摘要
在众多水处理技术中,絮凝法既是最古老的水质净化处理方法,又是当今众多水处理工艺技术中应用最广泛、最普遍的单元操作工艺技术,研制新型高效絮凝剂是絮凝法的核心问题之一。
     本文在聚硅酸中同时引入铁、锌两种金属离子,控制好工艺条件,研制新型水处理药剂——聚硅酸硫酸铁锌(PFZSS)。PFZSS的制备方法是:配制一定浓度的硅酸钠溶液(按SiO_2计),在酸性条件下聚合一段时间后加入硫酸铁和硫酸锌,静置陈化一段时间,使反应达到有效的聚合度。在PFZSS的制备过程中,考察溶液的pH值、硅酸钠浓度、Fe~(3+)、Zn~(2+)浓度、加药方式、投药量对PFZSS絮凝性能的影响,得到PFZSS的最佳配方和制备工艺条件。
     通过比较PFZSS与聚硅酸硫酸铁铝(PFASS)、聚硅酸硫酸铁(PFSS)、聚硅酸硫酸铝(PASS)、聚硅酸硫酸锌(PZSS)等药剂的絮凝效果、脱色效果、除油效果和聚硅酸硫酸铁锌处理餐饮废水应用实验,研究了按此配方制备的PFZSS的性能。
     实验结果表明PFZSS不仅具有吸附架桥和静电中和作用,还能同时发挥铁、锌絮凝剂的优点,且主要生产原料铁盐和锌盐来源广泛、价格较低,生产流程相对比较简单,有开发利用的前景。
Among so many wastewater treatments, flocculation is not only one of the most antiquated methods, but also the most popular operative technology, which is used widely today. However, nowadays the key problem of flocculation is to develop new and high efficacious flocculants for wastewater treatment.
    This passage introduced how to develop the new flocculants (PFZSS) for wastewater treatment through adding iron(III) ion zinc(II) ion in the silicic acid and controlling the reactive condition.
    The process of developing PFZSS is as follow. At first, prepare the sodium silicate solution in a definite concentration, then add the zinc (II) sulfate and iron (III) sulfate after the solution polymerizing in acid condition for a certain time, and then the polymerization can reach an available polymeric degree in this reaction after a period of aging time. In this work, several variables that affect PFZSS flocculation capability have been studied. Particularly, the effect of pH of the solution the sodium silicate concentration iron(III) ion and zinc(II) ion concentration the mode of adding chemical and the adding chemical amount have been considered.
    According to the results, the optimum directions and technical condition for producing PFZSS was achieved, and the flocculation capability of PFZSS produced in the light of this direction was researched.
    PFZSS' capability was evaluated in the treatment of catering trade wastewater through the comparison between PFZSS and PFASS PFSS, PASS PZSS according to the flocculation result comparison experiment the decolorized result comparison experiment and the deoiling result comparison experiment.
    These experiments indicate that PFZSS has some advantages for wastewater treatment. On one hand, PFZSS not only has the characters of general flocculants such as electric charge neutralization and linkage of the micro particles through bridges formed by the linear chain molecules, but also can exert the advantages of iron and zinc. On the other hand, the main producers' goods such as iron material and zinc material are so common and cheap to obtain, while the process of PFZSS production is so simple relatively, that the future of developing this flocculants is promising.
