摘　　要：采用双氧水(H2O2)氧化法处理低浓度含氰废水,研究结果表明,在进水初始pH值为7、电机搅拌速度为100r/min、体积分数为30%的H2O2投加量为2.5mL/L、反应时间为2h条件下,总氰去除率可达93%以上。实际工程应用中,出水口总氰浓度远低于国家有关排放标准。Cyanide-containing wastewater in low concentration was treated by hydrogen peroxide oxidation.The results indicated that more than 93% removal rate of total cyanide was achieved under the following reaction conditions that initial pH value is 7,motor stirring speed is 100 r/min,30% H2O2 dosage is 2.5 mL/L and reaction time is 2 h.In practical engineering applications,the value of total cyanide in the outlet was much lower than the national emission standard.
