摘要
造纸生产过程排放的污水含大量的悬浮物、纤维和ＣＯＤ、ＢＯＤ等有机污染物。ＥＷＰ高效污水净化器是利用进入的经与ＪＦ高分子絮凝剂混合的造纸污水自身生成的絮凝沉淀物，在净化器内形成稳定的、可连续自动更新的吸附过滤流动床，对污水进行一级物化处理。由于絮凝沉淀物形成的流动床有活性碳的作用，所以比气浮或沉淀的物化处理工艺提高１０％～２０％的去除率。单台设备处理能力达２５００ｍ３／ｄ。经过三年多的运行，结果表明可达到ＣＯＤ去除率为９２．５％；ＢＯＤ去除率为７８．５％；ＳＳ去除率为９８．９％。
The wastewater drained from paper making process contains a large amount of suspended substance,fiber and organic pollutants such as COD and BOD. EWP_high efficiency wastewater purifier performs primary physicochemical treatment through a stable and continuously and automatically renewable adsorption_filtration fluidized bed that is formed in the purifier by sediments of the papermaking effluent mixed with JF_polymer floculating agent.The removal rate can be 10%20% higher than that of normal air flotation or setting physicochemical treatment process.The treatment capacity of one single purifier amounts to 2500 m3/d. The results of more than three years' operation show that the removal rate of COD can reach 92.5%,BOD 78.5%,and SS 98.9%. The treated water can be recycled for reuse in the production process.
