在生物处理过程中会产生含磷和硝酸的废水。本研究开发了一种处理此类废水的材料。以废玻璃为原料制备泡沫玻璃，用硫酸铁加热制备磷吸附剂和硝酸还原载体。通过间歇和连续实验对吸附性能进行了评价。3 ~ 12 mm玻璃制品对磷酸盐的饱和吸附量为6.23 mg/g；尽管玻璃尺寸较大，但吸附量相对较高。硝酸还原反硝化作用在25%左右。
Wastewaters containing phosphorus and nitric acid are produced during biological treatment processes. In this study, a material for treating such wastewaters was developed. Foamed glass was produced from waste glass and then heated with iron sulfate to prepare an adsorbent for phosphorus and carrier for reducing nitric acid. The adsorbent performance was evaluated in batch and continuous experiments. The saturated adsorption amount of phosphate was 6.23 mg/g for the product obtained from glass of size 3 to 12 mm; the amount adsorbed was relatively high, in spite of the large glass size. The denitrification by reduction of nitrate was around 25%.
