Description
Technical field
The present invention relates to sewage to repair field, more particularly to a kind of ecological selfreparing photo-thermal microbial treatment sewage
Method.
Background technology
Water resource is human being's production and the essential natural resources of living, and the environmental resource depended on for existence of biology and
The economic resources for supporting national economy to develop in a healthy way.Since the industrial revolution, the rise of big industry, the mechanization of agricultural and agricultural chemicals
A large amount of uses of chemical fertilizer, urbanization develop rapidly, cause a large amount of waste water to be discharged into rivers,lakes and seas, cause the deterioration of water environment.
And as the shortage of water resource and water quality deterioration cause the ecosystem in river also seriously to degenerate, soil erosion is caused, embankment is invaded
Phenomena such as erosion is seriously and bio-diversity reduces.Urban landscape is to include artificial lake, small-sized natural lake with water and is room
Man-made tourist site lake that real estate construction is configured etc., it is in the particular surroundings for differing larger with natural environment, and its majority is quiet
Only or the poor slow flow water bodies of mobility, therefore the self-purification capacity deficiency of water body, easily as sanitary sewage, rainwater and rubbish etc.
Receptor, cause different degrees of water pollution, or even eutrophication.
Municipal sewage is mainly made up of four parts, including：Caused sanitary sewage, each enterprise during life of urban resident
The surface water that caused production waste water, urban precipitation and part are contaminated in process of production.Municipal sewage it is biochemical
Better performances, usual BOD5/ COD can reach 0.5~0.6, distinguishing feature be water quality, water change have seasonal periodicity and
Daily cycle property；China's most area sanitary sewage pretreatment is in units of zonule, and pretreated water is via sewerage system
It is directly discharged into natural water；Life, office and shopping centre mix, and sanitary sewage shares a set of sewer with urban sewage
System.Therefore, amount is big, source is more, wide the characteristics of being China's city domestic sewage.
According to the difference of municipal sewage treatment principle, urban sewage treatment technology can be divided into Physical, chemical method and life
Thing method.Biological treatment is that solve the problems, such as that municipal sewage is most economical, the most effective and method that is most widely used, is that water resource can
The important guarantee of sustainable development.The principle of Sewage Biological Treatment is provided with bioreactor beneficial to microorganism enrichment and life
Long condition, mainly include nutritional condition and dissolved oxygen conditions, strengthen and accelerate microorganism to various organic pollutions with this
Effective degraded, reach purification sewage purpose.
Number of patent application CN201610974967.9 discloses microorganism pollution treatment and system and microorganism pollution treatment microbial inoculum occurs
The microorganism contamination governing method of system occurs for preparation method and microorganism pollution treatment, with the micro- life of microbiologic properties analytical technology pure culture
Thing, by quantitative sample inoculation in culture medium, cultivated under preference temperature in incubator the regular hour, but incubation
The original environmental condition of microorganism unavoidably is deviated more or less from, causes the transformation of biological community structure, it administers dirty
The effect of water will have a greatly reduced quality.
Number of patent application CN103787475A discloses a kind of high efficiency sewage treating agent, including inorganic natural mineral matter 40~
60 parts, 20~40 parts of mineral sulfates, 10~30 parts of inorganic carbonate or alkali, 1~5 part of inorganic polymeric sulfate.
Although the chemicals for water remediation disclosed in prior art plays certain during water remediation
Effect, but these preparations have significant limitation and specific aim, such as coagulant can only play coagulation；Decolorising agent can only
Decolouring etc. is played, these preparations are only capable of shifting pollutant, it is impossible to fundamentally remove the pollution factor in water body, and shape
Into substantial amounts of sludge, secondary pollution is caused.
The content of the invention
