化学混凝强化 SBR工艺除磷的试验研究
Experimental Research on Phosphorus Removal by Enhanced SBR Process Assisted with Chemical Coagulation
摘要
Abstract
Chemical coagulation and SBR process were used to investigate phosphorus removal effects of chemical and biochemical synergy and the influences when changing pH and temperature. In the experiment,synthetic municipal wastewater was treated,and two different coagulants,ferric chloride and aluminum sulfate,were chosen. The results show that the average dosage of ferric chloride is 17. 18 mg/ mg TP,and it has a good synergistic effect with the activated sludge;aluminum sulfate’s is 27. 12 mg/ mg TP,and it has no synergistic effect. Besides,the two coagulants can significantly strengthen the effect of phosphorus removal. In the biochemical reactors,maintaining an alkalescent environment and an appropriate temperature range of 15 ~ 25 ℃ is propitious to nitrogen and phosphorus removal.关键词
