温岭市湖漫水库水质状况与污染防治对策分析
|
摘要
基于温岭市湖漫水库2011年～2017年水质监测数据,分析了库区水质变化情况,污染来源和环境容量。结果表明:该水库水质在2011年～2016年达到《地表水环境质量标准》(GB3838-2002)Ⅱ类水质标准限值要求,2017年水质劣于Ⅱ类水标准限值,主要超标因子为高锰酸盐指数、总氮、总磷;入库污染源贡献情况为农业种植面源>地表径流污染源>居民生活源,入库污染源COD、总氮、总磷总量分别为161.55 t/a、82.3 t/a、5.56 t/a,而库区总氮和总磷环境容量估算值分别为74.41 t/a和5.25 t/a。为持续削减入库污染负荷并保障饮用水安全,从产业结构调整、污染防治、生态修复、环境监管能力建设等四个方面提出了防治对策。
Based on monitored water quality data of Human Reservoir in Wenling City between 2011 and 2017, change of water quality, pollution source and water environmental capacity were analyzed. The results showed that water in this reservoir satisfied the requirements of Class II water quality standard in environmental quality standard for surface water(GB3838-2002) from 2011 to 2016. In 2017, water in this reservoir was worse than the standard due to high CODMn, total nitrogen and total phosphorus. Pollution source order from high to low was agriculture, surface runoff and residents. The amounts of COD, total nitrogen and total phosphorus into the reservoir were 161.55 t/a, 82.3 t/a and 5.56 t/a. The environmental capacities of total nitrogen and total phosphorus were estimated to be 74.41 t/a and 5.25 t/a. In order to reduce the pollution load into the reservoir and ensure drinking water safety, measures were put forward from the aspects of industrial structure adjustment, pollution prevention and control, ecological restoration and environmental supervision.
