There is a large number of pulping wastewater. It had important effect on the development of paper industrial that is chosen appropriate way to treatment of wastewater. In this paper, we treated wastewater by electron-beam. Without adding any chemic additive, we found that the chemical oxygen demand decline to 463 mg/L which had reached the third grade of emission control regulation, when the rate of radiant absorb dosage is 3.5kGy/s and radiant time is five second. Electron-beam took advantage of improving...
