A study on the effect of sludge loading on filamentous sludge bulking in SBR is described in this paper.
在严格控制sBR工艺试验运行条件下，就污泥负荷对丝状菌污泥膨胀的影响规律进行了研究。
In this paper, a new type of sludge bulking problem caused by high loading rate is described, the control measures for this kind of problem has been studied.
提出一类高负荷的丝状菌污泥膨胀现象，并对高负荷引起的污泥膨胀控制进行试验研究。
The result of experiment shows that sludge bulking will take place at any level of organic loading as long as the value of dissolved oxygen(DO) changes correspondingly.
实验结果表明，在低、中、高负荷时，只要溶解氧发生变化，均有可能发生膨胀。
The experimental result has been revealed that the dissolved oxygen limiting is the main reason for high loading rate bulking problem.
试验结果表明高负荷引起的污泥膨胀是由于溶解氧限制所造成。
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.
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污泥膨胀的实质原因。
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.
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污泥膨胀的实质原因。
