摘要:

针对番茄茎叶自然发酵速率较慢的问题,采用与剩余污泥混合发酵(番茄茎叶与污泥挥发性固体质量比为1:2)调控底物营养结构,同时接种0.1g/mL颗粒污泥弥补体系产甲烷菌微生物不足的方法,不仅使番茄茎叶的去除率达到95%以上,而且显著提高有机物发酵的沼气产率至263mL/g(提高7.5),沼气中甲烷体积分数也相应提高至64.5%?该发酵方法不仅达到了以废治废的目的,而且实现了资源利用最大化?

Anaerobic granular sludge of 0. 1 g/ mL was inoculated to compenstaes the deficiency of methanogenesis microbes. Under such regulation, the removal rate of tomato stems and leaves was increased to more than 95 %, and the corresponding biogas yield of organie fermentation was improved to 263 mL/ g ( 7. 5 times improvement) . Meanwhile, methane volume fraction in biogas was also increased by 64.5%. This method achieves not only the goal of waste control by waste, but also that of the maximization of resource utilization
