摘　　要：化学实验室废水成分复杂、有机物含量多,如不处理对环境将造成重大污染。首先以模拟废水作为研究基础,用Fenton试剂法模拟对废水进行氧化处理,得到模拟废水的处理工艺条件,再结合有机蒙脱土吸附法,得出两种方法处理模拟废水的最佳工艺。最后以实验室真实有机废水为研究对象,当FeSO4·7H2O用量为3.0g,H2O2用量为5.0mL,pH值在4.0,反应时间为30min,有机累托石用量为0.5g/mL时,实验室有机废水的COD去除率可以达到87.6%。Chemical laboratory wastewater has complex composition and high organic content,which will cause serious pollution to the environment if not been treated.Based on the study of simulated wastewater,Fenton reagent method was used to simulate the oxidation treatment of the wastewater to obtain the treatment conditions of the simulated wastewater,and then combined with the adsorption method of organic montmorillonite,the optimal process of the two methods for treating the simulated wastewater was obtained.Finally,the real organic wastewater in the laboratory was taken as the research object.When the dosage of FeSO4·7H2O was 3.0 g,the dosage of H2O2 was 5.0 mL,the pH was 4.0,the reaction time was 30min,and the dosage of organic montmorillonite was 0.5g/mL,the COD removal rate of the organic wastewater in the laboratory could reach 87.6%.
