Cd2+对好氧颗粒污泥同步硝化反硝化过程的影响OA北大核心CSCDCSTPCD
Effects of Cd2+ on Simultaneous Nitrification and Denitrification in Aerobic Granular Sludge SBR
研究了SBR中不同质量浓度的Cd2+对好氧颗粒污泥同步硝化反硝化过程的影响.实验结果表明:低ρ(Cd2+) (0.1 mg/L)可促进硝化反应的进行,而高ρ(Cd2+)(大于3.0mg/L)会对硝化反应产生抑制作用；Cd2+的加入导致反硝化速率降低,且对同步硝化反硝化脱氮效率产生一定抑制作用；另外低ρ(Cd2+)还可促进COD的去除,但Cd2+的加入导致TN去除率下降.
The effects of different mass concentration Cd2+ on simultaneous nitrification and denitrification in SBR with aerobic granular sludge were studied. The experimental results show that: The nitrification reaction can be promoted by low mass concentration Cd2+(0.1 mg/L), but inhibited by high mass concentration Cd2+(more than 3.0 mg/L); The addition of Cd2+ may lead to decrease of denitrification rate and some inhibition effects on the denitr…查看全部>>
