Ternary micro-electrolysis ceramsite-permeable reactive barrier for repairing underground water and application of ternary micro-electrolysis ceramsite-permeable reactive barrier

The invention discloses a ternary micro-electrolysis ceramsite-permeable reactive barrier for repairing underground water and application thereof, and belongs to the technical field of underground water remediation, the reactive barrier comprises a first chamber, a second chamber and a third chamber which are arranged in sequence; the first chamber and the third chamber are filled with an adsorption medium; and the second cavity is filled with nZVI/Al/C ceramsite. The invention also provides an application of the ternary microelectrolysis ceramsite-permeable reactive barrier for repairing underground water in repairing organic pollution of underground water. According to the invention, not only can the adsorption of pollutants be realized, but also organic pollutants such as PFOA in underground water can be degraded. And moreover, a large amount of reducing agent is not needed, and the required raw materials are fewer, so that the cost is lower. And meanwhile, granulation is performed through high-temperature
