摘要
聚合硫酸铁是一种新型无机高分子絮凝剂,广泛用于各种工业污水的混凝净化处理。本文综述了聚合硫酸铁的制备方法并比较了各自的优缺点,同时还介绍了聚合硫酸铁在改性方面的研究进展,但在改性聚合硫酸铁及其分子设计方面的研究还比较欠缺。如何加强对PSF的改性研究,以进一步提高其絮凝性能,仍是尚待攻克的课题。
Polyferric sulphate （PFS） is a kind of efficient inorganic polymer flocculants, it is widely used in waste water treatment. The preparation technologies of PFS are reviewed, and their advantages and disadvantages are also compared in this paper. In addition, the progress on the modification of PFS is also reviewed. However, the study on modified PFS and the molecular design is inadequate. Thus, how to improve the properties of PFS by modification is need to be further studied.
