摘要
对酵母菌处理系统运行中出现的膨胀问题的诱因以及控制对策进行了较为系统的研究 .研究结果表明 :该系统的膨胀问题最终是由丝状真菌引起 ,其中白地霉是膨胀的主要导致因素 ;皮状丝孢酵母菌种的存在是另一个可能的诱因 ;废水中氮元素含量极端贫乏是加速膨胀的另一个重要原因 .作为应急控制的对策 。
The inducements and controls to filamentous bulking are systemally studied. The results were show: the question of sludge bulking in treatment system is ascribed to the filamentous fungi; Geotrichum candidum link is a main factor and Trichosporon Cutaneum is possible another inducement; meanwhile, the deficiency of nitrogen element in wastewater is another important factor that accelerating the filamentous bulking. As the methods and controls to meet an emergency, sodium propionate and sodium hypoch...
