污水处理厂尾水深度处理技术的研究进展

Research of Advanced Treatment Technology of Sewage Treatment Plant Tail Water

从物化法、生物法及膜分离法等方面,对污水处理厂尾水深度处理技术进行分析。目前常用的深度处理技术为过滤、生物滤池、人工湿地、膜分离等,其中膜分离、人工湿地等技术处理效果较好。对于不同性质的尾水,应注意选择相应的深度处理技术或组合工艺。

The depth of processing on the tail water of sewage treatment plant was discussed from the physical and chemical techniques,biotechnology and membrane separation technology,etc.At present frequently used advanced treatment technologies on the depth of processing on the tail water were filter,biofilter,wetland,membrane separation and so on.The effects of membrane separation and wetland treatment were better.On different kinds of tail water,attention should be paid to select the appropriate treatment technology or combined processes.
