摘要
在以氨氮去除率为指标,在振荡时间60 min,振荡温度25℃,振荡速度140 r/min的条件下发现凹凸棒土的最佳投加量2.5 g;添加凹凸棒土可以加强SBR生物系统去除氨氮的能力;拟合凹凸棒土吸附氨氮的等温线方程符合Freundl-ich吸附模型。
With an indicator of removal rate of ammonia nitrogen,under the condition of oscillation time of 60 min,oscillation temperature of 25 ℃ and oscillation speed of 140 r/min,the optimized dosage of attapulgite was found to be 2.5 g by experiments.The capacity of the biological SBR system for absorption of ammonia nitrogen could be enhancecd by adding attapulgite.The fitted isotherm equation of attapulgite for absorption of ammonia nitrogen accords with the Freundlich absorption model.
