生物滤沟处理景观水体试验研究

Experimental Research on Biological Filtering Ditch for Scenery Water Body Treatment

提出将传统的砂石过滤与湿地塘床相结合的组合处理工艺———生物滤沟 ,并对其在常温下处理受污染城市景观水体的性能进行试验研究。试验结果表明 ,生物滤沟采用多级跌水曝气方式能有效地控制出水的嗅味。

Experimental research on biological filtering ditch (BFD), a combined process of traditional brick filtration and wetland pounds was conducted to treat urban scenery water body under normal temperature. The results show that BFD aerated by multi-stage waterfalls is effective to reduce water smell and to remove ammonia nitrogen, and also the removal of organic substances improved.
