造纸废水处理工艺的改进

Papermaking Wastewater Treatment by Improvement Process

造纸废水排放标准的日益严格,使造纸废水的深度处理变得十分必要。本工艺在原工艺基础上进行改进,采用预酸化+IC反应池+A/O+Fenton氧化塔进行处理。运行结果标明,新工艺处理效果良好,各项指标能达到国家新的排放标准(GB3544-2008)。

With increasingly strict dischange of paper wasterwater, it, s necessary to execute advanced treatment to effluents. The process on the basis of the original process improvement, hydrolysis acidification - IC - A/O - Fertton reagent process was used for the trement of paper wasterwater. The operation results showed that the effluent quality met the requirement for wheat straw in the Discharge Standard of Water Pollutants for Paper Indust（ GB3544 -2008）.
