二次混凝工艺处理含铜废水的研究

Study on Treatment of Copper-bearing Wastewater by Twice Flocculation Process

以壳聚糖为絮凝剂 ,考察了其在不同投加量、pH值及速度梯度下处理含铜废水的效果 ;在此基础上采取二次混凝法处理高浓度模拟含铜废水。与其它处理工艺相比 ,二次混凝法在处理效果及处理费用方面均显示出了优越性 ,为实际含铜废水的处理提供了很好的参考价值。

Using chitosan as the flocculants,effects of the different doses,pH degree and the speed of blending on treating wastewater were discussed. the high density imitateing waste water which contains the copper was treated by twice floeculation process. Comparing to other processes,The method at the treating results and expenses all displayed more superior,and for the treatment of actual containing copper waste water provided the good consult value.
