Abstract

Organic coagulants have gained increasing popularity over the past 30 years because they are considered cheaper and more user-friendly than traditional mineral hydrolysing coagulants. Regrettably, in-depth studies have not yet been conducted on their ability to purify water to a healthy palatable drinking quality which is risk-free for lifetime consumption in terms of the national standard for drinking water quality of various countries worldwide, and does not become a source of secondary pollution in the reticulation system. The objective of this paper is to provide information about the natural organic matter (NOM) removal efficiency attained at different waterworks purifying water with different organic coagulants, and to compare this with that attained using mineral coagulants. The findings presented in this article prove that organic coagulants are not an equivalent replacement for mineral coagulants, as the purified water is of an inferior quality which does not comply with the limits set by national standards of different countries worldwide.
有机混凝剂不能将饮用水净化到可达到的最佳质量
在过去的30年里,有机混凝剂越来越受欢迎,因为它们被认为比传统的矿物水解混凝剂更便宜,更容易使用。遗憾的是,它们是否能够将水净化到健康可口的饮用质量,达到世界各国饮用水质量国家标准的终身饮用无风险,并且不会成为管网系统的二次污染源,目前还没有深入的研究。本文的目的是提供不同水厂使用不同有机混凝剂净化水所获得的天然有机物(NOM)去除效率的信息,并将其与使用矿物混凝剂所获得的效果进行比较。本文的研究结果证明,有机混凝剂不能等效替代矿物混凝剂,因为纯净水质量较差,不符合世界各国国家标准规定的限值。
