摘要

摘要: 生活污水分质收集与处理,尤其是对灰水的处理与回用可实现污水资源化利用,节约能源。介绍了生活污水分质收集基本概念和灰水水质、水量特点,重点对灰水处理技术如过滤、膜分离、MBR、人工湿地、生态滤池等的研究进展进行了综述,并对不同类型处理技术效果进行了对比分析。结果表明:单一的物理处理技术对有机物和表面活性剂等成分去除效果有限,一般需辅助其他处理技术才能达到灰水再生回用目的;化学处理技术能有效去除低强度灰水中的SS和表面活性剂;生物和生态类处理技术是目前灰水处理中应用较多的2类技术,其中人工湿地和MBR是2种较有潜力的灰水处理与回用技术。最后针对灰水处理技术研究现状,提出了未来灰水处理领域的研究重点。

Abstract: The collection and treatment of domestic wastewater by quality, especially the treatment and reuse of greywater,can realize the resource utilization of wastewater and save energy. Firstly, the basic concept of quality-based separation and collection of domestic wastewater and the characteristics of greywater quality and quantity were introduced. The research progress of greywater treatment technologies, such as filtration, membrane separation, MBR, constructed wetland, ecological filter and so on were reviewed,and the effects of different types of treatment technologies were compared and analyzed. The results showed that single physical treatment technology had limited removal effect on organic matter surfactants and other components. Generally, other treatment technologies needed to be supplemented to achieve the purpose of greywater regeneration and reuse. Chemical treatment technology could effectively remove SS and surfactants in low-intensity greywater. Biological and ecological treatment technologies were two kinds of technologies widely used in greywater treatment, among which constructed wetland and MBR were the two most potential greywater treatment and reuse technologies. Finally, according to the research status of greywater treatment technologies, the research focus in the field of graywater treatment in the future was put forward.
