摘　　要：研究了废新闻纸碎浆过程中影响阴离子杂质溶出的因素,结果表明:为了避免阴离子杂质在碎浆过程中大量溶出,将NaOH用量控制在2%以下,将H_2O_2用量控制在1%;碎浆时间控制在20min以下。The influencing factors of dissolved and colloidal substances released during the repulping of ONP were studied. The results show that the charge of NaOH is controlled under 2%, the dosage of H2O2 under 1% and repulping time within 20 minutes, in order to avoid anionic trash largely released in the process of repulping.
