Comparison of two methods on ABR reactor quick start

摘要: ABR反应器的启动是ABR反应器能否高效稳定运行的关键,其影响因素很多。为了更好地实现ABR反应器的启动,提出了通过2种不同启动方法的对比,即1#反应器采用好氧预挂膜的方法,2#反应器采用低负荷启动法,得出的结论为,好氧预挂膜启动法的启动时间短,COD去除率高,出水pH稳定,颗粒状污泥生长情况较好,是一种可推广的启动方法。Abstract: The key of ABR reactor start-up is whether operation efficient and stable or not. In order to achieve better startup of the ABR reactor,a comparison between two different methods was made, 1# reactor used the aerobic reactor linked to prefilm method, 2# reactor used the lowload start. The conclusion is that aerobic prelaunch of film pegged to the start-up time is shorter, its efficiency of COD removal is high, the pH of effluent quality is stable, the growth of granular sludge is good.
