英国经两年多的研究,认为在造纸磨机废水处理的初期阶段,即在除去溶解了的有机质方面采用诸如铝矾土,硫酸铁和膨润土等无机材料是最为有效的。他们对英国十个磨机的废水做了简单的实验室实验,采用多种材料,结果差距较大,清除效率在0—50％之间,并据此得出上述结论。当然,方法在经济上的有效性也取决于有机质存在的特点和稳定性。 After more than two years of research in the UK, it is believed that it is most effective to use inorganic materials such as bauxite, ferric sulfate and bentonite in the early stages of paper mill wastewater treatment, ie, to remove dissolved organic matter. They did a simple laboratory experiment on wastewater from ten mill mills in the United Kingdom, using a variety of materials, resulting in large differences in removal efficiencies between 0 and 50%, based on which the above conclusions were drawn. Of course, the economic effectiveness of the method also depends on the characteristics and the stability of the organic matter.
