人工快渗-人工湿地工艺在河道水净化中的应用

摘要

通过人工快渗-人工湿地组合工艺处理河道水的工程案例，分析了人工快渗-人工湿地组合工艺在实际应用中对污染物的去除效果和工艺优势，结果表明该组合工艺出水水质中的COD、BOD5、NH3-N 达到《地表水环境质量标准》（GB 3838-2002）中IV类标准，TN、TP、SS达到《城镇污水处理厂污染物排放标准》（GB 18918-2002）一级A标准，不仅实现了人工快渗技术和人工湿地技术的优势互补，并且能够提高污水处理设施的视觉美感和观赏价值，改善周边环境质量。%The article analyzes the removal effect of polutants and the technological advantages of the assembled tech-nology of constructed rapid inifltration—man-made power swamp in the actual application. The result shows that COD、BOD5、NH3-N of the water quality meet IV standard of (GB 3838-2002), and TN、TP、SS meet the standard of grade one of (GB 18918-2002). It can not only realize the mutual supplement of advantage of constructed rapid inifltration technology and man-made swamp technology, but also can improve the vision aesthetic feeling and view value and improve the environmental quality around.
