Comprehensive treatment method of wastes in slaughtering process of meat duck

Abstract

The invention discloses a comprehensive treatment method of wastes in the slaughtering process of a meat duck, which comprises the following steps: firstly, fermenting the discharged solid wastes to generate methane; and secondly, using discharged sewage to purify artificial wetlands. By adopting the method, matters and resources among industries are utilized in a cascade manner, a biomass industry chain is lengthened, and the pollution of pollutants to meat products and the damage to human health are efficiently controlled, so that the standardization production is achieved, and the food hygienic quality is ensured. The comprehensive treatment method forms a coexisting and interdependent industrial ecological chain, so that biological resources are optimally configured, and the economic and ecological multiplication effect is converted, thereby having good social benefit and economic benefit.

Description

technical field [0001] The invention relates to a method for treating waste in the process of slaughtering animals, in particular to a method for comprehensively treating waste in the process of slaughtering meat ducks. Background technique [0002] In the process of animal slaughter, a large amount of solid waste will be produced, and a large amount of sewage will be discharged at the same time. Such a large amount of waste not only occupies a large amount of land, but also causes serious pollution to the surrounding environment. Usually, in the process of slaughtering animals, especially meat ducks, a lot of hot water is needed, and a large amount of coal is burned, and the burning of coal produces a lot of harmful gases, which also causes some pollution to the air. At present, there is no practical and effective method to comprehensively treat the waste generated in the slaughtering process. Contents of the invention [0003] The object of the present invention is to p...
