The invention relates to the field of environmental protection apparatuses, and concretely relates to a mixed filler fluidized tank coupled constructed wetland sewage advanced treatment apparatus. Sewage sequentially flows through an anaerobic tank, a fluidized tank, a sedimentation tank, a primary wetland, a phosphorus removal tank and a secondary wetland; a flexible fiber rope filler is arrangedin the anaerobic tank, the fluidized tank is provided with a moving bed and a porous polymer mixed biological filler and can realize fluidized movement, a gravel and quartz stone filler is arranged in each of the primary wetland and the secondary wetland, and wetland plants are planted in each of the primary wetland and the secondary wetland; and an aeration tube is arranged in the fluidized tank, and is externally connected with an aeration control device, a return tube is arranged in the sedimentation tank and is externally connected with a return pump control device, and the control devices realize automatic control in a numerical control switch operation mode. The apparatus overcomes the deficiencies in the prior art, is obtained by innovating the universality of a traditional anaerobic, aerobic and ecologic sewage treatment technology, has the advantages of novel process, compact structure, high space utilization rate, small occupied area, enhancement of nitrogen and phosphorus removal, and stable water discharge, and has great promotion and application values.
