A/O两种工况条件下污泥电位的分析研究

Comparative Study on Sludge Potential by A/O Process

通过模拟水解酸化—好氧工艺,并以模拟印染废水为处理对象,比较分析了在80%和50%回流比下,水解酸化池与好氧池中污泥电位的变化,探讨了最适回流比。结果表明,回流比为80%的回流工艺的污泥电位以及污泥性质优于回流比为50%回流的工艺。

Stimulated printing and dyeing wastewater has been treated by hydrolysis acidification-aerobic process. The changes of sludge potential in hydrolysis acidification pool and aerobic pool when reflux ratios are 50 % and 80 %, respectively, are compared. The optimal reflux ratio is discussed. The results show that when reflux ratio is 80 %, the sludge potential is superior to that when reflux ratio is 50 %.
