人工湿地处理工业废水尾水的运行效果分析

Running Effect Analysis of Treating Industrial Wastewater in Yangcheng Lake Area by Constructed Wetland

为有效提升太湖水质,太湖地区城镇污水处理厂出水标准进一步提标。本文以阳澄湖地区工业废水尾水作为处理对象,运用人工湿地来深度处理尾水工程实例,研究人工湿地对尾水的处理效果的影响,结果表明:在7-9月,垂直潜流人工湿地对TN的去除效果最佳,最高达到81.0%;对CODCr去除效率最高达46.2%;进入景观湖生态净化系统后,对TN、CODCr的去除率最大分别达86.8%、50.6%。但该系统对尾水中NH3-N、TP的去除差异不明显。

In order to effectively improve the water quality of Taihu Lake,the effluent standards of urban sewage treatment plants in the Taihu Lake area have been further raised.The tail water of industrial wastewater in Yangcheng Lake area was taken as the treatment object,and an example of a deep wet water treatment project using artificial wetland was studied to study the effect of artificial wetland on the treatment effect of tail water.The removal efficiency was the best,up to 81.0%,The removal efficiency of CODCr was up to 46.2%.After entering the landscape lake ecological purification system,the removal rates of TN and CODCr were up to 86.8%and 50.6%,respectively.However,the difference in removal of NH3-N and TP in tail water by this system was not obvious.
