洋澜湖流域污染源调查与排污特征分析

Investigation of Pollution Sources and Analysis of Pollutant Discharge Characteristics in Yanglan Lake Basin

按行政单元将洋澜湖分为5个控制单元,重点针对洋澜湖流域内各种污染源排放现状、空间分布及排放特征开展了研究,为科学制定洋澜湖综合整治方案提供决策依据,促进洋澜湖水资源可持续利用。结果表明:凤凰街办、古楼街办是洋澜湖流域主要排污单元,应在洋澜湖综合治理过程中应对这两个主要排污单元进行重点整治。洋澜湖流域污染负荷主要来源于流域范围内的城市径流污染、居民生活污染和底泥污染。

The Yanglan lake was divided into five control units by administrative division.This study focused on current situation,spatial distribution and emission characteristics of various pollution sources in the Yanglan lake basin,which provided decision-making basis for formulating the comprehensive improvement plan of Yanglan Lake scientifically and promoted the sustainable utilization of water resources of Yanglan Lake.The results showed that Fenghuang and Gulou street offices were the main pollutant discharge units in the Yanglan lake basin,and the two main pollutant discharge units as key units should be reorganized in the process of comprehensive treatment of Yanglan lake.The pollution load of Yanglan lake basin mainly came from urban runoff pollution,household pollution and sediment pollution.
