【摘要】 论述再生水水质特性及回补景观水体产生的问题,综述再生补给型景观水体水质维护措施。以北京潮白河为例,分析了再生水回用所产生的水质问题及其改善措施的效果。结果表明:再生水进入河道后,有机污染和叶绿素浓度上升,藻类大量繁殖,河道水体表现出明显的富营养化趋势;但水质改善工程措施可明显降低N、P等营养元素浓度,改善水质。更多还原

【Abstract】 The water quality characteristics and the problems of reclaimed water reusing as scenic water were discussed,and some improvement measures were summarized for the reuse of reclaimed water.With ChaoBai River as an example,the water quality problems of the reclaimed water and the effects of the improvement measures were analyzed.The results showed that the concentrations of COD and Chlorophyll a went up obviously while algae grew up abundantly after the reclaimed water entered into river,and the river showed the trend of eutrophication.However,the improvement measures could reduce the concentrations of N and P and improved the water quality.更多还原
