Study On Operation And Control Of Waste Water Treatment Plant About A/O Process

After research comparing with deveLop for many years, since A/O handicraft having out- water stabiLization, putting up water phosphorus contents Low , precipitate a function out weLL , run way nimbLy, the sLudge does not expand to wait for a Lot of merit , this handicraft aLready becomes one kind of main handicraft form of sewage treatment factory , aLready graduaLLy, mature and arouse extensive use. Therefore how to bring A/O handicraft into pLay is handLed becomes one of the probLem that the insider shows soLicitude for.The theory research to A/O handicraft is concentrated on severaL aspect mainLy: (1) A/O handicraft's get rid of phosphorus mechanism and effect (2) A/O handicraft's escape from nitrogen mechanism and effect (3) A/O handicraft simuLtaneous get rid of the phosphorus and nitrification mechanism and effect. But, the reaLity to A/O handicraft produces operation under the controL of studying taking Lack seriousLy. The author has run to A/O handicraft fouL water factory design , starting , Long-time running effect has carried out the systematic summary and thorough investigation and discussion. Research thinks: The A/O handicraft has BOD , COD , SS takeoff rate water than high takeoff , has higher takeoff rate to the phosphorus , has very high nitrification efficiency to the nitrogen.Owing to that as said or narrated above, the viewpoint has been at the same time guided by director professor , the author has accompLished A/O handicraft sewage treatment, the factory works and studies under the controL of. Be to reaLize A/O handicraft highLy efficient operation, the author has carried out theory on the probLem appearing in operation studying and summing up , has been on the march to the method resoLving these probLems's to study.In the process of experiment, the author has insisted that the tracking being in progress to detecting index every day observes , has anaLysed aLmost thousand together having the effect data, Large amount of data has demonstrated write brought forward the theory correctness , can't be a thesis this at the same time by author has Laid down soLid basis.A/O sewage treatment handicraft that this research institute studies, aLready, sewage treatment having the actuaL project , the thesis research to have identicaL handicraft or the cLose handicraft to other in many city of the whoLe nation range inner the factory design , runs and has under the controL of certain reference vaLue. Investigation and discussion that these evidentLy experience, the operation under the controL of being a sewage treatment factory is provided drawing Lessons, has the significant economic effect , sociaL benefits and environmentaL benefits to deveLopment of the cause driving our country sewage treatment.
