| 摘 要： | 研究了铝絮凝剂对活性污泥中微生物活性影响 ,结果表明 ,在投加量较高时 ,游离态的Al3+对活性污泥的影响高于聚合态的铝。随着絮凝剂与活性污泥接触时间的增长 ,抑制作用增大。但随着活性污泥浓度的提高 ,微生物的耐受力有所增强 ,即活性污泥对铝絮凝剂有一定的适应性。二次暴露实验的结果还表明 ,铝絮凝剂对活性污泥的影响是非急性的。

| Abstract: | The effect of aluminum flocculant on activity of microbe in activated sludge is studied in this paper.The results show that the free Al 3 has higher effect on activated sludge than polyaluminum has in high quantity of flocculant.The bacteriostatic action is enlargd when the conact time of the flocculant with activated sludge is increased,but the activated sludge concentration is increased, and survivability of microbe is reinforced,in another words,microbe in activated sludge has a certain suitability for the aluminum flocculant.The re exposure experiment also shows that the effect of the aluminum flocculant on the activated sludge in non acute. |
