Description

A kind of water pollution administering method based on microbial method
Technical field
The invention belongs to water pollution Treatment process field, be specifically related to a kind of water pollution administering method based on microbial method.
Background technology
In recent years, along with the sustainable growth of China's economy and the quickening day by day of urbanization process, city size is expanded rapidly, urban population sharply expands; Meanwhile, the source of pollution in a large number containing nitrogen, phosphoric nutritive substance also enter in the water bodys such as river course, lake, reservoir continuously, and the Nutrient loads amount of water body is constantly increased, and water quality condition worse and worse.
At present, the eutrophication of water body has become the comparatively outstanding environmental problem of one, China.
(1) also there is eutrophication, as Huangpu River Basin, Guangzhou Section of Pearl River etc. in part section in some rivers.
(2) many large-size lake, as Chaohu, Taihu Lake, Poyang Lake, Dian Chi etc., have all been in eutrophy or heavy eutrophic state.
(3) some reservoirs also receive pollution in various degree and have had influence on the drinking water safety of resident.
Due to water body once enter the eutrophy stage will lose its due function, affect economic construction and social development, water pollution administer become create civilized communities, one of faced problem in the urgent need to address of building a harmonious society.
Traditional water pollution administering method spatially position division can be divided into dystopy facture, in situ treatment, bypass treatment.The treatment effect of dystopy facture depends on Technology and the operation conditions of the sewage work built in strange land completely, and construction investment costly.In situ treatment comprises Physical, chemical method, aeration, throwing bacterium method, biomembrance process, plant method, animal law etc., although do not need the pipe network system of separately building shunting, whole river directly processes in river course, lake.Bypass treatment comprises land treatment systems method, oxidation pond process, artificial-strengthening bio-reactor method etc., the typical method land treatment systems method in this method, and in general, there is floor space comparatively large, long-time running also exists the problem of filling soil property or clogged with material.
In Practical Project, adopt the more of in situ treatment, as the method such as Physical (desilting, water distribution, substrate sclerosis, open channel cover), chemical method (algae is killed in dispensing), aeration, throwing bacterium method, some engineering additionally uses combination process, these methods have effect that can be certain, but there is following problem:
A () destroys original ecosystem, as desilting method.
B () is costly, as substrate hardening process.
C () is cured the symptoms, not the disease, easily recur, there is secondary pollution, as chemical method.
D () combination process falls flat, as chemical method+throwing bacterium method+artificial floating island, Unit selection non-optimal, combining is not play the effect of mutually promoting, and what have also plays negative effect.
Summary of the invention
For above-mentioned problems of the prior art, the object of the present invention is to provide a kind of water pollution administering method based on microorganism avoiding occurring above-mentioned technological deficiency.
