【摘要】 本文进行了用硫铁矿烧渣制备聚合硫酸铁(PFS)的实验研究。并在此基础上对聚合硫酸铁作了改性探索。研究表明,所得产品的总铁含量和盐基度均符合行业标准和国家标准,且对造纸工业废水的处理效果很好,其CODcr的脱除率达90%以上。该方法工艺简单,反应时间短,对环境友好,为废渣综合利用指出了一条有效途径。更多还原

【Abstract】 Polymeric ferric sulfate(PFS) was prepared by pyrite cinder in this paper.Furthermore,modificated PFS was studied.The result shows that the total icon and basicity of PFS are agreements with the industrial standard and national standard.This process has many advantages such as simple technology,short reaction time and good for environment.It designates an efficient way for the comprehensive utilization of the cinder.更多还原
