Problems solved by technology
Due to the limitation of the rare earth disk machine technology and the magnetic properties of the equipment, the circulating water cannot completely separate the suspended particles and oil and other impurities through the rare earth disk. The effective volume becomes smaller, and with the circulation and disturbance of the water flow, suspended solids and other sundries flow into the water supply system, which seriously affects the water quality of the water supply system, and then causes foreign matter to be pressed into the strip, resulting in quality defects
Moreover, in the prior art, the impurities in the advection tank are mainly cleaned up manually after natural precipitation, resulting in higher labor costs
[0003] Therefore, there are technical problems in the prior art that the water treatment method of the advection pool sewage system will reduce the quality of the strip steel produced by hot rolling and consume high labor costs

An embodiment of the invention provides a water treatment method of a horizontal flow tank blowdown system in order to improve the quality of strip steel produced by hot rolling and reduce labor costin water treatment. The water treatment method comprises: collecting circulating water of a horizontal flow tank to a concentrating tank; guiding the circulating water of the concentrating tank to a horizontal-screw centrifuge; adding a preset agent into the horizontal-screw centrifuge, and controlling the horizontal-screw centrifuge to perform impurity separation and separate impurity and circulating water.
Description
technical field [0001] The invention relates to the technical field of water treatment technology in the metallurgical industry, in particular to a water treatment method for an advection pool sewage discharge system. Background technique [0002] The circulating water in the water circulation system of the hot rolling production process is treated by a rare earth disk machine to realize the separation of mud and water. The circulating water enters the turbid ring system and is treated before being reused in production. Due to the limitation of the rare earth disk machine technology and the magnetic properties of the equipment, the circulating water cannot completely separate the suspended particles and oil and other impurities through the rare earth disk. The effective volume becomes smaller, and with the circulation and disturbance of the water flow, sundries such as suspended solids flow into the water supply system, which seriously affects the water quality of the water ...
