The invention discloses a sludge and corn straw combined anaerobic digestion system, which comprises a sludge concentration tank, a mixing tank, an anaerobic digestion pipe and a gas storage tank, and the sludge concentration tank, the mixing tank, the anaerobic digestion pipe and the gas storage tank are connected in a sealed welding manner. The method effectively solves the problems of system instability, poor digestion efficiency and low gas yield caused by single anaerobic digestion of low-organic-matter and low-C/N sludge, increases the biogas content, and realizes resource utilization of the sludge, thereby realizing resource utilization of corn straws and reducing the treatment burden of agricultural solid wastes in China. Meanwhile, the system disclosed by the invention is small in occupied area, closed and free of odor gas escape, not only is low in investment cost and operation cost, but also reduces environmental pollution and resource waste, and has important significance on ...
