佛山市仙溪水库水质监测及生态修复分析

Water Quality Monitoring and Ecological Restoration Analysis of Xianxi Reservoir in Foshan

为了初步掌握仙溪水库水质变化情况,对水库进行了监测。通过在水库上、中、下游设置3个监测点,对丰水期、枯水期的水库水质进行采样与监测分析,按《地表水环境质量标准》(GB3838-2002)和《地表水环境质量评价办法(试行)》要求,结合水库周边环境及水文特点分析了仙溪水库水质基本情况。结果表明:水库氨氮浓度超标,枯水期时严重超标,应引起重视,其他指标均在可接受范围内。

Aiming to grasp the water quality change of Xianxi Reservoir, the reservoir was monitored. By setting up three monitoring points in the upper, middle and lower reaches of the reservoir, the water quality of Xianxi Reservoir is sampled and monitored during the high and low water periods. According to the requirements of “Surface Water Environmental Quality Standard”(GB3838-2002) and “Surface Water Environmental Quality Assessment Method (Trial Implementation)”, the basic situation of water quality of Xianxi Reservoir is analyzed in combination with the surrounding environment and hydrological characteristics of the reservoir. The results show that the concentration of ammonia nitrogen in the reservoir exceeds the standard, and seriously exceeds the standard in dry season, which should be paid attention to. Other indicators are acceptable.
