Abstract

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.
