The invention aims to develop an efficient sewage deep treatment system according to the characteristics of secondary effluent quality of municipal wastewater to reduce pollution of sewage to the environment, increase the circulation utilization rate of water and create better environmental benefits, social benefits and economic benefits. According to an integrated ozone coupled ceramic membrane type MBR (membrane bioreactor) and treatment process, the system comprises an ozonization reaction zone (1), an anoxic reaction zone (2), an anaerobic reaction zone (3), aerobic ceramic membrane type MBRs (4), a backwashing water tank (5), a ceramic membrane assembly (6), a water inlet pump (7), an ozone generator (8), an oxygen bottle (9), a sludge reflux pump (10), an effluent pump (11), an air blower (12), gas flowmeters (13), water check valves (14), an electromagnetic valve (15), a tail gas treatment device (16), an inner reflux pump (17), a time controller (18), a sand core filter plate (19), a flowmeter (20), an electromagnetic valve (21) and a time controller (22). The reaction device and process mainly comprises an ozonization process, an anoxic-anaerobic-aerobic biological treatment process and a membrane filtration process. Ozonization is coupled with biological treatment and membrane filtration for treatment of secondary effluent of municipal wastewater, and macromolecular organic components, nitrogen, phosphorus and other pollutants which are difficult to degrade are effectively removed.
