草邦水库水质现状评价与污染防治措施

The Water Quality Assessment and Pollution Prevention Measures of Caobang Reservoir

以草邦水库水质现状监测为基础，评价其水质现状．监测结果表明，草邦水库在枯水期的总P质量浓度为0．087-0．129mg·L^-1，总N质量浓度为0．719-1．158mg·L^-1，高锰酸钾质量浓度为5.261-7．824mg·L^-1，表明水库水质具有富营养化现象；其它监测项目均在GB3838-2002《地表水环境质量标准》Ⅲ类标准之内．建议在控制污染源的同时，应从生态等方面加强对草邦水库的管理．

The present state of water quality of Caobang reservoir was analyzed and assessed on the basis of the results from monitoring the present state of reservoir. As indicated by monitoring results, total phosphates , total nitrogen and CODMn attain the concentration of 0. 087-0. 129 mg·L^-1, 0. 719-1. 158 mg·L^-1 and 5. 261-7. 824 mg·L^-1 respectively in the low water season of Caobang reservoir, indicating the phenomenon of eutrophication. Other terms of monitoring were within Ⅱ order water quality standard for surface water. According to the assessed results. The best counter measures to protect the water quality were pollution control and ecolgical management enhancement.
