The invention relates to an artificial wetland sewage pretreatment apparatus. The apparatus comprises a water inlet river channel formed by a splayed baffle wall, and an artificial wetland sewage pretreatment device connected with the water inlet river channel; the water inlet river channel is provided with a baffle wall device; the baffle wall device is formed by a baffle dam and a screen; the baffle dam is fixedly connected to the bottom of the water inlet river channel; and the screen is fixedly connected with the top of the baffle dam. The artificial wetland sewage pretreatment apparatus has the following beneficial effects: the height of the dam body is determined according to the lowest water level of the river channel in the dry season, so the flow at the upper portion of the dam body is not influenced, the inlet water flow of a wetland is guaranteed, and low-speed sedimentary sand can be blocked from entering the wetland pretreatment part; and large river floaters intercepted by the screen are the mai
