        Our group’s researches mainly aimed at the development of advanced treatment of complicated organic wastewater and simultaneous resource recycling and energy regeneration. In order to achieve this goal, extensive effort has been devoted to exploring and designing advanced materials, treatment processes and equipments. Meanwhile, the understanding of the relationship between the composition/structure of the catalysts and their activity was systematically studied. On this basis, a few novel build-up technologies via coupling photocatalysis, conventional advanced oxidation and biochemical methods was developed. The synergistic effect of these cooperated technologies as well as their catalytic mechanisms on organic pollutant degradations were deeply studied. Noticeably, such combined technologies not only conquered the degradation difficulties of complicated organic wastewater with high concentration but also made full use of the complicated organic wastewater for simultaneous resource recycling and energy regeneration. Until now, the innovations in a certain aspects of theories, wastewater treatment methods, technological design and equipments have been achieved in our group. And the coupled techniques have already been adopted in many sewage wastewater plants to treat various kinds of organic wastewaters, such as complicated domestic wastewater, landfill leachate, pharmaceutical wastewater and hyper-saline organic wastewater, producing great environmental, economical and social benefits.
