摘要

摘要: 随着我国社会经济的发展,城市初期雨水污染负荷占城市河道污染负荷比例不断增大。针对该问题,通过模拟中试试验研究了滤坝系统对城市初期雨水的净化效果。结果表明:以沸石、石灰石、海绵铁和火山岩为主要填料的滤坝系统对COD_Cr、SS、$NH_{4}^{+}$-N、TN和TP都有较好的去除效果,平均去除率分别为84.69%、89.65%、25.66%、24.46%和50.06%。滤坝系统削减污染物的主要机理是填料的物理截留和吸附、化学吸附及海绵铁的内电解反应。

Abstract: With the development of socio-economy in China, the proportion of urban initial rainwater pollution load in urban river pollution is increasing. To solve this problem, the purification effects of infiltrative dams on urban initial rainwater were investigated through pilot-scale experiment and simulation. The results showed that the infiltrative dams systems which used zeolite, limestone, sponge iron, and volcanic rocks as reactive media, had higher removal ratios of COD_Cr, SS, $NH_{4}^{+}$-N, TN, and TP, which was 84.69%, 89.65%, 25.66%, 24.46%, and 50.06%, respectively. Physical interception and chemisorption of fillers and sponge iron internal electrolysis were the main mechanisms for pollutant removal in infiltrative dams system.
