摘　　要：随着我国现代化工业的快速发展,水体受重金属及有机物的污染日益严重,特别是当工业废水处理不当任意排放会直接影响水体的自净,从而导致水质恶化。化学需氧量(COD)是检测水体受污染程度的一项重要指标,COD值越高表示水质受污染程度越严重。以常用的芬顿试剂硝酸亚铁及过氧化氢为原料,对影响反应的主要因素:芬顿试剂的最佳配比、pH、反应时间、搅拌速度进行系统探索,得到了最佳的反应条件,提高了芬顿试剂处理工业废水的能力。With the rapid development of modern industry in China,the water body is increasingly polluted by heavy metals and organics,especially when the industrial wastewater is improperly treated and discharged arbitrarily,which will directly affect the self purification of the water body,leading to deterioration of the water quality.Chemical oxygen demand(COD)is an important indicator to detect the degree of water pollution.The higher the COD value,the more serious the water pollution.Using common Fenton reagent ferrous nitrate and hydrogen peroxide as raw materials,the main factors affecting the reaction,such as the optimal ratio,pH,reaction time and stirring speed of Fenton reagent,were systematically explored,and the optimal reaction conditions were obtained,which improved the ability of Fenton reagent to treat industrial wastewater.
