| 摘 要： | 采用好氧活性污泥法对高碱性废水进行处理,研究了随着曝气时间的延长,废水pH值、碱度及COD的变化规律.实验结果表明,pH值随着曝气时间的延长逐步降低,而碳酸根碱度呈递增趋势,总碱度仅略有上升.经过8 h曝气后,原水pH值可由12.5降至10以下,COD去除率最高可达60.6%.

| Abstract: | Activated sludge oxidation is utilized to treat waste water with high alkalinity. The changing rules OfpH value, alkalinity and COD are studied with the change of aeration time. The result shows that pH value gradually decreases, CO3^2- alkalinity increases and the total alkalinity increases only a little with the lengthening of aeration time. After 8 hours of aerating, pH value of the original wastewater can reduce from 12.5 to below 10 and the removal rate of COD can achieve 60.6%. |
