随着废纸利用率的提高以及为保持和提高产品的质量,纸中纤维以外的无机物和有机物成分增加,导致系统内循环白水和排水的浓度上升、污浊程度增加。在生产中,没有积极采取措施减少单位清水消耗量和单位排水量并对白水和排水进行有效处理,因系统水平衡 With the improvement of utilization rate of waste paper and the increase of the quality of products, the content of inorganic substances and organic substances other than fibers in the paper increases, resulting in the increase of circulating white water and drainage concentration in the system and the increase of the degree of pollution. In production, no active measures have been taken to reduce unit consumption of water and discharge per unit of water and to effectively treat white water and drainage.
