Aeration tank capable of being automatically opened and closed based on illumination variation and use method thereof

Abstract

The invention belongs to the field of wastewater treatment, and particularly relates to an aeration tank capable of being automatically opened and closed based on illumination variation and a use method thereof. The aeration tank comprises a tank body, a driving cavity is formed in the tank body, two lead screws are rotationally connected in the driving cavity, threaded blocks are in threaded connection with the lead screws, supporting rods are fixedly connected to the two threaded blocks, the upper ends of the two supporting rods penetrate through the driving cavity and are jointly and fixedly connected with a closing cover, the closing cover is of a hollow structure design, a linkage mechanism is arranged between the two lead screws, one side of the tank body is fixedly connected with a liquid storage box, and the liquid storage box communicates with the closing cover through a liquid discharging pipe. Automatic opening and closing of the closing cover can be realized by utilizing the change of day and night illumination in cooperation with the linkage mechanism, the transmission mechanism and the driving mechanism, so that the labor loss caused by manually opening and closing the cover every day is avoided, and the labor cost is greatly saved.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to an aeration tank which can be automatically opened and closed based on light changes and a use method thereof. Background technique [0002] Nowadays, a large amount of wastewater is often produced in the process of industrial production. In order to make the wastewater meet the discharge standard, it is often necessary to treat the wastewater. Aeration treatment is an important step in wastewater treatment. Activated sludge is used in the aeration process. Activated sludge is an aerobic biological treatment method. They aerate sewage for a long time to produce sludge, and the water quality will be significantly improved. [0003] At present, in order to improve the activity of activated sludge, the aeration tank needs to be opened in the state of sufficient light and high temperature during the day, so that the external light and temperature can better act on the ...

AI Technical Summary

Problems solved by technology

[0003] At present, in order to improve the activity of activated sludge, the aeration tank needs to be opened in the state of sufficient light and high temperature during the day, so that the external light and temperature can better act on the aeration tank, so that the activated sludge remains high. At night, as the temperature outside is lower, the activity of activated sludge will decrease, which will affect the treatment of aeration. Therefore, at night, it is often necessary to close the aeration tank to make the aeration The pool maintains a certain temperature so that the activated sludge can continue to purify the sewage better. This makes it necessary to arrange special personnel to open or close the cover of the aeration tank every day, which greatly consumes manpower and increases the cost of employment.
