Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization water tanks, in particular to a circulating water tank for desulfurization. Background Art

[0002] Desulfurization wastewater treatment is necessary, because wastewater containing sulfide is harmful to the environment and human health, and will cause problems such as water acidification and plant death, and will seriously pollute the soil. Therefore, it is necessary to desulfurize the corresponding sewage. When desulfurizing the wastewater, some necessary substances need to be added, such as lime milk or sodium hydroxide and flocculants, etc., to promote the coagulation of fine suspended matter and colloidal substances into large particles for sedimentation. However, the addition of lime milk or sodium hydroxide and flocculants cannot fully contact the sewage. At the same time, after the necessary substances are added to the sewage, it enters the sedimentation tank for sedimentation. If the sedimentation tank is continuously discharged for sedimentation, the suspended matter in the sewage will be in a state of constant floating, and it cannot be well precipitated. Therefore, in order to solve the above problems, we proposed a circulating water pool for desulfurization to solve the above problems. Utility Model Content
