摘　　要：厌氧驯化后的活性污泥经过PVA硼酸法包埋制备成的固定化小球经硬化处理后添加在厌氧-好氧反应系统的厌氧反应器中,同时在相同条件下设置对照组A,对皂素废水进行处理。试验包括两套反应器的启动、运行、抗冲击负荷等环节。结果表明,固定化组C在产气量、抗毒性和有机负荷冲击、COD去除率等方面均优于对照组A。This paper relates to a benchscale experiment for treating wastewater from processing of dioscorea for extracting diosgenin. Pellets made of poly-vinylalcohol (PVA) are used for immobilizing anaerobic sludge, and the experiment result compared with that of the conventional UASB has showed several advantages such as higher COD removal and better resistance to loading shock.
