Abstract:

Paper-making wastewater is processed through coagulation,oxidation,sand filtering and activated carbon absorption in static and dy namicex periments.The COD_Cr values of the samples that have been processed are low and the water can be drained or in other usage.Cost accounting of this experiment has been carried out,and compared with other methods of wastewater treatment.This method is economical and reasonable.

Key words: paper-making wastewater, chemical coagulation, oxidation

摘要：

利用自行研制的混凝剂DH1,在静态、动态实验中,对造纸废水进行了絮凝、氧化、砂滤、碳滤处理。处理后的水样COD去除率高且稳定,水质达到国家二级水质标准。对该实验过程进行了成本核算,和国内其它造纸废水处理方法相比,该方法经济合理。
