Her research focuses on anammox biotechnology, which is cost-effective and needs less energy for removing nitrogen from wastewater. Although this technology has been investigated for more than ten years, the stringent metabolism conditions and extremely slow growth rate of the anammox bacteria have restricted its application to pilot-scale plants. To solve these problems, her work was performed with the anammox consortium; including the corresponding strategies to shorten the start-up period of anammox process in via of enhancing the anammox bacteria activity, as well as the basic mechanisms of multi-species coupling processes based on anammox to enlarge the application scale of anammox process. Major progresses include: (1) the discovery of new species, named Anammoxoglobus sulfate, to perform the NH4+-N oxidization with SO42- deoxidization to produce NO2—N, and the development of coupled processes based on anammox for the nitrogen removal from wastewaters containing urea, sulfate and high salinity; (2) the application of physical energy fields, including magnetic field and electric field, to increase the anammox process performance, which is also useful for fast start-up of anammox process since it is proved as a convenient approach to enhance anaerobic ammonium oxidizing activity;  (3) the start-up of single-stage anammox-based bioreactors for treating reject-water produced in Munich wastewater treatment plant, and (4) the inveitgation into the biomass profile, optimal parameters and treatment performance of the anammox based process in different geometrically biofilms by AQUASIM 2.1 software. Guide the upgrading of conventional wastewater treatment plant by nitrification and denitrification process to novel anmmox-based process.
