组合湿地塘调蓄净化技术中试研究

Pilot Scale Study on Combined Wetland and Storage Pond Purification Technology

针对用于工业区雨源型河道生态补水的调蓄水的水质维持与净化,研发了“植物强化稳定塘-强化人工湿地”组合工艺,建立一套20m3/h规模的中试装置。研究表明,组合湿地塘调蓄净化技术中试系统对COD、NH4+-N、TN、TP、SS分别有14.13%~31.99%、33.64%~77.42%、24.72%~48.04%、61.29%~67.20%、45.44%~76.90%的去除率。

For the water quality maintenance and purification for the ecological water replenishment in the rain source river of industrial park,a combined process of“plant stabilization ponds-enhanced constructed wetland”was developed.The scale of pilot plant was 20 m3/h.The research showed that the combined wetland and storage pond purification technology had a significant removal rate of COD,NH4+-N,TN,TP,SS of 14.13%~31.99%、33.64%~77.42%、24.72%~48.04%、61.29%~67.20%、45.44%~76.90%.
