Biogas-fermentation settling pond

Abstract

A biogas fermentation sedimentation tank, comprising a rectangular pool body, the pool body includes a central wall and a partition, the central wall is arranged on the center line of the pool body along the square shape of the pool body, and only one end of the central wall body is connected to the pool body Connected, there are multiple partitions perpendicular to the central wall in the pool body, which divide the pool body into multiple sedimentation units, and the adjacent two partitions are respectively connected with the central wall or pool body, so that the two sedimentation units The entrances of the pool are staggered, and a filter plate is set between each partition and the pool body or the central wall, and a row of liquid through-holes are set on the filter plate; A liquid inlet pipe and a liquid discharge pipe, the liquid inlet pipe is provided with a control valve. Compared with the prior art, the present invention has significant advantages and beneficial effects: the excrement and sewage pass through the sedimentation units arranged in a staggered manner, which increases the flow distance, improves the sedimentation effect, and reduces the occupied area; the central wall is provided with a walking platform, which is convenient for daily use. management and maintenance.

Description

technical field [0001] The invention belongs to the field of biogas fermentation, in particular to a biogas fermentation sedimentation tank. Background technique [0002] At present, due to the implementation of new energy projects in rural areas, biogas projects are gradually being promoted across the country, and the rational and effective use of biogas slurry and biogas residues in many areas has enabled agricultural production to embark on an ecology of saving costs, improving quality, increasing production, and increasing efficiency. Environmentally friendly development path, its utilization market is huge. In the prior art, the treatment of manure and sewage is mostly through sedimentation, so that the heavy objects and light objects in the wastewater are separated, and the separated two substances are treated separately. At present, the treatment of manure and sewage often uses multiple sedimentation tanks to settle sequentially, and the civil engineering is large. M...

Problems solved by technology

In the prior art, the treatment of manure and sewage is mostly through sedimentation, so that the heavy objects and light objects in the wastewater are separated, and the separated two substances are treated separately. At present, the treatment of manure and sewage often uses multiple sedimentation tanks to settle sequentially, and the civil engineering is large. And it occupies a large area, it is not easy to control the flow rate of fecal sewage, resulting in poor sedimentation effect, and then requires more sedimentation tanks for sedimentation, which increases the cost of fecal sewage treatment
