description The invention discloses an oxygenation and adsorption coupled permeable reactive barrier capable of improving the river bank sewage purification capacity and application of the oxygenation and adsorption coupled permeable reactive barrier. The permeable reactive barrier is composed of an adsorption-oxygen release-adsorption layer, the adsorption layer is filled with a rice hull biochar matrix, the enzyme activity and the number of microorganisms of a plant root domain matrix can be improved while pollutants are adsorbed, and the oxygen release layer is composed of a stearic acid-coated slow-release oxygen agent and slowly releases oxygen, so that the oxygen release effect is improved. The environment with medium and low dissolved oxygen under the condition of high water level is improved, oxygen is provided for plants and microorganisms, indigenous microorganisms are promoted to rapidly grow, and pollutants in the water body are thoroughly degraded. According to the system, the river bank is properly transfor
