Problems solved by technology

[0002] In the process of animal slaughter, a large amount of solid waste will be generated, 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, 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 for comprehensive treatment of waste generated in the slaughter process

Embodiment Construction

[0012] The comprehensive treatment method for waste in the meat duck slaughtering process of the present invention comprises the following steps:

[0013] (1) Send the discharged solid waste, namely duck viscera, duck blood, duck manure, and duck feathers, into a biogas digester for fermentation to produce biogas; the generated biogas is used for domestic use and a large amount of purified duck meat required in the heating and slaughtering process and the treated water of its viscera;

[0014] (2) The discharged sewage is used for the purification of artificial wetlands; the free water surface artificial wetland treatment system is used to plant plants such as lotus root, cattail and reed on the wetland to beautify the environment and develop the industry of lotus root, cattail or reed.

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.
