摘　　要：采用初沉-水解酸化-好氧-二沉工艺处理箱纸板生产废水,处理后回用水质CODCr在600mg/L以下,完全可以回用到生产车间,实现了生产废水的封闭循环,且运行效果稳定。This paper introduces the design and operation of a recycled liner board mill wastewater treatment. Process of＂Primary sedimentation ＋ hydrolysis ＆ acidification ＋ aerobic ＋ secondary sedimentation＂ is employed. The CODCr of raw water and outflow are 3000-4000 mg/L and less than 600 mg/L respectively, and the treated water is fully reused in production. The system closure of the mill is realized and the system is running stably.
