摘要
分析了2013年2—12月白云湖水生态构建示范区22次水质监测数据,结果表明,水生态系统重建后,示范区各指标浓度范围为COD 15.0~26.0 mg/L,BOD53.53~15.60 mg/L,TN 0.41~3.80 mg/L,TP 0.04~0.25 mg/L,NH3-N 0.11~2.98 mg/L,与重建前相比,浓度均值依次下降了39.49%、38.17%、85.35%、72.26%、73.74%,BOD5、TN、TP由劣Ⅴ类分别改善至Ⅴ类、Ⅳ类和Ⅳ类,COD由Ⅳ类提升至Ⅲ类,NH3-N由Ⅴ类提升至Ⅱ类。
Through the analysis of 22 water quality monitoring data of ecological construction demonstration area in Baiyun Lake from February 2013 to December 2013,the results showed that concentration range of COD,BOD5,TN,TP,NH3- N were 15.0 ~ 26.0 mg /L,3.53 ~ 15.60 mg /L,0.41 ~ 3.80 mg /L,0.04 ~ 0.25 mg /L,0.11 ~2.98 mg /L respectively after ecological construction,and the average concentration of COD,BOD5,TN,TP,NH3-N were 39.49%,38.17%,85.35%,72.26%,73.74% lower respectively than before.The water quality standards of BOD5,TN,TP were improved from below class Ⅴ to class Ⅴ,class Ⅳ and class Ⅳ respectively,and COD from class Ⅳ to class Ⅲ,NH3- N from class Ⅴ to class Ⅱ.
