摘要
研究了中和混凝-厌氧十好氧-生物活性炭组合工艺，在不同工况和运行参数条件下处理聚醚废水的效果．结果表明，中和混凝能有效地降低生物处理的污泥负荷，调节pH值6．7，聚合氯化铝的投加量为l00mg/L时．聚醚废水COD去除率可达28％，当进水的COD为3000～4000mg/L时，聚醚废水经此组合工艺处理后，COD的总去除率达96％以上，出水COD值约150mg/L.
The feasibility and effeCt of applying cogulation-sedimention - anaerobic +aerobic biologle al active carbonprocess to treat Polyaether wastewater in different operating conditions was studied. The resultS showed cogulationsedimtion process could efficiently reduce the sludge loading rate of biological treatment process. when PAC was usedwith 100lug/L at PH 6.7, COD removal rate can reach 28%. Applying the above treatment process,when COD of influentis about 3000～4000mg/L, COD of effluent can reach about 150mg/L and total COD removal rate is more than 96%.
