Description
Technical field
It a kind of is polluted the present invention relates to a kind of in-situ remediation method of polluted-water more particularly to using composite enzyme
The in-situ remediation method of water body.
Background technology
With the improvement of people ' s living standards and the quickening of urbanization process, sanitary sewage is more and more, by these dirts
It is very necessary that water, which effectively administer,.With the increase of sewage discharge and the enhancing of environmental consciousness, polluted-water is controlled
Reason also gradually attracts attention.
Occur various sewage water treatment methods at present, representative example is activated sludge process.This method includes such as
Lower step：Sewage disinfection treatment, sludge seeding, sludge for agricultural use (appropriateness aeration), one third of first gradually intaking simultaneously start to expose
Gas, and design water level is progressively reached, secondary settling tank is started, secondary settling tank water inlet starts sedimentation basin, and sludge flows back at regular time and quantity.According to
State adjusts regurgitant volume and time, and extra-nutrition object decomposes sewage ability to cultivate micro organism quantity and improve, and starts follow-up dirty
Water treatment facilities, such as sludge settling pond plus chemicals, sanitizer and sludge treatment equipment.Activated sludge front end is at biology
Reason, the mode for taking aerobic-anaerobic to ferment decompose harmful substance in water, and in order to reach settled sludge and sterilisation purpose, centre is adopted
With chemicals, such as flocculant, rear end takes the modes such as carbon granule filtering to make water qualified discharge.The processing rear end of this method uses
Chemical agent, disinfection also kill beneficial microbe in sludge while removing harmful substance, make returned sludge microbial activity
It reduces, cannot fully ferment decomposing harmful substances.The water activity reduction of discharge be easy to cause secondary pollution, no nutrition, Bu Nengjin
One step is used for the improvement of polluted-water.
Therefore, exploitation does not need the pollution waters restoration technology of chemical reagent and is still necessary.
Invention content
The purpose of the present invention is to provide a kind of in-situ remediation methods of polluted-water, need not use the changes such as flocculant
Learn drug.Further aim of the present invention is to provide a kind of in-situ remediation method of polluted-water, pollution control cost compared with
It is few, but it is wide to administer area.
The present invention provides a kind of in-situ remediation method of polluted-water, includes the following steps：
(1) pretreating zone is formed in polluted-water；
(2) it is carried out in the pretreating zone using the nutrient solution obtained after composite enzyme and composite enzyme treated sewage micro-
Biocompatibility culture obtains culture water body；
(3) in-situ immobilization is carried out to the polluted-water using the culture water body；
Wherein, the composite enzyme is obtained by step (4)：Plant is utilized in the first fermentation raw material containing malt sugar
Ferment carries out the first fermentation, obtains the first zymotic fluid, then using described in the second fermentation raw material containing malt sugar and wheat bran
First zymotic fluid carries out the second fermentation, obtains composite enzyme, and total bacteria count is 3 × 10 in the composite enzyme5~3 × 109CFU/
Ml, lactic acid bacteria account for 80% of total bacteria count or more, and actinomyces, photosynthetic bacteria, nitrogen-fixing bacteria, bacillus subtilis and saccharomycete account for 10~
20%；
Wherein, the nutrient solution is obtained by step (5)：The composite enzyme that step (4) obtains is mixed with sewage, and
Aerated fermentation is carried out, to obtain nutrient solution.
In the present invention, step number is convenient just for the sake of description, and method of the invention might not be according to step sequence
Number carry out.In the present invention, polluted-water usually indicates contaminated natural water or irrigation canals and ditches water body etc..Contaminated degree is not
