Further, described feed pipe stretches into the part of described housing and is provided with dispersal of feed device.
Further, the overall cylindrical barrel-like structure of described housing.
Further, the overall V-shaped groove-like structure of described sludge bucket.
Further, described sludge bucket is flat.
Further, described discharge nozzle is arranged on described housing central section, which is provided with discharging control valve.
Further, described appendix is arranged on described case top, which is provided with natural pond gas control valve.
Have employed technique scheme, the invention have the benefit that
Biogas fermentation and biogas residue precipitation dual-use function can be realized, by multiple sludge buckets, it is possible to effectively precipitate biogas residue, biogas fermentation and biogas residue two functions of precipitation and realize simultaneously inside same device, it is possible to effectively reduce construction investment and save project occupation of land simultaneously.
