摘　　要：以某造纸企业为例,对造纸废水处理过程产生的沼气进行发电综合利用,对“沼气发电+余热回收”与“沼气锅炉”两种利用方案对比分析,最终确定“发电+余热回收供汽”综合利用,比单独采用沼气锅炉产汽综合效益好,年减少碳排放量大,促进企业能源“双控”目标的实现,对企业可持续发展具有积极的推动作用。Taking a paper mill as an example,this paper comprehensively utilizes the biogas generated in the papermaking wastewater treatment process for power generation,and compares and analyzes the two utilization schemes of“biogas power generation+waste heat recovery”and“biogas boiler”,and finally determines the“power generation+waste heat recovery for steam supply”is a better way.Compared with using biogas boilers alone to produce steam,the comprehensive utilization is better,the annual reduction of carbon emissions is large,and it promotes the realization of the enterprise’s energy“dual control”goal,which has a positive role in promoting the sustainable development of the enterprise.
