| 摘 要： | 通过对多场降雨中pH、可沉降物、总磷、总氮、氨氮以及高锰酸盐指数的监测,分析了不同污染物质在雨水中的分布规律。分析表明,雨水呈酸性,雨水中可沉降物、总磷、总氮、氨氮以及高锰酸盐指数的浓度分别在9~245、0.038~0.250、2.83~6.25、0.11~4.90和0.70~16.00 mg/L;除pH和总氮浓度随降雨量增加变化趋势不是很明显外,其他物质的浓度随着降雨量增大而逐渐减少;初期雨水中各物质的浓度（pH除外）较高,在降雨量达8~15 mm时物质浓度趋于稳定。 |

| Abstract: | Through monitoring pH,sediment,total phosphorus,total nitrogen,ammonia nitrogen and permanganate index in rain,the distribution rule of different pollutants in rain was analyzed.The results showed that the rain was acidic.The concentration of sediment,total phosphorus,total nitrogen,ammonia nitrogen and permanganate index were 9-245,0.038-0.250,2.83-6.25,0.11-4.90 and 0.70-16.00 mg/L.The variation trend of pH value and total nitrogen concentration with the rainfall was not very clear,while the concentration of other substances decreased as the rainfall discharge increased.The initial concentration of each substance in the rain(except the pH value) was high,and tend to be steady when the rainfall discharge reached 8-15 mm. |
