摘要
再生水已经被去除了主要的污染物,但是仍然含有微量盐类(盐)、重金属(比如锌和钙)和微生物,而城市草坪是有效处理这些残留物的污水再过滤系统.草坪生物过滤是污水处理最好的过滤系统之一,亦是处理污水环境友好性最高的方式.再生水灌溉后回用不仅能充分利用水资源和草坪资源,而且可以通过草坪生物过滤与土壤含水层处理,去除污染物,提供优质中水.
Although the main pollutants in reclaimed water have been excluded, there are still some heavy metals (eg Zn and Ca) and microbes. As a filtration system, turf could exclude and treat these pollutants. Turf’s bio-filter is one of the best filtration systems available for the polluted water, and also being viewed as environmentally desirable disposal sites for effluent. Reclaimed water irrigation and recovery not only make full use of water and turf grass resources, but also serve as highly effective wastewa...
