| 摘 要： | 根据漂珠密度小于水的特点,以水为介质从粉煤灰中成功提取漂珠,利用煅烧除炭、酸洗除杂及活化的漂珠对生活污水进行处理,研究了煅烧温度、酸洗盐酸的浓度、活化剂的种类及生活污水的浓度等对漂珠吸附性能的影响。结果表明,粉煤灰漂珠经过700℃高温煅烧后,按照液固比5∶1加入5%的盐酸洗涤,利用6 mol/L的H2SO4进行活化后其吸附性能最好,而且生活污水的COD含量越高,CODcr去除率越高。

| Abstract: | Compared with water ,fly ash floating beads have low density.So water is used to extract floating beads from fly ash.The floating beads is calcined and picklinged to deprive charcoal and impurity.Then dispose the sewage with activated fly ash floating beads.Investigate the influence of calcination temperature, HCl concentration, activator species and sanitary waste concentration on the adsorption performance.The results show that the optimal condition is that, the calcination temperature is 700℃ , the ratio of liquid （5 percent HCI）to solid is 5 ： 1 ,and the active agent is 6 mol/L H2SO4.The removal rate of COD rincrease with the rise of COD content in domestic sewage. |
