| 摘 要： | 活性污泥中丝状菌与絮状菌的竞争生长污泥的性状发生变化，有机负荷对污泥膨胀的影响的一直有两种完成相反应的说法。我们对此作了专门研究，试验结果表明：当反应器中溶解氧充足时，低有机负荷易引起污泥膨胀，提高有机负荷能有效的控制膨胀，高负荷下，引起污泥膨胀的原因往往是ＤＯ浓度不足，而提高ＤＯ浓度则能使污泥膨胀得到控制。这一结果也解释了高有机负荷发生泥膨胀的实质原因。

| Abstract: | In the activated sludge process,the character of activated sludge will be changed by competitive growth of floc\|forming bacteria and filamentous bacteria.There are two different arguments about the effect of organic loading on sludge bulking all long,therefore we have had specific research on it.The experimental result shows that if low organic loading condition can be maintained,bulking will occur,however the bulking will be controlled effectively in the condition of increasing organic loading.Under high organic loading condition,usually,the owing to the insufficient DO,bulking may occur, but,if DO concentration is increased,bulking will be controlled.In addition,the result explains the reason why sludge bulking occurs at high organic loading.. |
