厌氧消化系统过程稳定性研究和进展

Research progress and perspective on balance of anaerobic digestion system

现有常规工艺运行监控指标,对厌氧消化系统运行状况的指示性相对迟缓滞后,因而厌氧消化过程稳定性的研究受到世界各国的广泛关注。目前,厌氧消化系统过程稳定性的研究主要集中在挥发性脂肪酸(VFAs),复杂的中间代谢产物,碱度,H2的分压,酶活性,稳定性过程控制研究等方面的研究。厌氧消化过程稳定性研究的发展方向是开发出自动化,简单化,精度化,可靠化,商业化的监控技术。能够通过一些可靠,廉价的监控技术,对厌氧消化反应器进行在线监控是未来厌氧消化程稳定性研究发展的主要方向。

Indicators which are commonly used in monitoring of the anaerobic digestion process ,can not reflect the operating status in time. Therefore,the study on balance for anaerobic digestion stability has attracted wide attention all over the world. Recent studies on balance of anaerobic digestion system mainly are focused on VFAs, intermediate metabolite, alkalinity,H2 pressure, enzyme activity methanogenic coenzyme so on. Robustness, simplicity, accuracy, precision, and reliability are some of the fwrther of Anaerobic digestion process monitoring, when focusing on purchase of any of the offered technologies at the market. Simple and reliable approach can be used in online monitoring of anaerobic reactor, might be a future research direction of balance of anaerobic digestion system .
