- 摘要:
- 综合分析了生物垃圾厌氧消化的各种强化技术与机理.由于传统化石燃料的枯竭和造成的生态环境问题，清洁再生能源的生物气体日益受到人们的青睐.但是，消化时间长，产气量较低，垃圾利用率不高等原因，导致生物垃圾厌氧发酵技术没有得到充分的开发与推广.研究认为，通过强化处理能够改善生物垃圾的物化性质，提高微生物对难降解有机物的分解能力，增加生物气产量，缩短水力停留时间，减轻后续处理的负担，优化垃圾厌氧消化过程.
- Abstract:
- Biogas,a clean and renewable form of energy could very well substitute for conventional sources of energy(fossil fuels,oil,etc.) which are causing ecological-environmental problems and at the same time depleting at a faster rate.Despite its numerous advantages,the potential of biogas technology could not be fully harnessed or tapped as certain constraints are also associated with it.Most common among these are: the large hydraulic retention time,low gas production,etc.Therefore,efforts are needed to remove its various limitations so as to popularize this technology.Researchers have tried different techniques to optimize anaerobic process,enhance gas production,reduce hydraulic retention time(HRT) and release post-treatment.The authors review the various techniques,which could be used to enhance the gas production rate from biowastes.
