  • 摘要: 为提高反应器的稳定性,同时对硫循环协同反硝化生物除磷(DS-EBPR)颗粒污泥和絮体污泥的脱氮除磷效果以及物质转化规律进行对比研究,实验采用序批式活性污泥反应器(SBR)分别培养DS-EBPR絮体污泥和颗粒污泥。结果表明:GSBR(颗粒污泥SBR)乙酸根平均去除率和磷平均去除率均高于FSBR(絮体污泥SBR);且GSBR中PHA(聚羟基脂肪酸)的作用机制相比于FSBR明显优于glycogen(糖原),表明GSBR具有更好的功能微生物富集作用;反应器运行过程中poly-S(聚硫颗粒)储存形式的转变表明DS-EBPR系统中poly-S的转化形式并不是根据反应阶段固定的,而是根据系统能量供需状态变化的,且对比硫循环转化效果显示GSBR的能量利用效率高于FSBR。
