| 中文摘要: |
| 饮用水系统中以胶体态赋存的新污染物具有较强的吸附性和迁移性,容易造成饮用水复合污染。针对胶体态新污染物的概念、在水源水中的赋存特征、饮用水处理系统的去除现状以及在饮用水输配系统中的迁移规律这四个方面的研究进展进行综述。总结发现,水源水中的新污染物容易相互吸附或被其他天然胶体态物质吸附,从而影响彼此的赋存和迁移。传统处理工艺对胶体态新污染物的去除能力有限,高级处理工艺可高效去除胶体态新污染物,但新污染物以胶体态赋存时会影响各工艺的去除效果。未被去除的部分胶体态新污染物会通过供水管网迁移至龙头水,而另一部分则会沉积在管网中。最后,展望了饮用水系统中胶体态新污染物的筛查监测、风险评估和防控治理,以期为饮用水污染控制提供技术参考。 |
| 英文摘要: |
| Colloidal emerging contaminants in drinking water systems have strong adsorption and transport properties, which can easily cause compound contamination of drinking water. This paper reviewed the research progress in four aspects: the concept of colloidal emerging contaminants, their occurrence characteristics in source water, their current status of removal by drinking water treatment system, and their transport pattern in drinking water distribution system. It is summarized that emerging contaminants in source water tend to adsorb to each other or to other natural colloids, thus affecting each other"s occurrence and transport. Conventional treatment processes have limited ability to remove colloidal emerging contaminants, and advanced treatment processes can efficiently remove colloidal emerging contaminants, but the presence of emerging contaminants in colloidal state will affect the removal effect of each process. Part of the colloidal emerging contaminants that are not removed transport to the tap water through water supply network, while the other part deposit in the pipe network. Finally, this review prospected the screening, monitoring, risk assessment, prevention, control and treatment of colloidal emerging contaminants in drinking water systems, with a view to providing technical references for the control of drinking water pollution. |
