【摘要】 根据仿生学的理论,和自然界恢复能力与自净能力的强化作用,对农村传统的污水处理设施进行合理改善,构建人工土壤渗滤-湿地系统。通过试验,对系统的去除机理和组合优点进行了有益的探索;经过长期的稳定运行,表明即使在进水浓度较高的情况下,系统COD、BOD5去除率分别为70%～90%、70%～80%,TN、NH4+的去除率分别达到70%～95%、80%～95%。更多还原

【Abstract】 According to the theory of bionics and the strengthening action of natural recovering ability and self-purifying ability,the rural traditional sewage treatment utilities was improved reasonably,and an artificial soil infiltration-constructed wetland system was established for the rural sewage treatment.Through a test,the present authors made a beneficial inquiry into the system’s removal mechanism and combined process’s advantages.It was shown that,through long-term and stable operation,the system’s removal rate of COD,BOD5,TN and NH4+ reached to 70%～90%,70%～80%,70%～95% and 80%～95% respectively even though their influent concentration were higher.更多还原
