洨河湿地水质变化分析
|
摘要
[目的]选取洨河人工湿地为研究对象,开展水体流经湿地后水质指标变化分析。[方法]分析从湿地入口至出口之间河段的pH、COD、NH_3-N、TN、TP的沿程变化。[结果]水体经过人工湿地后,pH相对稳定,湿地对水中主要污染物COD、NH_3-N、TN、TP的降解效果明显,但TN、TP仍维持在较高的水平,应通过生物调控技术完善湿地水体生态系统,进一步增加生态修复措施,降低河道发生水体富营养化的风险。[结论]经水质评价,湿地出口处水质达到了Ⅱ类,说明人工湿地对于改善水质状况有着明显的作用。
[Objective]Xiao River artificial wetland was selected as the research object to analyze the change of water quality index after the water body flows through the wetland.[Method]The changes of pH,COD,NH_3-N,TN and TP of the river section from the inlet to the outlet of the wetland were analyzed.[Result]After the wetland,the pH would appear relatively stable,the degradation of COD,NH_3-N,TN and TP was obvious,but TN and TP were still at a high level.Biological regulation technology should be taken to improve wetland water ecosystem,to increase ecological restoration measures to reduce the risk of eutrophication of water bodies in rivers.[Conclusion]After water quality evaluation,the water quality of the wetland outlet reached Class II,which also shows that constructed wetlands have a significant role in improving water quality.
