NOVELTY - High concentration municipal sludge anaerobic digestion processing device comprises an anaerobic digestion unit, an anoxic digestion unit and ferric oxide filtering unit. A shell of the processing device is internally provided with a fixed-separated diffusion layer that is divided into the anaerobic digestion unit and the anoxic digestion unit. The positive and negative electrode distributed in the anaerobic digestion unit and the anoxic digestion units are separated by the diffusion layer. The anaerobic digestion unit is provided with an anion and cation exchange resin mixed column.    USE - The processing device is useful for anaerobically digesting high concentration sludge.    ADVANTAGE - The processing device reduces the adverse effects of the accumulated acid metabolic products on the associated microbial activity during the anaerobic digestion process.    DETAILED DESCRIPTION - High concentration municipal sludge anaerobic digestion processing device comprises an anaerobic digestion unit, an anoxic digestion unit and ferric oxide filtering unit. A shell of the processing device is internally provided with a fixed-separated diffusion layer that is divided into the anaerobic digestion unit and the anoxic digestion unit. The positive and negative electrode distributed in the anaerobic digestion unit and the anoxic digestion units are separated by the diffusion layer. The anaerobic digestion unit is provided with an anion and cation exchange resin mixed column. A sludge inlet and a sludge discharge port are respectively set on two side walls of the anaerobic digestion unit. A water inlet and a water outlet I are respectively arranged on two side walls of the anoxic digestion unit. The water outlet I is connected with the ferric oxide filtering unit and a water outlet II. An INDEPENDENT CLAIM is also included for using the high concentration municipal sludge anaerobic digestion processing device, comprising adding the sludge to be processed into the anaerobic digestion unit, adding recyclable anion and cation exchange resin into the mixed column located in the anaerobic digestion unit supplemented by the anoxic digestion unit, applying a low-direct current voltage between the anaerobic digestion unit and anoxic digestion unit, weakening the acid metabolic products accumulated in the anaerobic digestion unit, and improving system stability of municipal sludge high concentration anaerobic digestion.
