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%。
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.
