| 摘 要： | 利用水泥的表面吸附和水化反应性质处理垃圾渗滤液生物处理尾水可以取得很好的效果,尾水的CODCr去除率可达到69.5%.处理效果与水灰比、反应时间密切相关,低水灰比和较长反应时间对尾水的CODCr去除更为有利.通过添加一定比例的CaCO3和CaO2可显著改善高水灰比时的尾水处理效果.

| Abstract: | The tail water produced by biological processes is well treated by cement based on its capability of surface adsorption and hydration reaction. The removal rate of CODCr can hit 69.5%. The treatment effect is related to water cement ratio and reaction time. Low water cement ratio and long reaction time are propitious to the removal of CODCr. The treatment effect of high water cement ratio can be improved remarkably by adding some CaCO3 and CaO2. |
