2016~2017年五里冲水库污染物来源调查与治理分析

Investigation and Management Analysis of the Source of Pollutants in Wulichong Reservoir from 2016 to 2017

摘要: 五里冲水库水源保护区是蒙自城区、草坝和大屯坝等地5个乡镇27万人口的主要供水地，距蒙自县城22 km，同时蒙自县是滇东南干旱缺水严重地区之一。针对2017年五里冲水库受到污染这一实际，采用水质监测方法和同年对比法从五里冲水库污染物来源方面进行分析，五里冲水库水质为Ⅳ类，污染物以氮、磷、钾为主，水库污染物主要来源于工业、农业、生活方面。五里冲水库因受到污染供水量远远不能满足蒙自的需水量，为维护水库的调解能力，不管是政府还是群众都应该采取积极的措施加以控制，才使五里冲水库的效应能充分发挥出来，水库的水量达到平衡，水循环得以进行。通过系统与部分相结合的原理对五里冲水库进行治理，以及生态保护与水质改善同时进行，恢复五里冲水库的生态功能，从而满足人们生活所需的水环境和生活环境。

Abstract: The water source protection zone of Wulichong Reservoir is one of the main water supply areas of 27,000 people in 5 towns, such as Mengzi City, Grass Dam and Datun Dam. It is one of the serious areas of drought and water shortage in the southeast of Yunnan Province. In view of the actual pollution of Wulichong Reservoir in 2017, the water quality of Wulichong Reservoir is Class IV, and the pollutants are mainly in the aspects of nitrogen, phosphorus and potassium, and the reservoir pollutants mainly come from the industrial, agricultural and domestic aspects. Both the government and the masses should take active measures to control the mediation ability of protecting the reservoir so that the effect of Wulichong reservoir can be brought into full play so that the water quantity of the reservoir reaches balance and the water circulation can be carried out. Through the principle of system and partial combination, the Wulichong Reservoir is treated, and ecological protection and water quality improvement are carried out at the same time. The ecological function of Wulichong Reservoir is restored so as to meet the need of water environment and living environment for people to live in.
