摘　　要：文章根据青岛一个污水厂现有污泥中温厌氧发酵沼气热电联产系统,计算得出污泥高温厌氧发酵时相关数据,设计采取太阳能-高温水源热泵供热的方案补充热量,对污泥高温厌氧发酵系统进行综合评价。结果表明:1)污泥高温厌氧发酵系统较污泥中温厌氧发酵系统产气量多,净发电量大,系统需热负荷大;2)采用沼气+太阳能供热系统为污泥供热,可充分利用太阳能以及回收中水热能,加热循环水,减少一次能源的消耗量;3)污泥高温厌氧发酵系统与污泥中温厌氧发酵系统相比,年电费收益略小,环境效益较大。In this paper,based on a existing sludge anaerobic fermentation system with combined heat and power cogeneration under mesophilic condition in a sewage plant in Qingdao,the relevant data for sludge anaerobic fermentation under thermophilic condition were calculated,and a thermophilic anaerobic system was designed with a solar energy-high temperature water heat pump for heat supplement,and was evaluated comprehensively. The results showed that： 1） the sludge produced more biogas under thermophilic condition than that under mesophilic condition; 2） the system could make full use of solar energy and recycle the water heat; 3） it had smaller annual electricity benefit with higher environmental benefits comparing with the mesophilic system.
