Abstract

The invention discloses a biogas slurry modification technological method, relates to the field of biogas slurry treatment. The biogas slurry modification technological method comprises the followingsteps of first, biogas slurry preparation; second, oxidization modification; third, secondary catalytic reaction; and fourth, flocculating setting. The invention further discloses a technology and a device of biogas slurry catalytic oxidization modification. A micro-nano bubble generator is arranged at the bottom of a catalytic oxidization reaction tank. An ozone catalyst fixed bed is arranged above the micro-nano bubble generator. Catalyst is granular and has the gap filling rate of 30% or more. A nano-iron mediate ultrasonic device for stir is arranged in a secondary reaction tank closely connected with the oxidization reaction tank. According to the biogas slurry modification technological method, biogas slurry deodorization and secondary decomposition of antibiotics and organic matterin the biogas slurry are carried out quickly in a catalytic ozonation manner, metal ions in biogas slurry are oxidized, the biogas slurry is lower in viscosity because of modification, the valence ofmetal ions is increased, and because of flocculating setting, it is achieved that biogas residues and partial metal salt are removed.

Description

technical field [0001] The invention relates to the field of biogas slurry fertilizer processing, in particular to a biogas slurry modification process method. Background technique [0002] For thousands of years, the biogas slurry after the fermentation of organic matter into biogas has been used as fertilizer to realize the cycle of organic matter in nature. In recent years, due to the large-scale use of feed additives in large-scale farming, and the presence of grease and salt in kitchen waste, the biogas slurry after anaerobic biogas generation such as livestock and poultry manure and kitchen waste has become difficult wastewater, which needs to be treated Even if it does not contain feed additives, oil and salt, the anaerobic biogas slurry emits a foul smell, which makes the biogas slurry cause air pollution during storage, transportation and use, making people uncomfortable, and the suspended organic matter that is not completely degraded forms a dura on the surface ,...
