摘　　要：研究了改性膨润土对J酸溶液和J酸废母液的处理效果，结果表明，改性膨润上对J酸溶液的处理效果比J酸废母液要好，对J酸废母液的去除效果与pH和硫酸钠含量有关，在中性或弱碱性条件下，硫酸钠含量越低，对J酸废母液的去除率越高，最高可达到50％左右。Modified bentonite was used to treat J acid and J acid industrial wastewater. The results showedthat the COD removal efficiency of J acid industrial wastewater by modified bentonite was better than that of Jacid, and its removal efficiency could reach 50 % in the condition of low Na2SO4 and pH = 7. 0-8.0
