针对我国高校实验室高浓度化学废液污染的难题，设计了铁炭微电解一超声波-Fenton法-絮凝沉淀组合处理技术。铁炭微电解的优化工艺条件为：pH=4，V（Fe）：V（c）-2：1，固液比为1：4，反应时间60min，循环反应2次；Fenton氧化工艺条件为：pH=4，投加Fenton试剂，反应时间60min；絮凝沉淀反应条件为：pH值为7，投加PAM5mg／L，PAC300mg／L。试验结果表明，废液COD。，总去除率达90％，且生化性明显提高，为高校实验室高浓度化学废液无害化处理探索可行的途径。

In order to properly deal with chemical waste from university laboratory, experiments are designed using combined iron carbon micro electrolysis-uhrasound-Fenton-flocculation precipitation technology , to explore the suit- able condition for chemical waste removal. Results suggest optimized condition for iron carbon micro electrolysis process regester： pH=4,V（ Fe ）： V（ C ） = 2：1, solid-liquid ratio is 1：4, reaction time regesters 60 min, cycled the reaction twice; the condition for fenton oxidation process is： pH=4, Fenton reagent addiction, 60min for reac- tion time; while conditions for the coagulation sedimentation reaction appear to be ： pH=7, the dosage of PAM is 5 mg/L and PAC is 300 mg/L . Experimental results suggest total removal rate of CODcr registers 90% with im- proved biochemicality of the waste liquid. Finally, the paper concludes the proposed technique proves to be a feasible way for laboratory waste disposal.
