| 摘 要： | 以苏州官渎花园内河为研究背景,利用模拟河道分别考察了曝气复氧、人工水力循环、渗滤净化技术3种处理技术对受污河水中COD降解系数k COD、NH3-N降解系数k NH3-N变化规律的影响。实验表明,在无外源污染且河水滞留的天然情况下河道拥有一定自我净化的能力,并且3种处理技术对COD、NH3-N的降解系数都有一定提高,分别使k COD增加了34.3%、47.8%和57.8%,k NH3-N增加了8.35%、15.4%和52.8%,结果显示,渗滤净化技术对污染物降解系数的提高影响最大。

| Abstract: | Using Suzhou Guandu River as the research background and simulated watercourse as the study method,we mainly explored the effects of the aeration,artificial hydraulic circulating and infiltration purification technology on degradation coefficient of COD and NH3-N in polluted rivers. This experiment demonstrated that under natural circumstances of river detention,the watercourse had self-purification capacity without external pollution. It was found that these three treatment technologies increased kCOD by 34.3%,47.8%,57.8% and increased kNH3-N by 8.35%,15.4%,52.8%,respectively. In addition,the experimental results showed that infiltration purification technology had the best effect on the improvement of degradation coefficient of river pollutants. |
