Papermaking wastewater aeration device

Abstract

The invention discloses a papermaking wastewater aeration device, which comprises a transverse pipe, wherein the top of the transverse pipe is fixedly connected with a wide plate; the inner wall of the wide plate is fixedly connected with a first bearing; the inner wall of the first bearing is provided with a filtering mechanism; the left side of the transverse pipe is fixedly connected with an aerator; and the right side of the top of the transverse pipe is provided with an opening and closing mechanism. According to the papermaking wastewater aeration device, the problem that the existing papermaking wastewater aeration device cannot quickly combine oxygen with wastewater during operation is solved through an agitation mechanism, so that microorganisms can quickly obtain dissolved oxygen, the wastewater treatment time is reduced, and the treatment effect is ensured; and the problem that a filter screen for filtering oxygen is inconvenient to replace is solved through the filtering mechanism, the papermaking wastewater aeration device does not need to be stopped during replacement, the wastewater is continuously treated, and the wastewater pollution is reduced, and the problem that the input amount of the oxygen cannot be controlled is solved through the opening and closing mechanism during replacement, so that the oxygen waste is avoided, and the practicability is improved.

Description

Technical field [0001] The invention relates to the technical field of aeration devices, in particular to a papermaking wastewater aeration device. Background technique [0002] The aeration device refers to artificially injecting air into the biochemical aeration tank through appropriate equipment to achieve the desired purpose. Aeration not only makes the liquid in the tank contact with the air and oxygenates, but also accelerates the oxygen in the air to the liquid due to agitating the liquid. Transfer to complete the purpose of oxygenation, but the existing papermaking wastewater aeration device cannot quickly combine oxygen with wastewater during operation, resulting in microorganisms unable to quickly obtain dissolved oxygen, increasing the wastewater treatment time and affecting the treatment effect. In addition, the oxygen filter screen is not convenient to replace. The device needs to be stopped during replacement, resulting in the inability to treat wastewater, making w...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a papermaking wastewater aeration device to solve the problem that the existing papermaking wastewater aeration device cannot quickly combine oxygen and wastewater during work, resulting in the inability of microorganisms to quickly obtain dissolved oxygen. The treatment time of wastewater is increased, which affects the treatment effect, and the filter screen for filtering oxygen is inconvenient to replace. When replacing, the device needs to be stopped, which leads to the inability to treat wastewater and serious wastewater pollution. A large amount of oxygen is wasted and the practicality is reduced
