fibre bundle 30%~45% gathers
Vinylpyridine ketone 5%~12%, polyaluminium sulfate 0.4%~0.9%, magnesium hydroxide 1.3%~1.7%, chitosan 11%~15%, withered grass
Bacillus 13%-17%, remainder are zeolite powder.
Wherein, Chinese small iris fibre bundle can not only enhance the removal ability of the heavy metal ion such as arsenic, lead and mercury, while improve wadding
The flocculation efficiency of solidifying agent.
The Chinese small iris fibre bundle is then added to alkali, bleaching agent, surfactant, accelerating agent by salt low-kappa number
It is obtained after boiling drift in mixed liquor 6-8 hours.
Further, the alkali is one or more in potassium hydroxide, sodium hydroxide.
Further, bleaching agent used be potassium percarbonate, potassium perborate, potassium sulfite, potassium pyrophosphate, potassium chlorite,
It is one or more in postassium hypochlorite.
Further, the surfactant is triethanolamine oleate, polyoxyethylene Chinese small iris oil, potassium oleate, 6- amino -2-
It is one or more in naphthalene sulfonic acid potassium.
Further, the accelerating agent is dimethyl sulfone, diethyl sulfone, benzene second sulfone, dibenzyl sulfoxide, dimethyl sulfoxide, diethyl Asia
It is one or more in sulfone.
Further, the alkali, bleaching agent, surfactant, accelerating agent mass ratio be 100:(10-25):(1-10):
(5-20)。
Beneficial effects of the present invention：The flocculant for clarifying sewage of the present invention provides microorganism and is carried out to the pollutant in sewage
Degradation, while flocculation is carried out to undegradable pollutant especially heavy metal, achieve the purpose that high-efficient purification water quality.
Specific implementation mode
For the ease of the understanding of those skilled in the art, with reference to embodiment, the present invention is further illustrated, real
The content that the mode of applying refers to not is limitation of the invention.
Embodiment one
The present embodiment provides a kind of flocculant for clarifying sewage, component and mass ratio are：Chinese small iris fibre bundle 45%, polyvinyl pyridine
Ketone 12%, polyaluminium sulfate 0.4%, magnesium hydroxide 1.3%, chitosan 11%, hay bacillus 17%, remainder are zeolite powder.
Embodiment two
The present embodiment provides a kind of flocculant for clarifying sewage, component and mass ratio are：Chinese small iris fibre bundle 30%, polyvinyl pyridine
Ketone 5%, polyaluminium sulfate 0.9%, magnesium hydroxide 1.7%, chitosan 15%, hay bacillus 13%, remainder are zeolite powder.
The preparation method of Chinese small iris fibre bundle：The Chinese small iris fibre bundle is then added to alkali, bleaching by salt low-kappa number
Agent, surfactant, accelerating agent mixed liquor in boil drift 6-8 hours after obtain..
The above content is only presently preferred embodiments of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention
Limitation.
