采用臭氧催化氧化技术对大庆炼化公司丙烯腈废水进行深度处理,处理能力为20 m3/h。在实际进水COD远远高于设计进水浓度条件下,臭氧催化氧化装置对COD的去除总量大大高于设计值(1 kg/h),平均为1.88 kg/h。在高负荷条件下,该装置处理效果优于预期,但同时也存在催化剂污染等问题。通过每周1次的定期气水联合反洗,可保证装置稳定运行并维持良好的处理效果。

Catalytic ozo nation technology has been used for the advanced treatment of the acrylonitrile wastewater from Daqing Branch,Oil Refinery Chemical Co.,CNPC,whose treatment capacity is 20 m3/h. Under the condition that the COD of actual influent is much higher than the designed influent concentration ,the total amount of COD removing capacity is averagely 1.88 kg/h,much higher than the initially designed value,1 kg/h. Under the high load condition,the treatment effect of this system is better than what was expected,but in the meanwhile,problems,such as catalyst pollution,etc.,have occurred. By means of periodic air-water backwashing once a week,the system can run steadily and keep good treatment effect.
