Research on Treatment of Domestic Sewage with ABR Reactor-vertical Subsurface Flow Constructed Wetland
摘要/Abstract
采用厌氧折流板反应器-垂直潜流人工湿地(ABR-SSFW)组合工艺处理农村生活污水.实际运行结果表明:当水力停留时间(HRT)大于12 h时,组合工艺对COD,TN,NH3-N,TP的平均去除率分别为85.5%,42.8%,34.67%,41.97%;当HRT小于12 h时,组合工艺对COD,TN,NH3-N,TP各项的去除率都有明显下降.在对COD的去除中ABR发挥的作用较大,占到了60%以上;在对NH3-N,TN,TP的去除中,SSFW作用较大.
The combined process that anaerobic baffled reactor and subsurface flow constructed wetland(ABR-SSFW) to treatment rural domestic wastewater were studied.The actual experiment results indicate that at a HRT of above 12 h,the average removal rates of COD,TN,NH3N,TP are 85.5%,42.8%,34.67%,41.97% respectively for combined process.At a HRT of below 12 h,the removal rates of COD,TN,NH3N,TP for combined process has the obvious drop.For the remove of COD,role of ABR is larger,accounting for more than 60%.For the remove of NH3N,TN,TP vertical SSFW makes larger contribution.
