【摘要】 通过对多种絮凝剂的试验研究,筛选出UP-11混凝剂,在其投加量为2.4 mL/L时,油与COD去除效果最佳。同时在此基础上采用膜SBR法对絮凝出水做进一步处理,当运行条件为:进水0.5h、曝气4h、沉淀1h、排水0.5h时,出水完全达到国家规定的污水排放标准。更多还原

【Abstract】 Based on experimental research on various flocculants, UP-11 combined flocculant is screened. With an addition rate of 2.4 mL/L, the optimal oil and COD removing efficiency is obtained. Then, flocculation effluent is treated further by membrane SBR method. Under the condition of water inlet of 0.5h, exposed to air of 4h, precipitation of 1h and water outlet of 0.5h, the effluent will completely meet the waste water pollution standard issued by the government.更多还原
