Description
Technical field
The present invention relates to sewage treatment fields, more particularly, to a kind of sewage disposal system.
Background technology
As development in science and technology and population increase, the discharge capacity of sanitary sewage and industrial wastewater is continuously increased, largely without having
The sewage direct emission of effect processing enters river, causes many rivers, especially medium or smallsized river, because pollutional load is more than its self-cleaning
Ability, and it is chronically at black smelly state.Under China's environment situation severe at present, black and odorous water problems demand solves.
The formation mechenism of black water-outlet body is mainly：Contain more organic pollution in the rainwater of sewage and rainwash,
When aerobic microbiological decomposing organic matter consumes a large amount of dissolved oxygen in the water bodys such as inflow river, water, reoxygenation rate is less than oxygen consumption speed
Rate, under anaerobic condition, microorganism is leading, anaerobic bacteria decomposing organic matter by the aerobic anaerobism that is changed into, and generation is largely insoluble in
Water has odour, such as ammonia, hydrogen sulfide escape the water surface, so that water body is given out unpleasant foul smell into air.In addition, gas
It can be involved in sludge in uphill process, water body is made to black；Meanwhile the water body of anoxic makes the heavy metals such as Fe, Mn restore, in conjunction in water
S formed FeS, MnS, also water body chroma and turbidity can be made to become larger.
Black and odorous water is very serious water pollution phenomenon, and water body is made to completely lose using function, and influence landscape and
Human lives and health.Black smelly harm is as follows：1) toxic and harmful gas generated in water body influences health；2) river is made
The purposes such as to drink, travelling, breed fish, swim and value is destroyed；3) it poisons or poisons organism in water with poison, make aquatile and aquatic bird
Deng disappearance, river ecosystem is destroyed；4) development for limiting city itself destroys the fine image in city.
Coagulation technology is that one of method of black and odorous water is effectively treated, it is by adding the chemical drugs such as molysite, calcium salt, aluminium salt
Agent makes suspended contaminant and dissolved phosphorus hydrochlorate formation insoluble solid in water body be precipitated in riverbed bed mud, but because of the technology
Limited processing to dissolved organic matter, can lead to the rebound of water pollution.
