摘要: 利用剩余污泥在厌氧水解酸化阶段产生的高浓度有机酸作为系统内碳源, 在解决进水碳源不足的同时实现
污泥的减量,系统内碳源的使用也实现了剩余污泥的资源化利用。确定了碱解的最佳 pH 值为 10、碱解最佳的发酵时间
为 3 d 时,同时保证剩余污泥具有较高的污泥浓度时得到的水解酸化液体中富含的 VFA 较多,完全可以替代外加碳源。
结合荆马河污水处理厂运行实践,分析剩余污泥碱解发酵上清液作为污水厂内碳源的可行性。

Abstract: Sludge containing high concentrations anic acid production in the anaerobic hydrolysis acidification
phase was used as the carbon source in the system to alleviate the lack of carbon source in the inlet water and reduction of
sludge. The use of carbon source in the system had also realized the resource utilization for residual sludge. When the
alkaline pH solution was 10, fermentation time was 3 d, meanwhile ensuring a high concentration of the residual sludge, the
concentration of VFA was higher in the hydrolysis acidification liquid, which was a sufficient substitute for the external
carbon source. Combined with the oper
