Technical method for biological fermentation of liquid dung and biogas slurry

Abstract

The invention relates to a technical method for biological fermentation of liquid dung and biogas slurry, which comprises the following steps: 1, preparing raw materials and tools for biological fermentation of liquid dung and biogas slurry; 2, performing aerobic deodorized fermentation; and 3, performing anaerobic fermentation optimized treatment. According to the technical method for biological fermentation of liquid dung and biogas slurry, secondary fermentation is performed on liquid dung and biogas slurry, so that harmful pathogenic bacteria can be thoroughly decomposed and phagocytized, and the liquid dung and biogas slurry can be changed into a beneficial biological liquid fertilizer, thereby thoroughly solving the problem on pollution caused by the liquid dung and biogas slurry.

Description

technical field

[0001] The invention relates to a biological fermentation technology method of dung water and biogas slurry. Background technique

[0002] At present, the livestock and poultry breeding industry in our region is rapidly developing in the direction of intensification and high efficiency. However, the environmental pollution caused by the large amount of manure and sewage produced by intensive farms every day has become a restrictive factor for its development. At present, the treatment method of feces and urine sewage is complex in process, large in investment, and high in water consumption. In particular, the treatment and utilization of feces are difficult, and harmful bacteria cannot be eliminated, which is easy to cause environmental pollution and epidemic diseases; followed by untreated feces and urine The application of sewage into the farmland will cause soil pollution, reduce the air permeability and water permeability of the soil and harden it, seriou...
