摘　　要：针对住宅小区雨水就地处理构建了浅层生态床系统,并对系统处理效果进行了试验研究。结果表明:在试验提供的参数选择中,水力停留时间5 h、填料层厚度18 cm、有复氧措施时,系统对雨水中各污染物的整体去除效果较好,出水可以达到景观回用水、排入河流等要求;床体填料层间污染物和溶解氧的平均质量浓度沿床体水平向和垂直向均递减,沿垂直向递减速率较快。The shallow ecological bed system for residential rainwater in-situ treatment was built, and the treatment effects of the system were studied. The result shows, when the parameters provided by the test were under the condition of 5 hour HRT, 18 cm filler layer thickness, and reoxygenation measures, the overall rainwater contaminants removal efficiency was better, the pollutant concentration of yielding water was met the landscape reuse water, rivers and other emissions control indicators. The average mass concentration of pollutants and dissolved oxygen （DO） between the bed filler layers were decreased along the vertical and longitudinal direction, but along the vertical direction was decreasing in faster rate.
