摘　　要：山东省一中药企业污水处理厂日产沼气量4000 m^(3),经热解处理达标后对空排放,造成了资源浪费。对沼气进行回收再利用,可达到污染防治、能源回收与资源再生综合利用的目的,实现经济、社会、生态效益相统一。通过对3种沼气回收再利用技术路线及预期效益进行探究分析,得出沼气锅炉供热技术路线工艺从经济性和适用性方面而言要优于其他2种工艺,年利润达1.969×10^(6)元,项目静态投资回收期最短。A traditional Chinese medicine enterprise sewage treatment plant in Shandong Province produces 4000 m^(3)of biogas daily,which is discharged to air after pyrolysis treatment to meet the standard,resulting in waste of resources.The recycling of biogas can achieve the purpose of pollution prevention,energy recovery and resource regeneration,and realize the unification of economic,social and ecological benefits.By exploring and analyzing three biogas recovery and reuse technical routes and expected benefits,the biogas boiler heating technology route process is better than the other two processes in terms of economy and applicability,with an annual profit of 1.969×10^(6)yuan and the shortest static investment payback period of the project.
