A device suitable for converging and extracting biochemical digestion of overwintering cyanobacteria soil

Abstract

The invention discloses a device combining gathering extraction and biochemical digestion. The device comprises a gathering transmission cabin, an extraction transmission component, a biochemical digestion tank, and a stirring component; the interior of the gathering transmission cabin is provided with a concave portion, the cross section of the concave portion is composed of a rectangle and an inverted isosceles triangle, and one vertex of the triangle forms a lowest place of the gathering transmission cabin; the extraction transmission component is connected with the gathering transmission cabin, and the extraction transmission component comprises a screw transmission member and is arranged in the lowest position; the biochemical digestion tank comprises a tank body skeleton, the tank body skeleton is divided into a first chamber and a second chamber; and the stirring component is arranged in the middle of the first chamber and stirs a material to be treated in the first chamber. Thedevice provided by the invention separates a mud-water mixture through a physical manner, conveys soil with wintering cyanobacteria to the middle through the screw transmission member, conveys the soil with the wintering cyanobacteria upwards through gathering and extraction power members, and returns water located at the upper layer.

Description

technical field [0001] The invention relates to the processing technology of cyanobacteria in aquaculture ponds, in particular to a device for converging, extracting, separating and biochemically digesting. Background technique [0002] In recent years, frequent outbreaks of blue-green algae in major lakes in my country have become the main factor affecting the water quality of lakes. Blue-green algae, also known as blue-green algae, is a simple algal organism. Abundant, rich in nutrients, temperature above 20°C, strong light for a long time, cyanobacteria form air sacs to surface and reproduce rapidly, resulting in the phenomenon of cyanobacteria bloom. After the blue-green algae bloom, a layer of blue-green and foul-smelling foam will be formed on the water surface, which will reduce the light transmission and reoxygenation capacity of the water body, further aggravate the trophication of the water body, and eventually lead to the foul smell of the water body.
