摘要:天津某造纸厂采用内循环(IC)反应器-表面曝气氧化沟-Fenton氧化法工艺处理废纸造纸废水,处理规模为25000 m3/d。运行结果表明,此工艺能有效处理废纸造纸废水,出水pH值≤7.2、CODCr≤52 mg/L、BOD5≤10 mg/L、SS≤8 mg/L,出水水质达到GB 3544—2008制浆造纸工业水污染物排放标准的要求。
Abstract:The wastewater from a recycled paper mill in Tianjin City was treated by using IC-Surface aeration oxidation ditch-Fenton process. The treatment capacity was 25000 m3/d. The operation results showed that recycled paper mill wastewater could be treated effectively through this process. The values of pH, CODCr, BOD5 and SS of the effluent were equal to or less than 7.2, 52 mg/L, 10 mg/L and 8 mg/L respectively. The effluent quality met the discharge regulation for pulp and paper industry (GB 3544—2008).
