  • 摘要:针对农村生活污水处理工艺多样、适应性差、决策难等问题,在系统分析北京市农村生活污水处理工艺的基础上,结合情景分析法和德尔菲法等方法,优选农村生活污水处理工艺.研究结果表明,北京市农村生活污水采用单村或联村的治理模式,处理规模集中在50(含)~500 m3·d-1,处理工艺以MBR、AO+MBR、A2O+MBR以及人工湿地等为主,逐渐由单元生物工艺向组合工艺转变、且生态工艺得到更多应用.依据处理规模和排放标准,推荐预处理+生物/生态处理、预处理+生物/生态处理+物化处理、预处理+生物处理+生态处理+物化处理等组合工艺分别适用北京市农村生活污水处理三级排放标准、二级排放标准和一级排放标准,为农村生活污水治理工作的稳步推进提供技术支撑.
  • Abstract:In response to the issues of diversification of rural domestic sewage treatment technology, poor adaptability, and difficult decision-making, this study employs Delphi method and scenarios analysis to optimize the treatment technology of rural domestic sewage based on the systematic analysis of rural domestic sewage treatment facilities in Beijing. The results show that the treatment model of single village or united village is proposed to treat rural domestic sewage, and the treatment scale is between 50 (inclusive) m3·d-1 and 500 m3·d-1. The main treatment technology is MBR, AO+MBR, A2O+MBR and constructed wetlands, which is gradually shifting from unit biological technology to combined technology, and ecological technology has more and more application in rural area of Beijing. According to the treatment scale and discharge standards, it is recommended that the combined technology of pretreatment + biological/ecological treatment, pretreatment + biological/ecological treatment + physical and chemical treatment, pretreatment + biological treatment + ecological treatment + physical and chemical treatment are presented to treat rural domestic sewage under the requirements of third-level discharge standard, second-level discharge standard and first-level discharge standard, respectively. The developed method and optimal technologies will support foe the steady advancement of rural domestic sewage treatment.
