【摘要】 通过试验和观察，研究了活性污泥中丝状菌与絮体结构的关系。常见的活性污泥絮体可分为六大类型，在不同的处理工艺和运行条件下，各类型污泥比例不同，丝状菌在污泥絮体的形成过程中所起的作用也不相同。而在活性污泥膨胀时，生物相结构中的丝状菌可分为结构性的和非结构性的两大类，它们起着不同的作用，运行中必须通过不同的方法和措施加以防治。更多还原

【Abstract】 The relationships between filamentous organisms and flocculate structure in the activated sludge were studied in this paper. It was found that the structure of activated sludge could be divided into six types. The proportion of each type and the action of filamentous organisms on the formation of sludge structure would be different under different treatment processes and operating condition. Sludge bulking could be divided into structure filamentous organisms bulking and non-structure filamentous organisms bulking, different measure should be taken in order to control the bulking.更多还原
