The invention relates to a backwash and an aeration type subsurface flow wetland water purification equipment and a water purification method. Purification tank is cubic box body arranged in the middle of the wall separating purification tank will be divided into downlink and uplink downlink pool pool, pool and pool upstream homogeneous filling filling medium, plant species of amphibious amphibious tank top, top down pipes, the upper level is higher than the upper end of the adjusting pool purification treatment pond. One side of the water tank, regulating water inlet pipe and water diversion water pipe and the outlet pipe is arranged on the uplink receiving pool side, purification treatment pond aeration machine set. The present invention has high loading rate, small occupied area, good treatment effect, nitrogen and phosphorus removal ability, resistance to impact load, not easy to breed mosquitoes, has the advantages of convenient management, operation of infrastructure and operation low cost of maintenance, the water flow on the ground below, the health condition is good, the sewage in the process was repeated after anaerobic process and the maximum oxygen consumption, improve treatment effect.
