【摘要】 以天然砂作为主要渗滤介质,建立污水处理人工快速渗滤系统(CR I)。分别以洗浴污水、生活污水和受污染河水作为研究对象,在相同的水力负荷条件下,用两种不同的运行方式(定期投配一定量的污水、淹水和落干交替运行)对不同水质的污染物去除效果进行了对比研究。结果表明,通过缩短淹水周期,加大系统淹水和落干的频率,可以明显改善CR I系统的污染物去除效果。更多还原

【Abstract】 Two lab-scales and one on-site Constructed Rapid Infiltration Systems(CRI) have been designed to treat bath wastewater,domestic wastewater and polluted river by using natural sands.At a same hydraulic loading,the removal effect of the CRI system has been studied at two quite different operation pattern(flooding and drying alternate working fashion).The results show that the removal effect of CRI is improved apparently by shortening the flooding period and increasing the flooding and drying alternate working fashion.更多还原
