摘要
本文是对经过二级处理过的造纸废水进行进一步深度处理,使其水质达到可以回用于生产的标准,实现部分废水的封闭循环。包括了水质分析试验、混凝沉淀试验和砂滤3个试验,使用了硫酸铝、聚合氯化铝、阳离子聚丙烯酰胺等混凝剂对废水进行处理,得出最佳投药条件和最佳投加剂量。
A lot of experimental studies about the secondary treatment effluent have been carried about in this paper. Part of the effluent treated can be used in the sealed effluent recycle. The experiments include three parts： the analysis of the effluent,coagulation and sedimentation, and the sand filtration, and find the best conditions of using Al2（SO4）3, PAC and PAM.
