摘要
概述了饮用水厂生产废水研究的进展,根据处理工艺的不同,对比了不同处理工艺生产废水的水质特征。臭氧-生物活性炭工艺生产废水主要污染物特征为悬浮固体、有机污染物、微生物以及内源性污染物。饮用水膜法处理工艺中,超滤反冲洗水对有机物有富集作用,纳滤浓水对水中的硬度、有机污染物及新兴污染物均有富集作用。根据废水的水质特征,研究了饮用水厂生产废水回用及排放存在的问题与风险,并对已有的废水处理技术进行了综述。最后,对我国饮用水厂生产废水的处理与回用提出了一些展望。
This paper summarizes the research progress of advanced treatment wastewater in drinking water plants, and compares the water quality characteristics of different treatment processes according to different treatment processes. The main pollutants of ozone biological activated carbon process wastewater are suspended solids, organic pollutants, microorganisms and endogenous pollutants. In the membrane process of drinking water treatment, ultrafiltration backwash water can enrich organic matter, and nanofiltration concentrated water can enrich hardness, organic pollutants and emerging pollutants. According to the characteristics of wastewater quality, the problems and risks of wastewater reuse and discharge in drinking water plants were studied, and the existing wastewater treatment technologies were summarized. Finally, some prospects for the treatment and reuse of wastewater from drinking water plants in China are put forward.
