Description

Technical Field

[0002] As we all know, coal-fired power plants, refineries, chemical plants, etc. emit a large amount of sulfur-containing flue gas. The sulfur dioxide SO2 in these flue gases needs to be removed by the flue gas desulfurization FGD system to reduce the formation of acid rain and air pollution; however, the desulfurization process often generates wastewater containing heavy metals, suspended matter, fluorides, chlorides and other pollutants. If these wastewaters are discharged directly without treatment, they will cause serious pollution to the water body, so these wastewaters also need to be purified by treatment equipment before they can be discharged to the outside.

[0003] When the existing flue gas desulfurization wastewater treatment equipment is in use, in order to prevent the fixed particles and impurities mixed in the wastewater from affecting the working effect of the wastewater treatment, it is often filtered through a filtering device in advance, and then the filtering is completed before entering the treatment equipment for purification treatment, and finally discharged; but when the existing flue gas desulfurization wastewater treatment equipment is in use, it is found that the connection method of the filtering device in the flue gas desulfurization wastewater treatment equipment is relatively cumbersome.
