APMP废水处理改造工程试验研究

The Study on Reconstruction Project of APMP Wastewater Treatment

河南省某造纸厂近期因生产工艺改造和原料变化导致水质恶化,同时河南省环保局提高了制浆造纸废水的排放标准。为此,对现有处理工艺存在的问题进行了分析,提出了IC/传统活性污泥法/U形流BAF替代工艺,试验结果表明,该工艺处理后的最终出水满足排放标准。

Wastewater ofa papermaking factory in Henan province became worse, because of the change in producing techniques and material. Besides, the Pulp and Papermaking Wastewater discharge Standard was raised by Henan EPA. Based on the analysis of existing problems inherent treatment process,a modified process of IC/traditional activated-sludge method/U-BAF was put forward. The study indicates that the effluent quality meets the new standard.
