摘要：

亲水性填料比普通填料可提高好氧处理工艺的效率2%～10%,在活性污泥法污水处理曝气池中通过添加亲水性填料,最佳污泥回流比从70%降为40%,并可以提高污水处理效率,增加处理装置的容积负荷,从而可以增加现有污水处理厂的处理能力。

Abstract:

The wastewater treatment efficiency can be increased 2% ~ 10% in aerobic treatment by hydrophilic filler. The best sludge refluxing rate is dropped from 70% to 40% in active sludge process by adding hydrophilic suspending plastic filler in active sludge tank. The adding of this filler can increase the COD_Cr load of active sludge reactor and enhance the capability of treatment also.

Key words: suspending plastic filler, wastewater treatment, hydrophilicity, active sludge process
