【摘要】 对纸机白水回收循环利用的可行性进行了研究,结果表明,纸机白水经过简易的自然絮凝和多段物理沉淀,即可回用于网部导辊喷淋,水耗降低51%。将烘缸冷却水用于网部喷淋,可以使水耗下降9%。这两项技术改造,使整体水耗由32.7m3/t纸,下降至13m3/t纸,下降60%,外排白水量下降44.3%。更多还原

【Abstract】 the feasibility to recycle the white water was studied in the paper.It has been confirmed that white water,which is treated simply by natural flocculation or physical precipitation for multi sections,could be reused in the spray of guider roller in the wet end.As a result,the water loss could reduce 51%.The cooling water from paper dryers could be also recycled to spraying the guider roller,which could reduce the water loss by 9%.Because of the two technical reforms,the whole water loss could be reduced by 60% from 32.7m 3/t to 13m 3/t.As a result,the white water discharged could be reduced by 44.3%.更多还原
