摘要
氧化沟处理城市污水或生活污水工艺运行中存在丝状菌膨胀问题。通过分析活性污泥中菌胶团细菌和丝状细菌的生理特性及动力学特征,探讨了导致低负荷氧化沟工艺中丝状菌膨胀的主要限制因子。提出低负荷氧化沟控制丝状菌过度生长的改进工艺。
At oxidation ditch treating urban sewage and domestic sewage, there exists the problem of filamentous bulking. In this paper, the physiological characteristics and kinetic features of zooglea and filamentous bacteria in activated sludge are analyzed, and the main factors causing the filamentous bulking of low rate oxidation ditch are investigated. The methods for improving the control of filamentous bulking of the oxidation ditch are proposed,and the using of chlorinate for sterilizing filamentous bacteria is introduced.
