| Abstract:The combined persulfate oxidation and double-membrane advanced method were used to treat the biochemical effluent of a pulping and papermaking enterprise with a good treatment effect and strong shock load resistance， which could effectively ensure that the effluent quality of the system reached the standard steadily. Continuous monitoring data and long-term operating conditions showed that the average effluent CODCr was about 12.9 mg/L， ammonia nitrogen was about 0.91 mg/L， total nitrogen was about 3.92 mg/L， total phosphorus was about 0.10 mg/L. The water quality indicators were better than that of GB/T 19923—2005 industrial water quality requirements， which could be reused. |
