摘要
[目的]探讨水生态修复技术在徐州小沿河水源地保护中的应用效果。[方法]根据2012年监测资料,对徐州市小沿河水源地水生态修复工程措施的修复能力及效果进行分析评价。[结果]如果用去除率表示,修复工程对高锰酸盐指数(COD_(Mn))、氨氮(NH_4-N)和总磷(TP)的修复能力分别大于等于41.57%、79.49%和71.18%。修复工程实施后,综合水质类别由原来的Ⅳ类提升为Ⅲ类。[结论]水生态修复工程对水源地水质具有明显的提升作用。
[Objective] The aim was to explore the application of water ecological restoration technology in protection of Xiaoyanhe water source in Xuzhou. [Method]On the basis of the monitoring data of 2012,the restoration capacity and restoration effect of water ecological restoration system of Xiaoyanhe water source in Xuzhou were evaluated. [Result] If represented using decreasing rate,the restoration capacity to COD（Mn）,NH4-N and TP was greater than or equal to 41.57%,79.49% and 71.18%,respectively. Water quality was improved from level Ⅳ to level Ⅲ. [Conclusion] The application of water ecological restoration system can significantly improve water quality.
