Research Of Key Technology In Total Drained The Sewage Treatment Crafe Of Baogang

According to Total drained the sewage treatment craft of BaoGang and pollution factor got rid of mainly: suspended material, COD and oil can know Total drained the sewage treatment craft of BaoGang to return to the water used water quality to play the key role processing craft to include : sedimentation craft , filtration craft and chemical dosage craft, this paper researches with Total drained the sewage treatment craft of BaoGang machinery acceleration edimentation craft , filtration craft and chemical dosage craft essential technology , has confirmed the reasonablemovement parameter and the technical parameter for Total drained the sewage treatment plant of BaoGang.Regarding the mechanic acceleration sedimentation craft, this paper through to the analysis of sedimentation theory and development, as well as to Total drained the sewage coagulation sedimentation static experiment and the spot of craft contrast experiment, has verified mechanic acceleration sedimentation tank in Total drained the sewage treatment of BaoGang serviceably. And according to the mechanic acceleration sedimentation tank characteristic and the tank flowing-in condition characteristic, primarily analyzed to reform the qualitative analysis that the existing radiation flow sedimentation tank in BaoGang. For the filtration craft , this paper through to the analysis of filtration theory and filtering media application , carried on the static experiment of various kinds of filtration parameters of the porcelain filtering media and the scene industry contrast experiment, then has confirmed the porcelain sand filter which used Total drained the sewage treatment craft of BaoGang applicably , and proved including the height of filter layer , rate of filtration, control of filtration time and backwash parameter which was selected reasonably . Concerning the chemical dosage system , the thesis has given the qualitative analysis about the theoretical foundation with the chemical dosage system of " single factor " of Total drained the sewage treatment craft of BaoGang , and adjustment principle about controlling SR of setting value with chemical dosage ,and confirmed through the actual operation effect should the chemical dosage system to have the certain suitability.To the research of key technology in Total drained the sewage treatment craft of BaoGang, has offered the rational operation parameter for the fact that the production of the sewage treatment plant is operated, and guaranteed the sewage treatment system processing effect stability, provided high quality for BaoGang has returned to the water used..
