NOVELTY - An anaerobic device driven by solar energy to agitate comprises water inlets (1), agitators, a packing area, baffle plates (4), water outlet (5), a storage battery (6) and a solar panel (7). The water inlets are arranged on one sidewall in middle of the upper part of device body. The agitator, the packing area and the baffle plates are installed inside the device body. The water outlet is arranged on other sidewall in the middle of upper part of device body. The solar panel is connected with the storage battery which is connected with the agitators to form a solar agitating system.    USE - Anaerobic device for treating sewage (claimed).    ADVANTAGE - The device has good hydraulic mixing state, sludge retention capability and excellent decontamination capability; and is capable of making sufficient contact reaction of sewage with microorganism in a reactor. The solar energy used as motive power of agitators is capable of efficiently utilizing natural resource and lowering operation cost.    DETAILED DESCRIPTION - An anaerobic device driven by solar energy to agitate comprises water inlets (1), agitators, a packing area, baffle plates (4), water outlet (5), a storage battery (6) and a solar panel (7). The water inlets are arranged on one sidewall in middle of the upper part of device body. The agitator, the packing area and the baffle plates are installed inside the device body. The water outlet is arranged on other sidewall in the middle of upper part of device body. The middle part of the device body is the packing area, and the agitators are arranged below the packing area. The baffle plates are as wide as the device body, alternately and vertically arranged in parallel and at intervals up and down. The solar panel is connected with the storage battery which is connected with the agitators to form a solar agitating system.
