摘　　要： 改造工程增加了气浮池和UASB反应器,对A/O反应池进行扩容,并增设填料,重新设计了水力停留时间。实际运行结果表明,系统运行稳定,处理出水COD≤87 mg/L,ρ(SS)≤66 mg/L,ρ(NH3-N)≤5 mg/L,色度≤40倍,pH=6～9。处理出水达到GB 8978-1996一级标准。 The Engineering renovation for wastewater treatment of canned fruits was introduced. The reconstruction project had increased flotation tank and UASB, the A/O system was increased the volume of tanks, and installed of packing materials, and redesigned the hydraulic retention time. The running results showed that the process had stable treatment efficiency. The COD, SS, NH3-N in the treated effluent were less than or equal to 87 mg/L, 66 mg/L, 5 nag/L, respectively. The chromaticity color was less than 40 （times）and pH=6-9. The effluent quality met the first grade criteria of integrated wastewater discharge standard （GB 8978- 1996）.
