| 摘 要： | 研究了折流厌氧反应器(ABR)运行中碱度的变化情况及其与ABR各格室中VFA、pH和COD变化之间的关系.结果表明,碱度沿程变化与反应器的VFA浓度变化密切相关,碱度和pH值的最低点出现在VFA浓度最高点.碱度条件是通过pH值影响系统的运行.ABR沿程碱度和pH值变化都存在一个先降低后上升的过程.碱度控制一般以保证ABR沿程最低pH值不低于6.0为准,6.5以上为佳.进水碱度的下限与反应器的进水浓度密切相关.在低负荷COD条件下3.7 kg/(m3·d)],保持ABR运行良好的最低碱度为800 mg/L.

| Abstract: | Variation of alkalinity and its relationship with the pH,volatile fatty acid(VFA) and COD along with the different compartments of the ABR were investigated.The experimental results showed that there was a close relationship between variation of alkalinity and VFA concentration along with the ABR compartments.The lowest point of alkalinity and pH value occurred where VFA concentration reached maximum.The effect of alkalinity on the operational performance was through changing pH value.The variation trend of alkalinity and pH along with different compartments was decreased firstly and then increased.The alkalinity should be controlled to guarantee the lowest pH no less than 6.0.The lowest alkalinity should be no less than 800(mg/L) when the loading rate(COD) was about 3.7(kg/(m3·d).) |
