基于VS的有机固体废物厌氧消化的趋势分析

Trendency Ananlysis on Anaerobic Digestion of Organic Solid Waste with VS

在表示有机固废厌氧消化进程的三个指标(COD、TS、VS)中,VS是有代表性的指标。VS在整个厌氧消化过程中呈下降的趋势,同时,VS的变化是连续的,由此,可以用一元多项式和指数函数模型来预测有机固废厌氧消化过程中VS的变化。通过研制的混合式厌氧发酵自动控制实验装置(简称为MADACE)验证了两模型的可行性,其相关系数均达到了0.98以上。

Of the three indexes induding COD, TS and VS and which indicate the process of anaerobic digestion of orgacnic solid waste, VS is the best.VS value is decreased in the course of anaerobic digestion,meanwhile the VS change is continuous, so polynomial in one indeterminate and exponential function may show the VS change in the process of anaerobic digestion of orgacnic solid waste. The two functions are feasible by experiments with MADACE, correlation coefficients are more than 0.98.
