Nitrogen Removal Performance of without Biomass Retention Sequential Intensified Pretreatment

This thesis is based on Heishizi landfill lechate treatment, contrapose its limitation, and aim at optimizing Without Biomass Retention Sequential Intensified Pretreatment Reactor´s functional parameter and inproving treatment efficiency. Conclusions can be drew that: with HRT´s droping, ammonia nitrogen removal rate decrease, and TN removal rate is highest in case of HRT=5.3d; ammonia nitrogen removal rate increase with aeration time rising, while that of TN is highest in case of aeration time is 9h/d; ammonia nitrogen and TN removal rate increase with temperature rising; ammonia nitrogen and TN removal rate is highest as pH is about 8.0; ammonia nitrogen and TN removal rate is highest as sequential time is about 6.0 hour.
