Abstract:

The application of biofiltration as final process to slightly-polluted water treatment is an economical and effective way to achieve organic pollutant removal and turbidity removal within the same filter unit. Further study has been conducted to evaluate the performance of biofiltration in removing organisms, NH4+ - N and turbiditythrough pilot-plant experiments. Results show that biofiltration can remove the organic matters as well as NH4+ - N effectively, and the effluent turbidity of biofiltration can maintain as low as that of traditional filtration.

Key words: slightly-polluted water, biofiltration, organic matter

摘要：

以生物过滤作为微污染水处理的末级处理工艺,可使有机污染物和浊度的去除在同一滤层内实现,是一种经济、有效的生物处理方法。作者通过模型试验,深入探讨了生物过滤对微污染水中有机物、氨氮、浊度等的去除效果。试验结果表明:生物过滤能够有效地去除微污染水中的有机物、氨氮等物质,同时能够获得与常规过滤一样低的出水浊度。
