以碱度作为青霉素废水水解酸化控制参数实验

Use ot Alkalinity as Control Parameter for Hydrolytic Degradation on Treatment of Penicillin Wastewater

研究了改进序批式生物膜法中水解阶段不同碱度类型和浓度下,碱度、pH值以及CODcr去除率的变化 规律．在一定范围内,对于同一种调节物质来说,碱度越高,水解效果越好．利用NaOH和NaHCO3调节碱度时 发现存在快速水解阶段,对于青霉素废水来说该阶段时间为1 h,这种现象可以用非平衡增长理论来解释．试验 结果还表明在一定范围内,可以应用碱度和pH值来调控水解时间．

The effect of different types of alkalinity and different concentrations of the alkalinity on alkalinity, pH, and the removal rates of CODcr in hydrolytic degradation was systematically investigated in a Modified SBBR reactor. In some extension, for the same substrate, the higher alkalinity is, the better result of the hydrolytic degradation will be attained. When using NaOH and NaHCO3 to adjust alkalinity, a fast hydrolytic degradation phase can be found. As far as Penicillin wastewater is concerned, this ...
