Technical field
The utility model relates to sewage treatment fields, more particularly, to a kind of sewage disposal system.
Background technique
As development in science and technology and population increase, the discharge amount 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 is solved.
The formation mechenism of black water-outlet body is main are as follows: contain more organic pollutant in the rainwater of sewage and rainwash,
When flowing into the water bodys such as river, aerobic microbiological decomposing organic matter consumes a large amount of dissolved oxygen in water, and reoxygenation rate is lower 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 atmosphere.In addition, gas
It can be involved in sludge in uphill process, water body is made to black；Meanwhile the water body of anoxic restores the heavy metals such as Fe, Mn, 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 water pollution phenomenon very serious, completely loses water body 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 human 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 in city itself is limited, the fine image in city is destroyed.
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 is precipitated to suspended contaminant and dissolved phosphorus hydrochlorate formation insoluble solid in water body in riverbed bed mud, but because of the technology
Limited processing to dissolved organic matter, will lead to the rebound of water pollution.
