摘　　要：采用臭氧微泡法连续处理电镀含氰废水,考察了废水体积流量、臭氧质量流量、UV灯功率密度和反应管道长度等参数影响,用分光光度计对氰离子(CN−)含量进行测定,得出了最佳的工艺条件:当废水体积流量为120 mL·min^(−1)、臭氧的进料质量流量为11 g·min^(−1)、UV紫外线灯的功率密度为35 W·cm^(−1)、反应管道长度20 m时,废水中氰离子含量降为0.098 mg·L^(−1),臭氧利用率为98.2%,达到国家规定排放标准。In this paper,ozone microbubble method was used to treat cyanide-containing electroplating wastewater continuously.The parameters of wastewater volume flow rate,ozone mass flow rate,UV lamp power density and reaction pipeline length were investigated.The content of cyanide-ion(CN−)was determined by spectrophotometer,and the best process conditions were obtained.When the volume flow rate of wastewater is 120 mL·ming^(−1),the incoming mass flow rate of ozone is 11 g·ming^(−1),the power density of UV lamp is 35 W·cmg^(−1),and the length of reaction pipe is 20 m,the content of cyanide ion in wastewater is reduced to about 0.098 mg·Lg^(−1),ozone utilization rate is about 98.2%,which meets the national discharge standard.
