Problems solved by technology

[0002] Due to insufficient funds and weak related technologies, the enterprise has been lagging behind in the treatment of manure. With the continuous expansion of the scale of the enterprise, the pollution problem has gradually become prominent. The pollution can affect the living and ecological environment, and also restricts the development and growth of the breeding enterprise.

Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] Such as figure 1 The USR fermentation process shown is to pretreat pig manure and sewage in the treatment tank. After the preliminary treatment, it is acidified and hydrolyzed in the acidified hydrolysis tank, then precipitated in the sedimentation tank, adjusted and measured, and fermented in the anaerobic fermentation tank. Fermentation is carried out at a fermentation temperature of 35°C for 15 days, and the virus killing rate is over 96%. The biogas, biogas residue and biogas slurry produced after fermentation are separated, and the biogas residue is used to produce organic fertilizer for use in farmland and orchards, etc., and the biogas slurry is stored in In the biogas slurry tank, the biogas enters the condenser through the desulf...

Abstract

A USR (Upflow Solids Reactor) fermentation technology method belongs to the technical field of a fermentation technology. A USR fermentation technology is adopted; organic matters and ions capable of stimulating growth of crops are refined from feces of livestocks and poultry by fermentation, and methane is applied to living electricity utilization and production electricity utilization at the same time. According to the USR fermentation technology method, harmonious development of organisms, an ecological environment, energy sources and an economic benefit is facilitated; circulation factors are added; a biologic chain and a benefit chain are prolonged; living and ecological environments are improved; a radiation function is enhanced; and an enterprise is driven to change into ecotypic production integrated with breeding, cultivating and processing from original cultivation, so that the economic benefit of the enterprise is improved, and advantages are created for expanded reproduction of the enterprise.

Description

Technical field: [0001] The invention relates to a USR fermentation process and belongs to the technical field of fermentation processes. Background technique: [0002] Due to insufficient funds and weak related technologies, the enterprise has been lagging behind in the treatment of manure. With the continuous expansion of the scale of the enterprise, the pollution problem has gradually become prominent. The pollution can affect the living and ecological environment, and at the same time restricts the development and growth of the breeding enterprise. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a USR fermentation process. [0004] The technical problem to be solved by the present invention is realized by the following technical solutions. [0005] The USR fermentation process is characterized in that: [0006] (1) Pretreatment of pig manure and sewage in the treatment tan...
