剩余污泥与秸秆发酵产酸研究进展
|
摘要
随着我国经济的迅猛发展,人们生活水平的提高,所产生的废物量日益增多。目前利用污泥和秸秆作为碳源发酵产酸是一种变废为宝的处理方式。研究表明,发酵前对污泥与秸秆进行适当的处理,可以使有机质的溶出量增大,从而增加VFA的产量。而从发酵产酸的机理入手,研究其产酸的过程,有利于人为调控发酵参数使得VFA的产出量增加。
with the rapid development of China's economy and the improvement of people's living standards, the amount of waste produced is increasing. At present, the use of sludge and straw as carbon source fermentation to produce acid is a waste disposal method, and how to maximize the production of VFA? The results showed that proper treatment of sludge and straw before fermentation could increase the amount of dissolved organic matter and increase the yield of VFA. Starting from the mechanism of acid production by fermentation, the study on the process of acid production is conducive to the artificial regulation of fermentation parameters to increase the output of VFA.
