The invention discloses a modularized detachable constructed wetland, which is formed by a plurality of wetland modules, each module is relatively independent, and the module comprises a plurality of detachable filler units; each filler unit consists of a filler frame, a net separator and a filler layer, and the filler layer comprises a soil layer, a soil separation layer and a porous light filler layer from top to bottom. According to the water quality, the water yield and the water outlet requirement of the treated sewage, the wetland modules can be connected in series and in parallel or compositely connected to constitute a constructed wetland system. The modularized detachable constructed wetland has a simple structure, is convenient to install, is low in cost, and adapts to industrialized batch production. In the operation process of the wetland, the wetland modules and the filler units can be replaced and repaired at any time, the system is not blocked easily, the treatment effect is good, and the land
