| 摘 要： | 采用生物慢滤技术处理含有葱的微污染水.当反应器中浊度、氨氮、COD(Mn)的去除率基本恒定时,认为慢滤反应器已进入动态平衡状态.在反应器进入平衡状态后,分别进行去除蒽的试验研究.实验结果表明,填加活性炭生物慢滤反应器能在更短运行时间内对浊度、氨氮、COD(Mn)等达到稳定的去除效果,但随着运行时间的增加,填加活性炭反应器与石英砂反应器有相近的去除效率;对含有同一浓度葱的原水(1 000 ng/L),形成成熟稳定生物膜的慢滤反应器运行3d后,对蒽有较为稳定的去除率;不同浓度葱原水(100～10 000 ng/L)经过慢滤反应器后,出水蒽含量均降低到100 ng/L以下,葱的去除率在70%以上;慢滤反应器的滤料高度对葱的去除效果有一定的影响,但反应器对蒽的去除主要发生在填料上部30 cm高度内.

| Abstract: | A study is made of the treatment of the anthracene in micro-polluted raw water by slow sand filtration.When the removal rate of the turbidity,ammonia and nitrogen is stable,the slow sand filtration is considered to be in the status of dynamic balance,in which status the experimental study of anthracene degradation is carried on.The results show that,the slow sand filtration reactors with extra activated carbon filled have stable removal efficiency to the turbidity,ammonia and nitrogen in a shorter time,but ... |
