摘　　要：以老龄垃圾渗滤液生化段后混凝出水为对象,考察了臭氧投加量、反应时间、铜基臭氧催化剂用量对CODCr去除总量和去除率的影响,并通过重复使用试验考察了催化剂的稳定性。结果表明,最佳反应条件为:臭氧投加量为90 mg/L,反应时间为90 min,催化剂投加量为10.0 g/L;该条件下,CODCr平均去除量为98.3 mg/L,CODCr的平均去除率为43.40%,相对于单独臭氧CODCr的平均去除率提高了104.23%,臭氧的投加量与CODCr总去除量比值为0.92,重复使用过程中铜基臭氧催化剂的催化能力具有很好的稳定性。The effects of ozone dosage, reaction time and dosage of copper-based ozone catalyst on CODCr removal amount and CODCr removal rate were investigated, and the stability of the catalyst was investigated through repeated use experiment. The results showed that the optimal reaction conditions were as follows: ozone dosage of 90 mg/L, reaction time of 90 min, catalyst dosage of 10.0 g/L. Under this condition, the average CODCr removal amount and the average CODCr removal rate were 98.3 mg/L and 43.40 %, respectively. Compared with ozone alone, the average removal rate CODCr increased by 104.23 %. The ratio of ozone addition to the total CODCr removal amount was 0.92 and the catalytic capacity of the copper-based ozone catalyst had good stability in the process of reuse.
