Extension evaluation method and its application in waste organic gas treatment

Bio-filtering is mostly used in biological purification technology to purify low concentration waste organic gas. To improve performance of that system, the mapping relation between the process parameters and the purification efficiency must be identified, which is usually accomplished by setting up complex mathematic models between the parameters and the purification efficiency. In this paper, an extension evaluation method applying dependent function and idea of fuzzy math is proposed to evaluate the purification efficiency of the waste organic gas in the trickling bio-filter. The method is easy to be implemented by computer program and computing results prove its effectiveness.
