A solid waste treatment pool

Abstract

The invention discloses a solid waste treatment pool. The solid waste treatment pool comprises: a pool body; a treatment chamber; a liquid collection chamber, which is used for collecting excess biogas slurry in the treatment chamber, is disposed below the treatment chamber and can move up and down relative to the treatment chamber; an infusion component, which is used for communicating the treatment chamber and the liquid collection chamber, and includes a first liquid channel and a second liquid channel disposed under the first liquid channel; and an open-close device, which can close or open the second liquid channel. When the liquid collection chamber moves from the bottom up, the open-close device opens the second liquid channel for conveying of the liquid from the liquid collection chamber to the treatment chamber. When the liquid collection chamber moves from the top down, the open-close device closes the second liquid channel. According to the invention, the treatment chamber is equipped with the first liquid channel and the second liquid channel, so that biogas slurry can flow back into the treatment chamber through the first liquid channel and the second liquid channel, the backflow speed is fast, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of solid waste reuse, in particular to a solid waste treatment pool. Background technique [0002] In rural areas, a large amount of solid waste is often produced, such as agricultural straw; the traditional treatment method is usually to produce biogas by crushing and fermenting, and then use earthworms to process the biogas residue to prepare organic fertilizer. Due to the extremely fast reproduction speed of earthworms, it is easy to have an excessively high density of earthworms in this way, so the earthworms need to be separated regularly. [0003] The traditional separation methods are feed induction or strong light irradiation, which consume a lot of resources and take a long time. In order to solve the above problems, it appears that the biogas slurry collected during the treatment process is returned to the treatment chamber, so that the earthworms drill out to the water surface, and then the earth...

Problems solved by technology

[0004] However, in this method, the waste liquid is usually pumped into the treatment chamber through pipelines and power pumps, and after the earthworms are separated, the waste liquid is pumped out of the treatment chamber, which consumes a lot of energy, takes a long time, and is inefficient.
