Kitchen waste and die-of-disease animal combined treatment technique system

Abstract

A kitchen waste and die-of-disease animal combined treatment technique system mainly comprises a kitchen waste pretreatment system, a die-of-disease animal harmless treatment system, a combined anaerobic fermentation system, a biogas purifying and utilization system, a biogas residue fertilizer making system, a biogas slurry treatment system and a deodorizing system. Organic materials in kitchen waste and wastewater and condensate wastewater in the die-of-disease animal harmless treatment process are subjected to combined anaerobic treatment; generated biogas is purified and then used for power generating and used for a steam boiler, biogas residues are made into compost, part of biogas slurry flows back, and the other part of the biogas slurry is discharged with the standard level; and crude grease extracted from the kitchen waste and die-of-disease animals is used for extracting biodiesel, meat and bone meal obtained after die-of-disease animal harmless treatment is used for bio-fertilizer addition agents, and odors generated in the combined treatment process are discharged with the standard level. According to the kitchen waste and die-of-disease animal combined treatment technique system, the kitchen waste and the die-of-disease animals are treated in a combined mode so as to generate clean energy sources, so that land occupation and investment are saved, the anaerobic fermentation efficiency is improved, significant economic and environmental benefits are brought for the society, and thus the kitchen waste and die-of-disease animal combined treatment technique system has popularization value.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a combined treatment process system for kitchen waste and sick animals. Background technique [0002] Kitchen waste is the domestic waste formed by residents in the process of living consumption, which belongs to urban domestic solid waste. The main components of food waste include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, etc. From the chemical composition, there are starch, cellulose, protein, lipids and inorganic salts. Food waste has the following characteristics: high moisture content; high salt content; high organic content; rich in nitrogen, phosphorus, potassium, calcium and various trace elements. [0003] The hazards of food waste mainly include the following aspects: First, it affects the appearance of the city and the living environment. Because food waste is easily corrupted and deteriorated, it breeds germ...

Problems solved by technology

Diseased and dead animals and animal products carry pathogens. If they are not harmlessly treated or disposed of arbitrarily, they will not only seriously pollute the environment, but may also spread major animal epidemics, endangering animal husbandry production safety and social public health safety.
