摘　　要：淀粉糖废水是一类高浓度有机废水,现阶段的处理工艺主要是厌氧-好氧生物处理组合工艺。本研究主要针对好氧段进行改进,以改良型移动床生物反应器(MBBR)工艺对淀粉废水进行高效处理,通过对MBBR工艺中的填料结构进行设计优化及表面修饰,同时对工艺曝气条件进一步优化。结果表明:改进后的MBBR工艺可在高有机负荷率(OLR)的条件下稳定运行处理淀粉糖废水。改进后的MBBR工艺水力停留时间(HRT)为6 h,以化学需氧量(COD)计,容积负荷可达到10~12 kg/(m^(3)·d)。经MBBR工艺处理后,出水水质达到《污水排入城镇下水道水质标准》(GB/T 31962-2015)排放标准。Cassava alcohol wastewater has high organic matter and is mainly used in anaerobic and aerobic digestion. This study focused on the process of the aerobic digestion to treat starch wastewater by a modified moving bed biofilm reactor(MBBR) process. The results show that the MBBR process could treat starch sugar wastewater with high organic loading rate(OLR) because of modified carrier filler and improved aeration system. The modified carrier had its advantages of optimized structure and surface. Optimized MBBR process needed 6 h of hydraulic retention time(HRT). The organic loading rate reached 10-12 kg/(m^(3)·d), according to COD. The effluent quality meets the discharge standard of GB/T 31962-2015 when the wastewater was treated by the MBBR process.
