| 摘 要： | 研究投加游离氯对曝气生物滤池(BAF)实现短程硝化的可行性,考察游离氯对亚硝酸盐积累的作用规律,并探讨改变加氯量和氯的投加方式对稳定维持BAF亚硝酸盐积累的影响。研究结果表明,通过加氯可以实现曝气生物滤池亚硝酸盐的积累;当进水游离氯质量浓度为4 mg/L时,BAF系统连续运行20 d后亚硝酸盐积累率可达60%~70%;当系统形成稳定的亚硝酸盐积累时,降低进水游离氯的质量浓度能够稳定维持亚硝酸盐积累;间歇加氯在一定程度上也能够维持亚硝酸盐积累。

| Abstract: | The feasibility to achieve shortcut nitrification-denitrification by free chlorine in biological aerated filter(BAF) and the effect of which on the accumulation of nitrite were studied.Different chlorine dosage and adding modes of free chlorine were also investigated to maintain the accumulation of nitrite in BAF.The results show that the accumulation of nitrite can be achieved by adding free chlorine in this experiment;When the influent concentration of chlorine is 4mg/L,the concentration of effluent nitri... |
