The invention discloses an integrated efficient biological enrichment wastewater ecological treatment device and method. The device follows the principle of'division of labor, cooperation and best use of everything ', is composed of continuous multi-stage serial sewage biological treatment reactors, and comprises an annular anaerobic zone, a cascade anoxic zone, a multi-stage aerobic zone, a bionic biological filler module, a plant enrichment module and the like. Through biological membranes fixedly growing on plant root systems and artificial biological fillers in the reaction zone and microorganisms suspended in the reaction tank, under the condition of reasonable aeration, organic matters in the sewage are oxidized and decomposed and are converted into stable inorganic matters, gradient change is formed through high enrichment of the organisms, and the sewage treatment efficiency is improved. Therefore, pollutants in the sewage can be efficiently degraded and removed. According to the invention, the biolog
