Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1 and 2, the liquid level adjusting device for treating papermaking wastewater of the present embodiment includes a plurality of water tanks 2 disposed at a side portion of an air flotation tank 1, the plurality of water tanks 2 are disposed at equal intervals along a circumferential direction of the air flotation tank 1, a cylinder 3 with two open ends is disposed inside the water tank 2, the cylinder 3 is connected to a driving device 4, a first opening 21 is disposed at a bottom of the water tank 2, a water outlet pipe 5 is disposed below the water tank 2, the water outlet pipe 5 is communicated with the air flotation tank 1, a second opening 51 is disposed in a middle portion of the water outlet pipe 5, the second opening 51 is communicated with the first opening 21, the water outlet pipe 5 is provided with a water outlet, and when the driving device 4 drives the cylinder 3 to move downward and communicate with the first opening 21, a height of normal scum plane 11 in the air flotation tank 1 is consistent with.
In operation, the driving device 4 drives the cylinder to move downwards, the bottom of the cylinder 3 is inserted into the first opening 21, the first opening 21 is communicated with the cylinder 3, and the first opening 21 is sealed. Water to be treated flows into the air flotation tank from a water inlet of the air flotation tank 1, solids in the water float upwards under the action of air flotation to form floating slag which floats on the surface of the air flotation tank 1, the floating slag is scraped into a floating slag groove by a slag scraping device, and the treated water flows into a water outlet pipe 5 from a water outlet of the air flotation tank 1.
