ABR处理淀粉废水的研究

探讨了厌氧折流板反应器（ABR）的运行机理,并研究了启动阶段在不同的水力条件和容积负荷下,对有机负荷为1.2-3.6 kgCODcr/（m^3·d）淀粉溶液的CODcr去除率,以及ABR工艺运行过程中的影响因素进行分析。研究结果表明,在启动阶段中低负荷反应条件下：①HRT12 h、CODcr600 mg/L、容积负荷1.2 kgCOD-cr/（m3·d）②HRT12 h、CODcr1 200 mg/L、容积负荷2.4 kgCODcr/（m3.d）;③HRT8 h、CODcr1 200 mg/L、容积负荷3.6 kgCODcr/（m3.d）,ABR反应器对CODcr均有较高的去除率。运行稳定后,ABR反应器的CODcr去除率在80%左右。

Study on the Treatment of Starch Wastewater by Anaerobic Baffled Reactor(ABR)

This article has discussed the anaerobic baffle reactor （ABR） movement mechanism, and has studied the unloading phase under the different water power condition and the volume load, to the organic load is 1.2 -3.6 kgCODcr/（mad） starch solution CODcr elimination rate, as well as in the ABR craft movement process＇s influencing factor carries on the analysis. The findings indicated that in unloading phase under low load reaction condition：①HRT 12 h, CODe, 600 mg/L, the volume shonlder 1.2 kgCODcr/（ m^3 d） ; ②HRT 12 h, CODcr 1200 rag/L, the volume shoulder 2. 4 kgCODcr/（ m^3 d） ; ③HRT 8 h, CODe, 1200 mg/ L, the volume shoulder 3.6 kgCODcr/（ m^3d）, the ABR reactor has the high elimination rate to CODcr. After moving stably, ABR reactor＇s CODcr elimination rate about 80%.
