悬浮物对源水生物预处理装置运行的影响和冲除
摘要: 探讨了悬浮物对源水生物预处理装置运行的影响程度和影响机理.中试设备模拟工程的生产条件,研究了悬浮物在填料上的积累规律,优化出适合大型源水生物预处理工程的填料冲泥方法、冲泥强度、冲泥周期等;提出了源水生物预处理装置运行时填料冲泥的判断方法. Abstract: The influence extent and reason of suspended solid (SS) on polluted raw water bio-pretreatment op eration were studied in this article. On the condition of simulating an imperial project, the accumulation characteristics of silt on the packings in the biotreatment pond was analyzed, a modified aero-water backwashing method was optimized and now used to imperial project. Finally, it is proposed that the total NH4+ -N removal efficiency, water headloss and biofilm changes can be used as references to the SS backwashing cycle of polluted raw water biotreatment running. 作 者: 陈洪斌 梅翔 高廷耀 周增炎 CHEN Hong-bin MEI Xiang GAO Ting-yao ZHOU Zeng-yan 作者单位: 陈洪斌,高廷耀,周增炎,CHEN Hong-bin,GAO Ting-yao,ZHOU Zeng-yan(同济大学环境科学与工程学院,)梅翔,MEI Xiang(南京大学环境科学与工程学院,)
