【摘要】：通过模拟上海高架道路降雨径流水质,基于生物滞留设施的原理设计小试和中试反应器,对比了以陶粒和沸石为介质的生物滞留设施对高架道路雨水径流的处理条件及效果,初步讨论了介质层结构对处理效果的影响。结果表明,基质强化生物滞留设施的水力负荷应不大于1m~3/(m~2·d);沸石基质对COD、TP和NH_3-N的去除效果好于陶粒,其相应去除率分别为74%、87%和71%,装置运行期间出水水质达到《地表水环境质量标准》(GB 3838—2002)中Ⅲ类标准;沸石基质适应水力负荷范围较大,更适于处理水力负荷变化较大的雨水径流;添加沸石层后单位时间内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，
