Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, in particular to desulfurization wastewater treatment equipment. Background Art

[0002] Most of the power plants in my country use wet limestone desulfurization technology to remove SO2 from flue gas. The desulfurization wastewater generated during operation has complex components and many types of pollutants, making it one of the most difficult wastewaters to treat in coal-fired power plants. At present, the chemical precipitation method (commonly known as triple-box precipitation) is mainly used to treat desulfurization wastewater in China. The salt content of the treated water is very high, and it is easy to cause secondary pollution after direct discharge. Due to the small amount of desulfurization wastewater and high salt content, many scholars at home and abroad have begun to study the zero-emission treatment technology of desulfurization wastewater in recent years.

However, the stirring mechanism in the prior art only has a single simple stirring blade, which has poor stirring uniformity, is prone to water vortexes, has a slow mixing speed, and has poor effect.
