摘　　要：以天然砂作为主要渗滤介质处理洗浴污水的试验研究的结果表明,在相同的水力负荷条件下,采取2种明显不同的水力负荷周期运行,人工快渗系统对洗浴污水的污染物去除效果具有明显的差别,通过缩短水力负荷周期,提高了人工快渗系统的复氧效率,增大了水在系统中的停留时间,快渗系统的污染物去除效果得到了明显改善.Two lab-scale Constructed Rapid Infiltration Systems (CRI) have been designed to treat bath wastewater by using natural sands for seven months. The results show that CRI have quite different removal effect by using two different Hydraulic Loading Cycle (HLC) at the same Hydraulic Loading (HL). By shortening HLC of the system, the oxygen recovery rate is increased, the Hydraulic Residence Time (HRT) is lengthened and the removal effect is improved apparently.
