d：Liquid of the step c after processed is introduced into neutralization pond+biological nutrition liquid pool, hydrochloric acid is added into neutralization pond and adjusts waste water
PH adds and breeds aerobic and oxygen complex microorganism to 6-9, and is aided with aeration and carries out organic matter degradation and nitrification processing,
To the COD contents in degrading waste water, time 45-60min；
e：Liquid after step d degradation treatments is introduced into biomembrane processor, and the film of biomembrane processor is discharged and is introduced
Ultraviolet ray disinfector carries out sterilization treatment；
f：It will pass through by the middle water after sterilization treatment in step e and relay water tank introducing multimedium air bump rinse operation little Chi, use
More medium filter, chamber filter press and chemicals dosing plant centering water is filtered, is separated by solid-liquid separation and purified treatment；
g：Step g is discharged by the middle water after purified treatment by middle water tank, realizes the zero-emission of waste water.
Further, the pretreatment operation of the waste water in step a in preliminary sedimentation tank is：Into preliminary sedimentation tank be added PAC, PAM and
CaO so that the suspended matter removal in waste water, and it is continuously added NaOH or H2SO4To adjust acid-base value.
Further, the precipitation generated in step c is transported to the precipitation generated with primary sedimentation tank in chamber filter press and carries out
Solid-liquid separation treatment forms mud cake.
Further, the aerobic and oxygen complex microorganism for adding and breeding in step d is H type high efficiency composition floras.
Further, in step f the job content of more medium filter include just wash, gas backwash and water backwash.
The beneficial effects of the invention are as follows：The present invention is dropped by first heavy, hydrolysis acidification, flocculation sediment, the organic matter to waste water
The processes such as solution, disinfection, sand filtration carry out integrated treatment, and handle rear fully recovering up to standard to cleaning process, realize the zero of waste water
Discharge and cycling and reutilization, economical environment-protective, greatly reduce the cost input of enterprise, convenient for improving economic benefit and the society of enterprise
It can benefit.
