摘要：

This thesis put forward the treatment concept of "without Biomass Retention Sequential Batch Intensified Pretreatment (WSIP)" in leachate treatment, for sake of improving performance of nitrogen removal, optimizing excess water's nutritional ratio and benefitting the follow-up aerobic biological treatment. Based on orthogonal experiment of WSIP Reactor's leachate treatment performance, Conclusions can be drew: the removal performance of ammonia nitrogen and TN is higher of WSIP, in which short-cut nitrification and denitrification can be realized; HRT, DO and sequential period are remarkable factors of ammonia removal performance, TN removal performance and realization of short-cut nitrification and denitrification; In normal temperature, the most perfect functional parameter of WSIP Reactor is: HRT=4d, DO=0.75mg/L and sequential period is 6h.
