复合式厌氧折流板反应器酸解过程及调控措施研究

Study of Acidulation Process and Control Measures in HABR

试验主要研究酸解过程及其调控对复合式折流板反应器(HABR)运行过程的影响。在反应器酸化期和酸化调控期,通过观察各隔室碱度和pH值的变化规律,对各个隔室及整个反应器的处理效果进行研究。完全酸化期,碱度出现"0"值,各隔室pH值均处于4以下,COD去除率仅达到56.21%,酸化的主要原因是HABR系统中碱度不足和一隔室负荷过载。试验采用降低有机负荷和投加碱性物质相结合的方法,经过34d使系统快速恢复正常运行。

The experiment research the affect of acidulation process and control measures on HABR.Respectively,in the acidification and control phase of reactor,by observing the changes of microbiofacies,alkalinity and pH in every compartment study the treatment effect of the reactor and each compartment.In the Fullacidification phase,when alkalinity is zero,pH of each compartment is below four,the removal rate of COD is only 56.21%,the acidification of HABR system caused by inadequate alkalinity and local overload.This test take the mesures of reducing organic loading and adding alkaline matte,after 34 days,the system return to normal quickly.
