| 摘 要： | 本文在简要描述活性污泥处理过程中有机物降解及微生物增长对营养的需求的基础上,对由痕量金属缺乏症引起的污泥丝状菌膨胀问题进行了分析,说明了在处理过程中生长速率缓慢的丝状菌大量繁殖,而生长速率快速的絮凝微生物受到抑制的原因。本文还介绍了用补充痕量金属的方法成功地控制丝状性污泥膨胀的几个实例。

| Abstract: | Based on the nutrient requirements for the growth of microorganisms inactivated sludge treatment process, this paper analysed that sludge bulking caused by trace metal deficiency, and the reasons why slow-growing filamentous microbes predominated over faster-growing flocculent microbes, It also gave Some successful control practices of treating filamentous sludge bu king by adding prepared trace metal salt solutionsto the treatment system. |
