摘　　要：采用微电解/厌氧水解酸化/SBR组合工艺处理难生物降解的化学制药废水。结果表明:微电解/厌氧水解酸化预处理可大大提高化学制药废水的可生化性,其BOD5/COD由0.13增至0.64。在SBR处理系统中,当污泥负荷控制在0.5kgCOD/(kgMLSS.d)、曝气为10～12h时,对COD的去除率可达到85%以上,污泥增长速率约为1.5kg/(m3.d)。The combined process of micro-electrolysis,anaerobic hydrolysis acidification and SBR was used to treat pharmaceutical wastewater. The results show that the micro-electrolysis and anaerobic hydrolysis acidification pretreatment can greatly improve the biodegradability of the chemical pharmaceutical wastewater,and its BOD5/COD is increased form 0.13 to 0.64. In SBR treatment system,when the sludge loading is controlled at 0.5 kgCOD/(kgMLSS·d) and the aeration time is 10 to 12 h,the removal rate of COD is abo...
