东昌湖污染源解析与防治对策

Sources of Pollution Survey and Water Quality Analysis for Dongchang Lake

采用资料收集、电话咨询、实地走访与室内分析相结合的方法,对东昌湖潜在污染源进行了排查,发现1#湖区花生米加工厂、肉食作坊及3号湖区区政协排污口是东昌湖仅有的三个污染源。通过等标污染负荷及污染负荷比计算分析,得出区政协排污口对东昌湖水质影响最大,其次为花生米加工厂和肉食作坊。从三个污染源排放的污染物来看,CODCr及TP的污染负荷最大,氨氮最小。针对东昌湖污染源现状,提出了东昌湖水环境污染防治的对策和建议。

Through investigating potential pollution sources of Dongchang Lake by data collection, telephone interviews, site visits and laboratory analysis, peanut factory in NO.1 lake district, meat workshop and District Political Consultative Conference outfall in NO.3 lake district were confirmed the three sources of pollution affecting the water quality of Dongchang Lake. On the basis of the equivalent standard pollution load and pollution load ratio of pollution sources and pollutants, the results showed below： District Political Consultative Conference outfall had the greatest impact on the water quality of Dongchang Lake, the next were peanut factory and meat workshop. From the three pollution indicators, CODCr and TP had the maximum pollution load, Ammonia had the minimum pollution load. Aimed at the pollution sources situation of Dongchang Lake, water pollution prevention countermeasures were put forward.
