The anaerobically treated leachate from municipal solid waste incineration plant usually contains extremely high ammonium nitrogen concentrations and relative low COD/N. The effluent of digester was first treated by (partial or full) nitrification and then processed by Anammox-DAMO to remove nitrogen. The methane produced from anaerobic biotreatment can be used as electron donors for DAMO process. This project contains the following four sections.1) focus on the mechanism of accelerating electrons transfer from CH4 to DAMO archaea and from DAMO archaea to NO3-/Anammox in order to achieve the enrichment of DAMO archaea and the enhancement of their biological activities, 2) discuss the effect of different electron accepters (NO2- or NO3-) and operating load on the stability of processing system, thereafter select the optimal operation mode. 3) study the influence and mechanism of fulvic acid from leachate on the treatment performance, 4) investigate the nitrogen transformation and metabolic pathway in combined process, and analyzes the key rate-limiting step. Through the study on optimizing the system operation, the control strategy of combined process treating incineration leachate would be proposed, which solves the problems existed in Anammox process of limited NO2-/NH4+ in influent and low total nitrogen removal rate due to high concentrations of nitrate in effluent. This project provides scientific basis to achieve economical and efficient nitrogen removal treatment of incineration leachate.
