摘　　要：提出了异波折板多段两相厌氧城市污水处理工艺。通过反应器内异波折板的结构设计、液相流速设计和系统内生物相的分段调控,在提高传质效率的同时,使不同种群微生物的生化活性得到明显改善,有机污染物去除效率显著提高。实验结果表明,当水力停留时间大于10 h时,COD的去除率可达90%以上,而且受温度影响很小。The authors put forward a technical process to treat municipal wastewater using multistage two-phase anaerobic reactor, which not only increases the efficiency of mass transfer but also improves the biochemical activity of different kinds of microbe, and thereby greatly increases the efficiency of organic pollutants treatment through the design of anaerobic baffled reactor structure, flow velocity and multi-stage regulation of microbe. The experiment results show that when hydraulic residence time longer than 10 h is used, the removal rate of COD is above 90% and less affected by water temperature.
