摘要
利用铁碳内电解技术对草制浆造纸中段废水进行预处理研究.通过正交试验确定铁碳内电解技术处理草制浆造纸中段废水的主要影响因素、顺序及其最优水平组合,废水的pH值为4.37,铁屑量（V）/原水量（V）为13%,反应时间为1.5 h,焦炭量（V）/铁屑量（V）为1.0.在正交实验的基础上,通过动态试验研究确定了最佳工艺运行条件,即在曝气条件下,原水pH值调节至4.0左右,水力停留时间HRT为1.5~2.0 h,铁碳内电解技术处理草制浆造纸中段废水的CODcr和色度的去除率分别达到65%与50%左右.
This paper reports the results of the treatment of straw pulp papermaking wastewater using the technology of internal electrolysis. The optimum level combination, their influence and order established through orthogonal experiment suggests that the pH of the raw water should be around 4.0, the ratio of the volume of the ferric fillings to that of the raw water be 13%, the HRT（Hydraulic Retention Time）be 1.5h, and the ratio of the volume of the ferric fillings to that of the coke be 1.0. The optimum experimental conditions are optimized and confirmed through continual experiment on the basis of the orthogonal experiment, that is when the pH of the raw water is around 4.0, the HRT is between 1.5- 2.0 hours, and under the condition of aeration, the removal efficiencies of CODcr and chromaticity can respectively reach about 65% and 50%.
