摘　　要：分析了乌鲁木齐市河东污水处理厂原有污泥厌氧消化池工艺(已停产)存在的问题,采用污泥浓缩/中温厌氧消化/脱水/干化/土地利用工艺进行改造。改造后的污泥厌氧消化池调试运行效果较好,该工艺产生的大量热水可以作为消化池加温的热源,生成的沼气用来发电,可以满足污水厂及附近生活区日常用电需要。Several problems of the original sludge anaerobic digestion tank process of the Hedong Sewage Treatment Plant in Urumqi were analyzed. The technological reconstruction of the anaerobic digestion tank was performed using sludge thickening/mesophilic anaerobic digestion/drying/land use process. The commissioning effect of the reconstructed sludge anaerobic digestion tank was good. The massive hot water produced by the process can be used as the heat source for the digester, and the methane gas produced can be used for power generation to meet the daily electricity needs of the sewage treatment plant and the surrounding areas.
