A zero-discharge environment-friendly feed production sewage treatment device

Abstract

The invention discloses a zero-discharge environment-friendly feed production sewage treatment device in the technical field of sewage treatment, which includes a sealed shell, and the inner cavity of the sealed shell is sequentially provided with a degradation chamber, a separation chamber and a filter chamber from left to right. A fermentation chamber is provided at the lower part of the inner cavity of the sealed case, a water inlet pipe is provided on the left side of the sealed case, an air compressor is provided on the right side of the degradation chamber, and an aeration chamber is provided on the right side of the inner wall of the degradation chamber. The left side of the inner wall of the degradation chamber is provided with an electrode sheet, the bottom of the sewage discharge pipe runs through the top of the fermentation chamber, the inner wall of the filter chamber is provided with a guide ring, and the inner cavity of the filter chamber is provided with An annular baffle plate, two sewage discharge pipes with the same structure are arranged at the bottom of the inner chamber of the filter chamber. The present invention fully recycles waste water, can realize zero discharge, protects the ecological environment, and increases treatment efficiency.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a zero-discharge environment-friendly sewage treatment device for feed production. Background technique [0002] In view of the high COD concentration of the wastewater, poor biochemical properties, and many substances that are difficult to degrade in the wastewater, the traditional treatment method is to dig a pool on the ground, and treat the sewage through a series of pool sedimentation and filtration processes. However, this treatment method It occupies a large area and is too expensive. During the treatment process, it is in direct contact with the environment. The smell of wastewater can be blown away by the wind, which is harmful to the environment. At the same time, the treatment capacity of this treatment method is limited, and the treatment efficiency is too slow. Contents of the invention [0003] The purpose of the present invention is to provide a zero-disc...

[0002] In view of the high COD concentration of the wastewater, poor biochemical properties, and many substances that are difficult to degrade in the wastewater, the traditional treatment method is to dig a pool on the ground, and treat the sewage through a series of pool sedimentation and filtration processes. However, this treatment method It occupies a large area and is too expensive. During the treatment process, it is in direct contact with the environment. The smell of the wastewater can drift with the wind, which is harmful to the environment. At the same time, the treatment capacity of this treatment method is limited, and the treatment efficiency is too slow.
