City Sewage Phoredox Nitrogen And Phosphorus Removal Process

The water resources are scarce, restricts the factor which our country economy development overcomes with difficulty. Face 2lst century solutions water resources question, one is saves water, raises the water resources use factor, the solution water source lacks the water question; Two, carries on processing to each kind of origin sewage, reduces disperses into the environment the pollutant total quantity, the solution water quality lacks the water question. Carries on the denitrogenation to the sewage to eliminate the phosphorus, may reduce the water body eutrophication the occurrence, avoids some water bodies but creating the water quality as a result of the eutrophication to lack the water. In order to prevent and control day by day the serious nitrogen phosphorus pollution and the eutrophication, our country set the strict request to the city two levels of sewage treatment plants water leakage nitrogen phosphorus standard. New standing operating procedure, in cities two levels of sewage treatment plants water leakage TN<15 mg.L 1, TP<0.5mg.L 1, domestic completes at present the majority two levels of sewage treatment plants exist adapt the new standard request question, some sewage treatment plants are facing the serious transformation duty. Many dirt water works in the transformation process, both do not reduce the original handling ability, and can increase the system the denitrogenation to eliminate the phosphorus function to take a profitable target.The Phoredox denitrogenation phosphorus removal process to have the process to be stable, removes the efficiency higher merit to the organic matter, in domestic has the widespread application, but as a result of the process itself limitation, its denitrogenation eliminates the phosphorus effect to miss. This article through improves the Phoredox denitrogenation and optimizes its each movement parameter except the phosphorus process, then uses fine should east the institute the area 14, 15 female students dormitories sanitary sewage and the Pearl River beer Meizhou branch factory loads separately the waste water which the beer technological process produces to carry on slightly tries to study.This research first stage uses finely should east the institute the area 14, 15 female students dormitories sanitary sewage conduct the experimental study. The test result indicated that, eliminates the phosphorus system after the optimized Phoredox denitrogenation to have the great scope to sanitary sewage TN removing rate the enhancement,the system denitrogenation effect is satisfying; Removed the effect to TPto miss but basically had also achieved "Cities Sewage treatment plant Pollutant Discharged Standard" (GB 18918-2002) the center three levels to discharge the standard.This research second stage is introduces the beer waste water to carry on processing, by inspects this system to process other sewage denitrogenations to phosphorus removal the feasibility. The test result indicated that, eliminates the phosphorus system after the optimized Phoredox denitrogenation to have the great scope to beer waste water TN removing rate the enhancement, the system denitrogenation effect is satisfying; Removed the effect to TP to miss but had also achieved "Cities Sewage Treatment Plant Pollutant Discharged Standard" (GB 18918-2002) the center two levels to discharge the standard.The experiment indicated that, uses optimized the Phoredox process carries on processing to the sanitary sewage and the beer waste water,Can obtain the good nitrogen phosphorus to remove the effect. Through the experiment, has discussed the different movement parameter initially to the system movement effect, eliminates the phosphorus effect especially to the denitrogenation the influence, has provided the reference for the next further experimental experiment and the production experiment.
