S2, then the pH of filtrate is adjusted to 6~8, special release agent, sedimentation separation is added；
Waste water after separation is sent into biological contact oxidation pond and carries out biological contact oxidization treatment, reducing agent is then added by S3, and
Processing is filtered using active carbon filtering technique, then carries out settlement treatment to get filtered industrial wastewater is arrived；
S4, filtered industrial wastewater are filtered processing using security personnel's filtering technique, then use micro-filtrate membrane filtration technique into
Row filtration treatment, then processing is filtered using ultrafiltration membrance filter technique, the discharge water for meeting environmental protection standard can be obtained.
Preferably, the organic loading of the anaerobic reactor is 10~20kgCOD/m3D, hydraulic detention time 10~
15h, operation temperature are 40~70 DEG C.
Preferably, the special release agent includes powdered sodium carbonate, carbonic acid iron powder and nano titanic oxide catalyst powder
End, the molar ratio of the powdered sodium carbonate, carbonic acid iron powder and nano titanic oxide catalyst powder are 1:1-2:2-5.
Preferably, in the S1, waste water to be processed is sent into anaerobic reactor after conditioning tank, oil separator removing oil slick and is carried out
Processing, then carries out pH again and is adjusted to 4, filtrate is obtained by filtration.
Preferably, the molar ratio of the powdered sodium carbonate, carbonic acid iron powder and nano titanic oxide catalyst powder is 1:
2:5.
Preferably, in the S2, then the pH of filtrate is adjusted to 7, special release agent, sedimentation separation is added.
Compared with prior art, it is floated the beneficial effects of the present invention are: being removed by waste water to be processed through conditioning tank, oil separator
It is sent into anaerobic reactor after oil to be handled, then carries out pH again and is adjusted to 3~5, filtrate, acidification, reduction pair is obtained by filtration
The adverse effect of subsequent biological treatment；By the way that the pH of filtrate is adjusted to 6~8 again, special release agent is added, sedimentation separation is special
Release agent includes powdered sodium carbonate, carbonic acid iron powder and nano titanic oxide catalyst powder, the powdered sodium carbonate, ferric carbonate
The molar ratio of powder and nano titanic oxide catalyst powder be 1:1-2:2-5, can in waste water high calcium, high organic matter into
Row reaction removal, forms precipitating, and reaction effect is good, high-efficient, at low cost, is suitble to promote the use of.
