Animal slaughter house garbage treatment method and device thereof

Abstract

The invention discloses an animal slaughter house garbage treatment method, which comprises the following steps: firstly, mixing and crushing slaughter house garbage and green feed, then feeding the crushed mixture and a hydrolysis solution into a biogas digester together, and fermenting in an environment of 45-58 DEG C; collecting biogas generated after fermentation of the mixture, mixing the biogas and combustion-supporting gas and combusting, and providing part of heat generated by combustion for a biogas digester to be heated; and discharging the mixture after the fermentation is finished,and drying at high temperature to form the soil conditioner. The slaughter house garbage and a green feed are mixed and fermented, so that the fermentation efficiency of the slaughter house garbage in the mixture can be effectively improved, and the gas production rate is further improved; by optimizing the structure of the treatment device, the fermentation efficiency of mixed materials can be further improved, and the treatment difficulty of garbage after fermentation is reduced.

Description

technical field [0001] The invention relates to a treatment method for animal waste, in particular to a treatment method and a treatment device for animal slaughterhouse waste. Background technique [0002] Animal slaughterhouses and seafood markets produce a large amount of animal waste such as animal and aquatic viscera, minced meat, shrimp shells, and fish bones in the daily production and sales process. The traditional way to deal with this type of waste is to collect the waste and landfill it Or burning treatment, but the way of landfill will cause waste of resources, and mixed combustion as fuel with other garbage will easily reduce the calorific value of the fuel, and there is a possibility of dioxin release, and the environmental protection effect is low. With the development of technology, fermenting perishable waste to produce biogas has become a new waste treatment method. Compared with combustion treatment, this method can effectively reduce the output of harmful...

AI Technical Summary

Problems solved by technology

However, at present, most of the garbage used for biogas fermentation is food waste with high biogas production efficiency, such as leftovers, vegetables and fruits, and expired food. Compared with food waste, animal slaughterhouse waste has slower gas production and garbage in the environment. The problem of easy deposition of crusts during the fermentation process reduces the efficiency of waste treatment and increases the difficulty of biogas residue removal

However, due to the existence of the above problems, the waste from animal slaughterhouses cannot be processed by fermentation and biogas production, which reduces the resource utilization rate of waste from slaughterhouses.
