引水河道水质生态净化工程中试研究——以嘉兴新塍塘为例

Pilot-scale Research on Water Quality-Ecological Cleaning Engineering of Diversion Channel

在嘉兴新塍塘配置人工湿地＋水下森林模式的水质生态净化系统,开展微污染源水处理效果的中试研究。结果表明,在3种不同水力负荷工况下,中试系统均可有效提高水体的SD,对水体SS、CODCr、NH3-N、TN、TP的去除率分别达74%-88%、26%-59%、84%-87%、76%-83%、36%-50%,显著改善了水体的溶氧环境。

Xinchengtang of Jiaxing was equipped with water quality-ecological cleaning system of man-made wetland ＋ underwater forest model for developing pilot-scale research on its treated effect on micro-polluted source water.The results showed that under 3 working conditions of different hydraulic loading,the pilot system could enhance SD of water body effectively and the removal rates of SS,CODCr,NH3-N,TN and TP from treated water body were up to 74%-88%,26%-59%,84%-87%,76%-83% and 36%-50% resp.and this improved the dissolved oxygen environment of water body significantly.
