Abstract

The invention provides a device for producing biogas by two-phase three-section anaerobic digestion of high solids of perishable organic wastes. The device comprises a hydrolysis acid-production reactor and a methane-production reactor, wherein the two reactors are connected with each other, and the bottoms of the reactors are communicated through a circulating pump and a pipe; the hydrolysis acid-production reactor is a solid infiltration bed reactor, the top is provided with a water distributor and a spray header, the middle-upper part is provided with a feeding port, the middle-lower part is provided with a perforated plate and a discharging port, the bottom is provided with a residue-discharging port, and infiltration fillers are arranged on the upper surface of the perforated plate; and the methane-production reactor consists of a filter filler bed and a fiber filler bed, wherein the filter filler bed is arranged on the lower part of the methane-production reactor, the filter filler bed is arranged on the upper part of the methane-production reactor, filter fillers are arranged in the filter bed, a fiber filler frame is arranged in the fiber filler bed, and the fiber filler frame is wound by fiber fillers. The device has the advantages of simple processing procedures, low cost, easy maintenance, stable and reliable performance and suitability for the anaerobic digestion treatment of various perishable organic wastes, and has the capability of producing the biogas in high efficiency and stably by the anaerobic digestion of perishable organic wastes.

Description

technical field [0001] The invention relates to a device for treating organic waste, more specifically, the invention relates to a high-solid two-phase three-stage anaerobic digestion device for producing biogas using perishable organic waste as raw material. technical background [0002] Perishable organic waste mainly refers to perishable and biodegradable waste generated in the process of life and production, including kitchen waste, slops, vegetable, fruit and meat processing waste, etc. Due to the acceleration of urbanization and the improvement of living standards, not only the absolute output of perishable organic waste has increased significantly, but also the proportion of urban post-natal waste has also increased significantly. At present, this part of waste accounts for the total urban domestic waste More than 50% of the amount. The biggest feature of perishable organic waste is the high moisture content and organic matter content, the moisture content is general...
