摘要
为进一步研究人工快速渗滤系统,增强其实用性,提出了采用渗透性能良好的天然砂作为主要渗滤介质,进行人工快速渗滤系统的现场试验研究,并以受污染河水为研究对象进行了为期近2a的现场试验研究.结果表明,系统的接种方式、渗滤介质的差异及运行方式对人工快速渗滤系统的污染物去除效果具有明显的影响.
Results from lab-scale experiment show that the Constructed Rapid Infiltration (CRI) system not only surmounts the shortcoming of having a low Hydraulic Loading (HL) of the traditional Rapid Infiltration (RI) system, but also reserves the advantages of the RI system. And it has a wide developing prospect. Based on the consideration of studying the CRI system in detail and strengthening its practicality, an experiment project of constructing CRI system by using natural sands is put forward. An on-site experiment has been conducted with polluted river water for about two years. The results show that the inoculation pattern, percolation medium and operation pattern have obvious effects upon the pollutant removal effect of the CRI system.
