Water collecting-tank, aerobic and anaerobic biological system, second pond, intermediate pool, ultrafiltration membrane treatment device and clear water reserviors；Wherein, flocculation
Sedimentation tank is also connected with sludge concentration tank, and sludge concentration tank is also connected with sludge filter press；The mud produced is discharged to sludge condensation
Pond concentrates, and then transports after sludge filter press filter pressing；Second pond is provided with reflux, and water therein can be back to
Oxygen and the mud in anaerobic biological system, second pond can also be discharged to concentrate in sludge concentration tank.
Preferably, the outlet of described intermediate pool is also connected with wet oxidation processing means, and wet oxidation processes dress
Put and be also connected with ultrafiltration membrane treatment device.Intermediate pool processes may select when occurring abnormal and first carry out wet oxidation process, then
Enter back into ultrafiltration membrane treatment operation and carry out air water ultrafiltration membrane treatment.
Preferably, the outlet of described clear water reserviors is also connected with activated carbon adsorber.If abnormal feelings occur in Chu Liing
Condition, is incorporated into discharge or reuse again after processing in activated carbon adsorber by the water in clear water reserviors.
Preferably, the water inlet of described aerobic and anaerobic biological system is also connected with Living Water collecting-tank.Because adding
Sanitary sewage or add adequate nutrition salt and can improve the biodegradability of waste water.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
1. Technology advanced person, high treating effect, after treatment, COD is dropped below 60mg/ by about 7000mg/l
L, BOD are less than 20mg/l.
2. the oil in waste water can with recycling, evaporative desalination generate anhydrous sodium sulfate can as commodity selling,
The increment achieving by-product utilizes, thus reduces the operation cost of whole system, achieves many things at one stroke.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is expanded on further.
As it is shown in figure 1, this utility model is first to be incorporated into by waste water in the two-stage water tank 1 being used in series, play standing
The purpose of oil removing, when water COD superelevation, returns waste water with pump again and again processes to workshop；Set two-stage water tank 1 is supporting
It is equipped with elevator pump, waste water lifting will be produced uniformly with pump to grease removal tank 2.Heating coil, top it is provided with bottom grease removal tank 2
It is provided with extruding belt type oil removing machine, utilizes the extraordinary oil suction band of oleophilic drainage to be taken out of by oil slick in pond, skimming after extruding；
Waste water pump after oil removing is promoted to MVR vapo(u)rization system 3 and carries out desalting processing.The main one-tenth of the solid salt that evaporation produces
It is divided into anhydrous sodium sulfate, as selling process outside commodity；Iron-carbon micro-electrolysis device 4, profit is entered after evaporation condensate upon mediation pH value
