Abstract

The invention relates to a multi-cycle composite bioreactor and a process thereof. The multi-cycle composite bioreactor comprises an anaerobic zone, an anoxic zone, a first synchronization zone, a second synchronization zone, a first aerobic zone, and a second aerobic zone. The process of the multi-cycle composite bioreactor adopts multi-cycle design and composite sludge film coexistence design, comprises an anoxic / anaerobic cycle, a synchronization zone internal cycle, an aerobic zone internal cycle, an anoxic zone / aerobic zone mixed liquid backflow cycle, and a sludge backflow cycle, facilitates enrichment of denitrification dephosphorization bacteria and realization of synchronous nitrification and denitrification, improves the efficiency of denitrification and dephosphorization, and is low in running energy consumption, and flexible in control mode.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and relates to a sewage treatment device, in particular to a multi-circulation composite bioreactor and a process thereof. Background technique [0002] Anaerobic-anoxic-aerobic process (A 2 The activated sludge process represented by O process) is widely used in existing urban sewage treatment plants in my country due to its advantages of simple structure, short total hydraulic retention time, small control complexity, and not easy to produce sludge bulking. but A 2 The O process has some problems such as substrate competition, sludge age contradiction, and difficulty in improving the total nitrogen removal rate. Simultaneous nitrification and denitrification and denitrification phosphorus removal technologies can effectively improve A 2 O process efficiency. [0003] The traditional theory holds that the removal of nitrogen is realized through two independent processes of nitrification and d...
