摘要: 采用3组构造一致的完全混合流态水解酸化反应器,分别以同等浓度的絮凝污泥、初沉污泥和剩余污泥作为底物污泥,在温度35℃,初始pH=10的反应条件下,研究污泥性质的差异对污泥水解酸化产物及产率的影响。实验结果表明:与初沉污泥、剩余污泥相比,絮凝污泥更易水解产酸发酵,至第9天水解产SCOD达到最大值2 713.2 mg/L,第7天酸化产VFAs达到峰值1 392.7 mg/L。3种污泥酸化产VFAs的主要组分均为乙酸和丙酸,但絮凝污泥VFAs组分中乙酸、丙酸这种优势更加明显,其所占比例分别高达48.9%和27.2%。此外,3种污泥水解酸化产碳源的同时均伴随着氮、磷元素的释放,整体而言,絮凝污泥产酸发酵中氮、磷元素的释放量及释放率均较低。

Abstract: The effect of sludge property on the sludge hydrolysis and acidification was investigated through applying three configuration-consistent and completely mixed pattern of hydrolysis acidification reactors. The three reactors were fed with flocculation sludge, primary sludge and excess sludge with the same contents, respectively. The experiments were performed under the condition of 35℃ and initial pH=10. The results show that flocculation sludge is easier to be hydrolysed and fermented to produce acids compared with the primary and excess sludges. After 7 days hydrolysis and acidification, about 1 392.7 mg/L VFAs are produced and peaked. And after 9 days reaction, the maximum SCOD production with 2 713.2 mg/L are produced. For all the three types of sludge, acetic and propionic acids are the main components in VFAs. The fractions of acetic and propionic acids are more higher using the flocculation sludge than those using other sludges. Their proportions can achieve 48.9% and 27.2% using the flocculation sludge, respectively. In addition, the release of nitrogen and phosphorus in the three types of sludge are accompanied with the sludge hydrolysis and acidification. And the flocculation sludge has lower release amount and rate for nitrogen and phosphorus in the fermentation process.
