摘要：针对A/O法（厌氧/好氧交替生物处理法）处理造纸废水，对金东纸业的废水处理系统进行了研究。结果表明在设计厌氧池水力停留时间为55min和好氧池水力停留时间为13.0h的情况下，COD、TSS和BOD的去除效果好，达到排放标准；厌氧/好氧交替生物处理系统抗冲击负荷能力强，运行稳定。

AbstractFor the results of treating waste water by A/O —the anaerobic and oxic alternating biologic treatment system，the research was done on the GOLD EAST PAPER(JIANG SU) CO. LTD treatment system. Results have shows as the anaerobic HRT is 55min and the oxic HRT is 13.0h，the impact of reducing COD，TSS and BOD is good，and the discharging water achieves the national standard. Results also shows the system has powerful resistance to impact load and runs well.
