Abstract:

以泥水分离机制为分类标准,现有连续流好氧颗粒污泥反应器可分为沉淀区重力沉降分离型、三相分离器型、筛网过滤分离型及膜组件分离型。总结这些研究发现,好氧颗粒污泥的连续化所取得的研究成果还极其有限,且还存在着许多不足,包括①现有连续流好氧颗粒污泥反应器的泥水分离器形式繁多,但很少有研究对泥水分离器的分离效果进行系统研究,导致难以评价这些分离器的可靠性;②缺乏对反应器内水力学流态的研究,而流态决定了微生物的存在形式及传质效果,进而影响好氧颗粒污泥的稳定性;③缺乏长期稳定运行的数据支撑,因而难以评价反应器的可靠性。对此,立足于序批式活性污泥工艺中所取得的研究成果并积极吸收工程上的成功经验与教训,无疑可大大减小连续流好氧颗粒污泥反应器研发的风险。
