【摘要】：通過模擬上海高架道路降雨徑流水質,基于生物滯留設施的原理設計小試和中試反應器,對比了以陶粒和沸石為介質的生物滯留設施對高架道路雨水徑流的處理條件及效果,初步討論了介質層結構對處理效果的影響。結果表明,基質強化生物滯留設施的水力負荷應不大于1m~3/(m~2·d);沸石基質對COD、TP和NH_3-N的去除效果好于陶粒,其相應去除率分別為74%、87%和71%,裝置運行期間出水水質達到《地表水環(huán)境質量標準》(GB 3838—2002)中Ⅲ類標準;沸石基質適應水力負荷范圍較大,更適于處理水力負荷變化較大的雨水徑流;添加沸石層后單位時間內污染物去除效率提高40%左右。
[Abstract]:By simulating rainfall runoff water quality of Shanghai viaduct road, a pilot and pilot reactor was designed based on the principle of biological retention facilities. The treatment conditions and effects of biologic retention facilities with ceramsite and zeolite on the runoff of elevated road Rain Water were compared. The effect of the structure of dielectric layer on the treatment effect is discussed preliminarily. The results showed that the hydraulic load of the substrate enhanced biological retention facility should not be greater than that of 1m~3/ (mt2 d);). The removal efficiency of COD,TP and NH_3-N by zeolite matrix was better than that of ceramsite, and the corresponding removal rates were 74% and 71%, respectively. The effluent quality of the plant reached the class 鈪，
