摘　　要：用人工土快滤处理系统处理城市污水的实际日处理水量为６３ｍ３，年水力负荷率为２０８ｍ，ＢＯＤ５负荷为１５ｋｇ／ｍ２。试验结果表明：人工土快滤处理系统的处理效果是稳定的，其对进水ＣＯＤ、ＢＯＤ５和ＳＳ的年平均去除率分别为９０％、９６％和９５％；人工土滤床最佳进水ＣＯＤ和ＢＯＤ５浓度分别为２２０和１００ｍｇ／Ｌ；影响人工土滤池渗滤速率的主要因素有：温度、湿度和ＳＳ进水浓度等；影响人工土滤池去除率的主要因素有：温度、湿度、渗滤速率及ＣＯＤ和ＢＯＤ５的进水浓度等。The practical treatment capacity of municipal wastewater was 63 m 3/day by using artificial rapid infiltration treatment system. The hydraulic and organic loading rates (BOD 5) were 208 m/a and 15 kg/m 2·a ,respectively. Results showed that the removal effiency of ARI treatment system was stable. The removal rate of influent BOD 5, COD and SS was 96%, 90% and 95%,respectively. The artificial filter bed optimal influent concentration of COD and BOD 5 was 220 and 100 mg/L,respectively. There are many factors acting on the infiltration rate of artificial soil filter bed, including temperture, humidity, influent SS concentration etc. It was also found that these factors acting on the removal rate are temperture, humidity, infiltration rate and influent concentration of BOD 5 and COD.
