The invention discloses a single river channel inner overflow water environment treatment system and a method. Water in a water inlet river reach is lifted to a high place under the effect of power supplied by a power pump, and is ejected by a water outlet pipe; the water is fully contacted with air for aeration, is ecologically purified through a wetland or an ecological floating bed or a combination of the two, and flows back into the other end of a treatment river reach in a weir flow manner to form a planar ring current, so that the river fluidity is improved, the river dissolved oxygen level and the water environmental capacity are improved; the river flowing speed is controlled by a flow control valve; electric power of the power pump and removable pump is complemented and supplied by a solar panel, a wind driven generator and a self-prepared power supply under control of a power distribution unit; and such pollutants as sludge at the bottom of a purification pool are cleaned termly through the movable desilting pump to improve the river water quality. The single river channel inner overflow water environment treatment system and method are prominent in economic and social benefits, and is higher in research and popularization value under the background of rapid urbanization development and energy and water environment crisis.
