聚酯工艺中乙二醇废水的SBR法试验研究

SBR process of glycol wastewater in polyester technics

采用 SBR法处理乙二醇废水的实验结果表明 :废水中有机污染物得到高效的降解 .控制进水 COD在 2 50 0 mg· L-1 曝气时间 4 h、p H值在 6.5左右时 ,COD去除率平均可达96%左右 .

The experimental result of treating glycol wastewater by SBR process shows that organic pollutants in wastewater can be degraded effectively.When COD value of influent was 2 500 mg·L -1 ,aeration time was 4 h and pH value was 6.5 or so,the removal rate of COD was up to about 96%.
