文摘研究了低温条件下Al 3+对好氧颗粒污泥颗粒化的强化作用.在Al 3+质量浓度为30.0mg.L-1条件下,经强化颗粒化作用的好氧颗粒污泥仅需40d即可以培养成熟,其表面光滑,结构紧密,具有较好的沉淀性能和较高的生物量.培养成熟的低温好氧颗粒污泥对污水具有较高的处理效能,COD,NH4+-N和PO34--P去除率分别达到85.6%,88.8%和91.9%,较好地实现了碳氮磷的低温高效同步去除.低温好氧颗粒污泥形成过程中,胞外聚合物中蛋白质类的质量分数明显升高,达到9.25mg.g-1,蛋白质类与多糖类的质量比(PN/PS)为1.10,说明较高含量的蛋白质类是好氧颗粒污泥形成的重要因素.同时,加入30mg.L-1 Al 3+后,污泥zeta电位从-18.40mV逐渐升高到-6.51mV,表明污泥之间静电斥力减小有利于污泥聚集,形成颗粒.
