CSTR和PSA工艺在规模化生物天然气项目中的应用
The Application of CSTR and PSA Technology in Large-scale Biogas Project
摘要
Abstract
In order to explore the applicability of German CSTR and PSA technology in large-scale biogas project in China,the biogas production characteristics,process stability and the effects of Organic load rate(OLR)on biogas production and microbial community structure were studied.The results show that the technology is suitable for large-scale biogas project in China.The methane volume fraction of biogas fluctuates between 55.38％and 75.79％,with an average value of 67.20％.After purification,it stabilized above 98％(98.34％±0.15％).With the increase of OLR,the average biogas yield and volumetric biogas yield increased significantly(37.8％),while the average TS biogas yield decreased by 6.8％.The abundance of Chloroflexi and Bacterodota decreased significantly,while the abundance of Patescibacteria increased by nearly 2 times.The abundance of Proteiniphilum,HN-HF0106,Syntrophomonas,Fastidiosipila and unclassified_Erysipe-lotrichaceae decreased at the OLR decrease,while the abundance of Caldicoprobacter increased at the OLR increase.The abundance of Acetotrophic and Hydrogenotrophic methanogens Methanosarcina decreased from 73.3％to 46.7％,the a-bundance of Hydrogenotrophic methanogens Methanoculleus increased from 2.8％to 46.7％,and the abundance of Meth-ylotrophic methanogens Methanomassiliicoccus increased from 2.5％to 27.5％.关键词
