中文摘要:
      以安徽建筑大学南校区为例,研究合肥市校园绿地对自然降水水质净化以及自然降水对校内人工湖水质的影响。SS、COD、TN、TP等污染物指标数据显示:校园绿地对于污染物指标去除率分别为:47%、50%、16%、51%;其中在降水径流产生20min内去除效率最高,在120min后污染物指标含量变化趋于稳定。降雨前后校园人工湖的水质数据结果显示:降水后湖中SS、COD、TP浓度变大,TN浓度变化不大,由此可知,初期降水的污染物是造成水体非点源污染重要因素。
英文摘要:
      Take South Campus of Anhui Jianzhu University as an example, to explore the campus green space in Hefei City on natural rainfall water quality and the influence of natural precipitation for the campus artificial lake water quality. SS, COD, TN and TP were analyzed and compared, the removal rate of pollutant indexes in green space were: 47%, 50%, 16%, 51%; and the highest removal efficiency was rainfall-runoff producing within 20 minutes, change tend to be stable after 120 minutes. The campus artificial lake water quality data before and after rainfall shows that the concentration of SS, COD, TP increased considerably but TN changed little. Therefore, pollutants in the early rain is the important factor which caused non-point source pollution of the water.
