Abstract

The invention discloses a biogas slurry and biogas residue multistage treatment device and method. The biogas slurry and biogas residue multistage treatment device comprises an equipment shell, solid-liquid separation equipment arranged in the equipment shell and used for solid-liquid separation of biogas slurry and biogas residues, and fermentation equipment arranged in the equipment shell and used for further fermenting liquid obtained after biogas slurry and biogas residues are treated by the solid-liquid separation equipment; the solid-liquid separation equipment comprises first separationequipment, second separation equipment and third separation equipment which are connected in sequence; by means of the first separation equipment, the second separation equipment and the third separation equipment, multi-stage solid-liquid separation of biogas slurry and biogas residues which are waste obtained after biogas fermentation is achieved, separation of the biogas residues and the biogas slurry is achieved more thoroughly, and special utilization of the biogas residues and the biogas slurry can be achieved.

Description

technical field [0001] The invention relates to the technical field of biogas slurry and residue treatment and utilization equipment, in particular to a multi-stage treatment device and method for biogas slurry and residue. Background technique [0002] Biogas fermentation refers to the process in which organic substances are decomposed and metabolized by various microorganisms under certain moisture, temperature and anaerobic conditions, and finally form flammable mixed gases such as methane and carbon dioxide. The biogas fermentation system is based on the principle of biogas fermentation, with the goal of energy production, and finally realizes the comprehensive utilization of biogas, biogas slurry and biogas residue. [0003] As early as 2007, my country began to vigorously develop and support the construction of biogas digesters, especially focusing on rural areas. And in order to increase promotion efforts, the government also introduced a series of subsidy measures. ...
