摘要
我国同时面临着水资源短缺和水体污染的问题,而污水回用则可起到节水减污的双重作用,是我国解决水资源危机的重要手段。灰水是生活污水中一种不含粪尿、污染程度较低的污水,对其分类收集和处理后回用,可取得很好的环境效益及经济效益。本文将从灰水的水质、水量特点、处理技术的进展及回用的技术经济可行性等方面探讨在我国推行灰水回用的前景。
China is confronting serious problems of both water pollution and water shortage. To solve these problems, wastewater reuse is a good choice. As part of the domestic wastewater, grey water, without feces and urine, has advantages of ease to treat and reclaim. If it is treated separately and then reused, there will be a lot of benefits to both environment and economy. In this article, the characteristics and dvelopment of greywater treatment were summarized. The feasibility and perspectives of greywater reuse in China were discussed.
