Description

Pretreatment before sheep manure anaerobic fermentation

Technical Field

The utility model discloses a stockbreeding production technical field specifically is a pretreatment before sheep excrement anaerobic fermentation.

Background

The large and medium-sized biogas engineering is one of important means for solving rural energy supply, and most of the biogas engineering takes livestock and poultry manure such as cow manure, pig manure, sheep manure, chicken manure and the like as raw materials. The sheep manure is an ellipsoidal solid particle with low water content, and is coated with a compact layer which is easy to float on the liquid surface. Due to the different types and feeding modes of the feed adopted by the mutton sheep breeding places, the sheep manure can be mixed with long-fiber forage grass. When the sheep manure is used as biogas, if the sheep manure and the forage grass are not properly pretreated, the sheep manure and the forage grass float on the surface of the liquid, so that the mixing is difficult. When pumps are used for conveying, conveying equipment and pipelines are easy to block. The material distribution system at the bottom of the anaerobic tank is easy to block and is difficult to dredge. The sheep manure and the forage grass float on the liquid surface in the anaerobic tank, the material is obviously layered, and the raw material cannot be fully contacted with the activated sludge, so that the gas production rate of the raw material is low. The sheep manure and the forage grass float on the liquid surface in the anaerobic tank, so that a discharge pipeline of the anaerobic tank is easily blocked. The invention adopts the technical schemes of wetting, crushing, size mixing and the like to solve the problems, thereby having great application and popularization values.
