摘要
针对脱墨废水处理沉淀池发生污泥上浮现象,从温度、pH值、致毒性底物、食微比、溶解氧等因素进行分析,得出曝气量过大污泥会被打得又轻又碎,引起污泥上浮。提出了减小曝气量、增大营养盐投加比等有效的解决措施。
In order to solve the floating sludge phenomenon happens in sedimentation, this article analyzes the factors such as temperaturc,pH,the toxic substrate, food micro-ratio, dissolved oxygen and so on, then get the conclusion that large sludge will be lighten and broken by excessive aeration. At last the article proposed the solutions like reducing the air flow rate, increasing nutrient dosage ratio and other effective measures.
