摘　　要：通过对广州市农村生活污水治理前期工程进行调研得知,前期工程厌氧器采用的都是完全挂填料与不挂填料两种工艺。选取5个监测点进行工艺的进、出水效果监测,结果显示挂填料的厌氧器水解效果要优于不挂填料厌氧器,COD、NH3-N、TN、TP经过厌氧器(挂填料)+人工湿地后处理效率高,但完全挂填料厌氧器容易堵塞。所设计的关键技术的厌氧器水解酸化效果要优于前期农村生活污水治理中所采用的厌氧器,大大提高经厌氧器后污水的可生化性,而且采用的三个结构,可以改善完全挂填料的厌氧器堵塞情况。By rural domestic sewage treatment in Guangzhou in the early works research, there are two processes including fully linked to the filler and not linked to the filler. To select five monitoring sites, and the effect of the inlet and outlet water was monitored. The results showed that anaerobic hydrolysis effect was better, compared with not hanging filler anaerobic device. After anaerobic（hanging filler）＋artificial wetlands, the treatment efficiency was higher in COD, NH3-N, TN and TP. But it was easy to plug up stuffing anaerobic. The effect of anaerobic reactor of the key technology was better than one used in the preliminary rural domestic sewage treatment, and greatly improved the biodegradability of the wastewater. At the same time, the three structure used can improve anaerobic device completely hanging filler block.
