摘　　要：针对维生素B1生产废水成分复杂、难于生化降解、水质不稳定、固体悬浮颗粒含量高的特点,采用混凝—微电解法进行预处理。当混凝剂三氯化铁的投加质量浓度为150mg/L,微电解反应器内pH为4.2,反应时间为50min时,出水TOC和COD的去除率分别达到77.4%和82.3%,对SS的去除率也达95%,同时有效提高了废水的可生化性。Coagulation- micro-electrolysis process has been used for pretreating the wastewater from vitamin B1 production,which is characterized by complicated composition,refractory,unstable quality and high suspended solids. When the coagulant,ferric chloride,dosage is 150 mg/L,the pH in the micro-electrolytic reactor is 4.2,and reacting time is 50 min,the removal rates of TOC and COD are 77.4% and 82.3% respectively,the SS removal rate gets to 95%,and at the same time the biodegradability of wastewater is improved distinctly.
