摘要
污泥厌氧发酵不仅可以产生短链脂肪酸补充污水脱氮除磷工艺中碳源的不足,还可以实现污泥的减量化和资源化。该文综述了温度对污泥厌氧发酵产酸影响的研究进展,着重讨论了温度对污泥厌氧发酵过程中水解、短链脂肪酸(SCFAs)累积、甲烷的产生和污泥减量化等方面的影响,并对今后的研究方向进行了展望。
The use of short chain fatty acids (SCFAs)-richened fermentation liquid as the additional carbon source of biological nu- trient removal (BNR) has been considered as a practical and sustainable solution for increasing BNR performance, by which both waste bio-solids utilization and internal carbon source production can be accomplished in the biological wastewater treatment plants. According to the latest research, the sludge anaerobic fermentations under different temperatures were reviewed in this paper. The ef- fect of temperature on hydrolysis, acidification, methane production and sludge reduce was discussed in details in this paper. The re- search direction in the future was put forward.
