摘　　要：以废纸为原料,对生产过程中各用水单元对水质的要求进行分析,通过几种不同废水处理技术对处理后水质变化的影响,采取多种水处理技术相结合,利用适当的分阶段回用水技术手段,设计出废纸制浆造纸封闭循环用水技术路线,在满足企业正常生产对水质需求的前提下,实现废水"零排放"目标。The main factor affecting papermaking wastewater reuse is its high concentration of total suspended solids which causes plug up of the water jet equipment and felt,affecting the production.Because of the high cost of wastewater deep filtration,and increase of production costs,most companies are reluctant to construct wastewater deep filtration facilities,it causes low water reuse rate.Combining using wastewater deep filtration and optimization of reuse pipe network layout,the waster water quality can meet the requirement of the production units,and also can lower the cost of the water deep filtration,it is the effective way to reduce the wastewater discharge in the recycled fiber mills.

关 键 词：造纸废水 深度过滤 优化回用水管网布局 封闭循环用水
