摘要： 针对锦州某玉米深加工企业采用UASB/生物接触氧化方法处理玉米淀粉生产废水，研究主要对UASB反应器启动、运行以及颗粒污泥的结构特性进行实践与探讨。结果表明：UASB反应器经过启动阶段、负荷提高阶段以及稳定运行阶段后，可实现进水量为4513 m3•d-1，进水CODCr平均浓度为7867 mg•L-1，反应器CODCr负荷为7.3 kg•m-3•d-1，出水CODCr浓度为480 mg•L-1，去除率为94%，运行稳定。

Abstract: UASB reactor’s start-up, operation and structural characteristics of granular sludge were mainly studied based on the treatment of cornstarch wastewater by USAB and bio-contact oxidation process on maize deep processing in an enterprise of Jinzhou, Liaoning province. The results show that after the USAB reactor goes through three stages, i.e. start-up stage, load increasing stage and stable operation stage, the average water inflow is 4513 m3•d-1, the average CODCr concentration of the inflow is 7867 mg•L-1, CODCr load of reactor is 7.3 kg•m-3•d-1, CODCr concentration of effluent is 480 mg•L-1, the average removal rate reaches about 94%, and the reactor operates continuously and stably.
