Resource comprehensive utilization device used for treating animal dung

Abstract

The invention belongs to the field of treatment of dung in large-scale animal farms and in particular relates to a resource comprehensive utilization device used for treating animal dung. The device comprises a biogas generating unit, a septic unit and a separation tank, wherein the biogas generating unit comprises at least a biogas tank, the upper sides of the biogas tanks are covered by a transparent plastic film, gas collection and storage units covering fermented matters in the tanks are also arranged in the biogas tanks, and the fermentation residues in the biogas tanks are discharged into the septic unit; the septic unit comprises at least a septic tank, and the liquid in the septic tank is discharged into a discharge unit; the separation tank is used for carrying out solid-liquid separation on the liquid flowing into the separation tank, and an outlet is formed in the wall of the separation tank. The device has a simple structure, is low in manufacturing cost, is convenient to popularize and use in vast regions in the countryside, simultaneously can be normally used in winter, and ensures the yield of biogas.

Description

technical field [0001] The invention belongs to the field of excrement treatment of large-scale poultry and livestock farms, and in particular relates to a resource comprehensive utilization device for processing poultry and livestock excrement. Background technique [0002] In the prior art, for the treatment and utilization of livestock and poultry manure, there are mainly the following methods: [0003] The first is the incineration method, which uses waste incineration treatment technology to ash it at 800-1000°C, and the heat generated is used for power generation, etc., to achieve the purpose of reducing and killing harmful pathogens. This method requires large investment, expensive treatment costs, and produces a large amount of harmful gases during the treatment process, making it difficult to apply and promote. [0004] The second is the drying method, which mainly includes natural drying, high-temperature rapid drying, drying and expansion drying, mechanical dryin...
