The technical scheme adopted by the utility model for solving the technical problems is to provide a novel anaerobic reactor for reforming old projects, which comprises an anaerobic reactor body, a vertical stirrer, a precipitation module and a water distributor; the vertical stirrer is divided into an upper double-layer stirrer and a lower double-layer stirrer, the upper end of the vertical stirrer penetrates through the upper end cover of the anaerobic reactor body and is connected with a stirrer motor, the precipitation module is fixedly connected to the anaerobic reactor body through a support, the fixed position of the precipitation module is higher than the upper-layer stirrer of the vertical stirrer, and the upper end of the precipitation module is connected to the water outlet pipe; the water distribution pipe is arranged at the bottom of the anaerobic reactor body, and an inlet of the water distribution pipe is connected to the water inlet pump; the upper end cover of the anaerobic reactor body is connected to a biogas collecting pipe.

Furthermore, the water distribution pipes are arranged in a branched manner, end sockets are mounted at the ends of the water distribution pipes, round holes are uniformly formed in the water distribution pipes, the distance between the round holes is 200mm, and the hole forming positions of the round holes are 45 degrees downward relative to the vertical center line of the water distribution pipes.

Further, the diameter of the round hole is phi 20 holes.

Further, the precipitation module is welded on the anaerobic reactor body through a bracket.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses an increase mechanical stirring and deposit the module and reach the effect that anaerobic reactor transformed, it is simple to transform the installation, and the treatment effect is good.

2. The utility model discloses increase double-deck vertical agitator, guarantee to get into anaerobic reactor's sewage and the abundant contact of anaerobic sludge of reactor to change the pollutant into the value that methane reduces aquatic COD through anaerobic sludge.

3. The utility model discloses increase and deposit the module, when mud, the muddy water separation behind the module of deposiing of water mixture, the anaerobism mud flows back in the reactor, and the rivers of separating go out anaerobic reactor.

4. This patent reforms transform fast, effectual, is applicable to the anaerobic reactor transformation of various pond types.
