水污染调查贡献率源解析Water Pollution Investigation Contribution Source Apportionment

摘要:

流域源解析可为水环境综合整治提供依据。本文采用调查和数学模型估算溧阳重点流域内点源和面源的典型水污染物的排放量和贡献率。结果显示,渔业养殖、种植农村生活污水和污水厂是溧阳主要的水污染源。工业排放的污染物虽然贡献率较小,但是从2011到2013有逐年增加的趋势。种植业的总氮、总磷排放量分别占溧阳排放总量的46.24%和46.88%。渔业养殖排放的COD、总磷分别占溧阳排放总量的26.01%和40.83%,且排放贡献率有增加的趋势。点污染源排放的COD、氨氮、总氮、总磷的贡献率分别为37.12%,44.02%,21.30%和7.63%,而面源的相应污染物的贡献率分别为62.88%,55.98%,78.70%和92.37%。对面源的管理控制措施是溧阳水环境整治的重点。

Source apportionment can provide the basis for comprehensive improvement of water environment. Based on the investigation and mathematical model, this paper estimated water pollutants emission and contribution from point source and non-point source in the key rivers of Liyang city. The results show that: the fishery, rural domestic sewage and city sewage treatment plant are the main water pollutant sources. The contribution of water pollutants from industrial emission source is small and the water pollutants emission from is increased from 2011 to 2013. The loss of the total nitrogen and total phosphorus from farmland accounted for 46.24% and 46.88% respectively. The loss of COD and total phosphorus from fishery accounted for 26.01% and 40.83% respectively and the pollutant contribution kept increasing. The contribution of COD, ammonia nitrogen, total nitrogen and total phosphorus from point source is 37.12%, 44.02%, 21.30% and 7.63%, and from non-point source is 62.88%, 55.98%, 78.70% and 92.37%, respectively. As a result, the management of non-point source is more important than that of point source.
