Brief description
Accompanying drawing 1 is the utility model structural representation.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.The utility model discloses it is a kind of
Productive life sewage zero-discharge processing system, processing system includes sewage primary treatment part, advanced treatment of wastewater purification part,
Sewage primary treatment part includes grille well, oil interceptor, regulating reservoir and anoxic pond, through grille well, oil interceptor, regulating reservoir and anoxic
After sewage after the process of pond is processed through biomembrane reaction pond and milipore filter reaction tank again, and the sterilization of sterilized pond enters sewage deep
Treatment and purification part is purified.
Deep purification of waste water process part includes counter-infiltration system, and counter-infiltration system includes being sequentially connected the security personnel's filtration connecing
Device and reverse osmosis unit, can obtain meeting the pure water of zero emission requirement after processing through counter-infiltration system, this pure water enters in pure water pond
Temporary.
Sterilization pool in the system is provided with middle water intake, takes from this intake and can be taken off middle water.
Sewage, after drainage system collection, enters grille well, and after grille well removes granule foreign, sewage enters oil removal
Pond, after removing the grease of suspension in oil interceptor, sewage enters in regulating reservoir.It is provided with preaeration system in regulating reservoir, be additionally provided with liquid
Position controller, after liquid level controller monitors that in regulating reservoir, water level meets the requirements, pump will start, and sewage is pumped to anoxic by pump
Pond, be hydrolyzed in anoxic pond acidification, to reduce the concentration of organic matter, removes part ammonia nitrogen.
Remove the sewage after part ammonia nitrogen through anoxic pond and enter biomembrane reaction pond, carry out aerobic biochemical reaction, here is exhausted
Most of organic dirt is degraded by biological oxidation and absorption.Water outlet carries out biology after flowing to milipore filter reaction tank further
Oxidation, absorption and UF membrane, the water outlet after process enters sterilization pool, adds sodium hypochlorite, had with killing in water in sterilization pool
Standby after evil bacterial classification.The purpose of milipore filter reaction tank setting is to go further suspension in eliminating water, colloid, colourity, turbidity
With the impurity such as organic matter, to lift water purification quality.It is provided with milipore filter in milipore filter reaction tank, the ultrafiltration membrane material of this element
Matter is the doughnut of pvdf, and this doughnut surface active layer is fine and close, and its supporting layer is spongy network structure, therefore this ultrafiltration
