Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Referring to Fig. 1, a kind of sewage disposal system, it is characterized in that: include oil interceptor 1, magnetization reactor 2, strong magnetic separation reactor 3, magnetic kind regeneration reactor 4, centrifugal pump 5, magnetic kind regeneration strong magnetic separation device 6, it is characterized in that: have oil removing dirt separator 12 in described oil interceptor 1, oil removing dirt separator 12 has oil scraping plate 13；Respond in described magnetization reactor 2 agitator 24；Strong magnetic roller A33 is had in described strong magnetic separation reactor 3；Regeneration dispersing stirrer 43 is had in described magnetic kind regeneration reactor 4；Strong magnetic roller B63 is had in described magnetic kind regeneration strong magnetic separation device 6；Connected by pipeline between described oil interceptor, magnetization reactor, strong magnetic separation reactor, magnetic kind regeneration reactor, magnetic kind regeneration strong magnetic separation device, pipeline has valve, the flowing of sewage can be controlled.
Described oil interceptor 1 has defat wastewater inlet A11 and oil interceptor outlet A14, against there being oil scraping plate 13 on oil removing dirt separator 12.
Having wastewater inlet B21, outlet B22 and magnetic kind import 23 in described magnetization reactor 2, internal-response agitator 24 is controlled by the motor on top.
Import C31 and outlet C32 is had, against there being scraper plate A34 on internal strong magnetic roller A33 in described strong magnetic separation reactor 3.
Having clear water import D41 and outlet D42 in described magnetic kind regeneration reactor 4, internal regeneration dispersing stirrer 43 is controlled by the motor on top.

Described magnetic kind regeneration reactor 4 regenerates strong magnetic separation device 6 by pipeline with magnetic kind and is connected, and pipeline has centrifugal pump 5.
Concrete operation method:
1. defat: defat sewage is entered in oil interceptor 1 by the import 11 of oil interceptor 1, dirty water float greasy dirt by oil removing dirt separator 12, greasy dirt is sticky deposited on the transfer roller of the oil removing dirt separator 12 rotated at a slow speed, processes by greasy dirt being scraped centralized collection with transfer roller immediate oil scraping plate 13.
2. magnetization sewage: exclude the sewage after oil by exporting A from flowing into magnetization reactor 2, the magnetic kind import 23 of magnetization reactor 2 add ferroso-ferric oxide magnetic kind powder, reacted by the stirring action of reaction stirrer 24；Magnetic kind powder belt is magnetic and very tiny of 150 order-200 orders, by the magnetic of tiny magnetic kind, the float such as the greasy dirt in sewage and iron plate are scrubbed rust powder and magnetized, greasy dirt and iron powder after magnetization are undertaken assembling cohesion by mutual magneticaction, eventually become the microgranule group that particle diameter is bigger, and be the microgranule group with certain magnetic force.
3. separate: flowed into strong magnetic separation reactor 3 by exporting B22 through import C31 by the sewage after magnetizing reactor 2 magnetization, under the magnetic attraction effect of the strong magnetic roller A33 of strong magnetic separation reactor 3 slow rotation, original magnetized greasy dirt microgranule group being given and inhales on strong magnetic roller A33, the clean liquid with degreasing agent is returned the reuse of defat workshop section by exporting C stream；Degreasing agent liquid and greasy dirt and the sharp separation of magnetic kind mixture is achieved by magneticaction；It is attracted to the greasy dirt on the strong magnetic roller A33 of slow rotation and magnetic kind mixture is scraped by scraper plate and automatically falls in magnetic kind regeneration reactor 4.
4. clean: in magnetic kind regeneration reactor 4, greasy dirt and the dilution of magnetic kind mixture that scraper plate is scraped by a small amount of clear water is added by clear water import D41, greasy dirt and magnetic kind are spread out by the dispersion force simultaneously produced by regenerating dispersing stirrer 43 high-speed rotation, are broken up separation by original magnetic greasy dirt Ci Zhong microgranule group.
5. sewage discharge: the greasy dirt magnetic kind mixed solution after dispersion separation, by outlet D pipeline by centrifugal pump 5 pump to import E61, is transported in magnetic kind regeneration strong magnetic separation device 6.Regenerating in magnetic kind under the magnetic attraction effect of strong magnetic roller B63 of strong magnetic separation device 6 slow rotation, magnetic kind is drawn onto on strong magnetic roller B63, and the solution containing greasy dirt is flowed sewage disposal system by effluent discharge outlet E62 and carries out conventional treatment.The magnetic kind being drawn onto on strong magnetic roller B63 is also mixed with a small amount of greasy dirt, need to use for this and rinse the clear water mouth of pipe 65 ejection flushing clean water once.The magnetic kind cleaned up is scraped by scraper plate B64 automatically fall in magnetization reactor 2 inhaling magnetic kind on the strong magnetic roller B63 of its rotation, the utilization it is achieved thereby that magnetic kind moves in circles.
The above; being only the present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope that the invention discloses; the change that can readily occur in or replacement, all should be encompassed within protection scope of the present invention.
