摘要
介绍了聚合硅酸硫酸铁的制备及处理印染废水的方法,研究了最佳的实验条件。该方法工艺流程简单,药剂成本较低,废水的COD去除率达80%,脱色率达90%,出水水质达到了印染废水综合排放标准(GB8978-1996)一级标准。
A treatment method of dyeing wastewater by using self-made polyferric silicate sulfate was introduced and the optimum experimental conditions were researched. The process of this method is simple and the drug cost is low. The COD removal efficiency was over 80%, the efficiency of decolourization was 90%, dyeing wastewater could be treated to meet with the first grade standard of dyeing wastewater discharging.
