The sewage-treatment plant of purification.
Background technology
Currently, the processing structure form of effluent treatment plant is mostly based on rectangle, each sewage treatment unit includes grid
Between, anaerobic pond and artificial swamp be attached respectively by pipeline or elevator pump, sewage flows in the horizontal direction in each unit
It crosses.The Structural visual effect of this rectangle processing unit is poor, and inside be easy to cause dead angle position, and connecting pipe is easy to block, pass
Defeated distance need to pass through and be repeatedly lifted up, and energy consumption is big, fails to make full use of the surface microorganism filler of each unit hypothallus to go to play
The effect of purification of water quality.
In addition, at present mainstream sewage purification technology based on activated sludge process, based on activated sludge to waste water
In be continuously passed through air, after a certain period of time, aerobic microorganism breeding can form sludge-like flocculate for operation, utilize activity dirty
Biological flocculation and precipitation, absorption and the oxidation of mud, to decompose the organic pollution removed in sewage, then again by sludge and moisture
From most of sludge flows back into aeration tank again, and activated Sludge System is then discharged in redundance.Using the processing method, although not
It is different using the treatment and purification effect of this method with the wastewater influent of degree, but most of treated that level-one is still not achieved in water quality
The water standard of A is still pollution sources for surface water environment, causes water body long even if water outlet reaches the standard of level-one A
Phase is in bad five classes water level, influences environmental sanitation and common people's health；Secondly the processing method excessively relies on the effect of microorganism,
Decomposition, absorption detach entirely by microorganism progress, if exception occurs in micropopulation kind, it will cause total system collapses, use
There are instabilities.
