不同源水和回用途径的再生水处理工艺的选择

Selection of Reclaimed Water Treatment Processes under Different Source Water Qualities and Reuse Approaches

基于我国再生水的实际应用情况,针对不同源水水质和不同回用途径对再生水处理工艺的要求,分析比较了不同类型回用水水质与城镇污水处理厂出水水质的差异,并根据实际应用情况进行了再生水处理工艺的选择和推荐。同时,从进水水质要求、工艺选择、不同回用途径之间的协调及工艺发展等方面对再生水回用提出了相应建议,以期为我国再生水处理工艺的选择提供借鉴。

The reclaimed water treatment process should be chosen under different source water qualities and different reuse approaches. The water quality difference of different kinds of reclaimed water and municipal wastewater treatment plant＇ s effluent were analyzed and compared, meanwhile, the suit- able reclaimed water treatment processes were selected and recommended. The corresponding suggestions for reclaimed water reuse were made, including influent quality requirement, process selection, harmoni- zation among different reuse approaches and process development to provide reference for selecting appro- priate treatment process of reclaimed water.
