Description
Technical field
The present invention relates to microorganism and technical field of water body purification, and in particular to a kind of complex microorganism water purification agent and its system
Preparation Method and application.
Background technique
Water treatment problems are always that one of problem is paid close attention in the whole world.In the world, the water consumption of various regions is all
Increasing rapidly.At the same time, water pollution problems is got worse, and serious water resource supply and demand all occur in many areas and country
Contradiction.Therefore how lifting sewage processing capacity, so as to herein using just seeming particularly important.Current water main in the world
Pollution sources mainly include industrial pollution, agricultural pollution and sanitary sewage.
Mainly there are five aspects, respectively pathogen pollution, aerobic organic pollution, richness for harm caused by various sewage
Nutrient laden pollution, stench etc. harm.Pathogen pollution is most of to be derived from city and domestic sewage in rural areas, hospital's dirt
Caused by water etc..Aerobic organic matter is a large amount of dissolved oxygen progress microorganism decomposition of post consumption for being directly discharged into water body mostly,
Water pollution is also increasingly severe.Eutrophication pollution refers to that Water, phosphorus nutrition substance are excessive and cause water pollution.It dislikes
Bromomenorrhea often occurs in polluted-water, it is a kind of very common contamination hazard.Acid, alkali pollution will cause water body pH value
Change, so that its buffer function is reduced, so that water body self-purification ability declines.Water pollution problems has influenced the normal of people
Life, becomes a hot issue urgently to be solved.
Improveing the method to purify water at present mainly has physical method, chemical method and bioremediation.Physical method
It is that the impurity such as suspended organic matter in water are removed by filtering, precipitating, absorption.This method is small to secondary pollution of water, but provides
Source waste is big；The organic matter to suspend in water can only be sunk to bottom of pond by precipitating, absorption, can not can be reduced in water with water-outlet body
The total amount of organic matter.Chemical method usually improves water quality with chemicals such as copper sulphate, bleaching powder, malachite greens, it is acted on fastly,
But secondary pollution is caused to environment and soil, the damage for being difficult to repair is caused to water body, the residual hazard that most preparations leave seriously is endangered
Evil aquatic products and human health.Biological treatment is that microbial bacteria flora forms advantage in artificial promotion water, utilizes microorganism
Contaminant degradations, conversion, the absorptions such as organic matter, nitrogen, phosphorus in water body it is net to be finally reached water quality by assimilation and dissimilation
Change purpose.The technology of microorganism decomposition processing polluted-water is more and more extensive to be applied, in the prior art, common microorganism
Microbe species are more single in water purification microbial inoculum, are not thorough to the resolution process of water body, therefore, it is dirty to need a kind of resolution process water body
Contaminate good, the economic and environment-friendly compound micro- complex microorganism water purification agent of effect.
The Chinese patent application of 104445635 A of Publication No. CN discloses a kind of high-performance bio water purification agent and its preparation
With application method, which is made of microorganism, biological enzyme and flocculant three mixing, micro- life
Object by bacillus, nitrobacteria, photosynthetic bacteria, streptococcus, actinomyces, polyP bacteria, saccharomycete mixing form, biological enzyme be by
Lipase, amylase, phytase, pectase, cellulase, lignoenzyme mixing composition, flocculant are by aluminium polychloride, gather
Ferrosilite, polyacrylamide mixing composition, since the complex microorganism water purification agent is directly to throw biological enzyme into the water, it is difficult to
Guarantee the activity of enzyme, clean-up effect is difficult to ensure.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of complex microorganism water purification agent and its preparation side
Method and application.The complex microorganism water purification agent can fundamentally realize to water body disinfection, degradation water body harmful substance pollution,
It converts water body surplus ammonia and nitrogen organic, restore water body microecological balance, have both water purification, oxygenation, adjust the effect of flora, and nothing
Secondary pollution has the advantages that efficient, environmentally protective.
