摘　　要：采用间歇曝气一体化悬浮填料床/垂直流人工湿地组合工艺处理农村生活污水,考察了工艺的运行效果及各处理单元对去除污染物的贡献率。试验结果表明,该组合工艺对污染物具有较好的去除效果,且处理效果很稳定,对COD_(Cr)、NH_(4)^(+)-N、TN、TP的去除率分别为97.49%.100%.88.18%、96.09%。间歇曝气一体化悬浮填料床对去除COD_(Cr)、NH_(4)^(+)-N、TN的贡献率较大,对去除TP的贡献率相对较小;人工湿地对去除TP的贡献率较大,对去除COD_(Cr)、NH_(4)^(+)-N、TN的贡献率相对较小。间歇曝气一体化悬浮填料床与人工湿地相结合可以发挥两者的优势,并提高出水水质和系统运行的稳定性。combined process of intermittent aeration integrated suspended packed bed/vertical flow constructed wetland was used to treat rural domestic sewage.The operation effect of the process and the contribution rate of each treatment unit to the removal of pollutants were investigated.The experimental results show that the combined process has a good removal effect on pollutants,and the treatment effect is very stable.The removal rates of COD_(Cr),NH_(4)^(+)TN and TP are 97.49%,100%,88.18%and 96.09%respectively.Intermittent aeration integrated suspended packed bed has a large contribution rate to the removal of COD_(Cr),NH_(4)^(+)-N and TN,and a relatively small contribution rate to the removal of TP;The constructed wetland has a large contribution rate to the removal of TP and a relatively small contribution rate to the removal of COD_(Cr)NH_(4)^(+)-N and TN.The combination of intermittent aeration integrated suspended packed bed and constructed wetland can give full play to their advantages and improve the effluent quality and the stability of system operation.
