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。
Colonic fermentation, bacterial growth, fecal bulking, transit time and the energy value of foods are all affected by the presence of resistant starch. 结肠发酵、细菌生长、粪便体积、排空时间和饲粮能量值等都受到抗性淀粉的影响。
The factors affecting the sludge bulking were discussed from the aspects of wastewater quality, such as wastewater with high content of carbon hydrate, decayed wastewater, wastewater with toxic substance, wastewater with unbalanced content of N and P and wastewater with low pH value; 从碳水化合物含量高的废水、陈腐或腐化的废水、含有毒物质的废水、N、P含量不平衡的废水、低PH值的废水等方面论述进水水质对污泥膨胀的影响;
Activated sludge bulking due to low pH value& organic loading and its resume 低pH值与低有机负荷引起的活性污泥膨胀及其恢复
