摘　　要：本文将生物-生态水体修复技术引入护岸结构,设计了净水箱护岸结构,该结构充分利用了河道排污管所在岸坡具有一定坡度和落差的特点,只需对原有小而分散的沿河排污管道进行简单改造,将污水布入净水箱护岸结构即可。现场试验表明,尽管累计水力停留时间仅为2h,但系统对初期径流污水中的监测污染物去除率都在40%以上;截留后的雨水仅在净水箱中停留5d,相对进水浓度而言的监测污染物累计去除率都在75%以上。该结构净化污水效果好,整洁美观,运行成本低,维护简单,不占用土地,在我国有较高的推广应用价值。The paper presents a structure of water purifying box in which the bio-ecology rehabilitation technology is adopted in urban fiver revetment. By making best use of bank slope and its fall where polluted water pipes are laid, a simple modification is carried out by loading polluted water into the water purifying box revetment. A series of on-site tests were conducted and the results show that the removal ratio of the pollutants from the device is over 40% with its hydraulic retention time of 2h. After 5d of water retaining in the box, the cumulated pollutant removal ratio would be higher than 75 %. With the advantages of excellent water purifying performance, good landscape effect, low running cost, simple maintenance and no land occupation, this structure will be widely applied in China.
