Embodiment Construction
[0033] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0034] Such as figure 1As shown, the present invention provides a reclaimed water reuse device for desulfurization treatment in a power plant, including an inclined tube settling unit 1 and a self-cleaning filter unit 2. The water outlet 11 in the middle of the unit is sequentially connected with the self-cleaning filter unit 2 and the activated carbon adsorption unit 6 activated carbon tank, and the activated carbon adsorption unit is preferably an activated carbon tank. The self-cleaning filter unit is provided with a pressure controller 3, and a first three-way control valve 4 is installed at the water outlet pipe of the booster pump 5. One port of the first three-way control valve is connected with the water inlet of the ultrafilter, and the first three-way control valve The other port of the valve is connected t...

Abstract
The invention discloses a water reuse device for desulfurization treatment in a power plant, which comprises a first-level treatment system, a second-level treatment system, and a third-level treatment system connected in sequence; the first-level treatment system includes an inclined tube settling unit, an activated carbon adsorption unit, an ultra- Filtration treatment unit; secondary treatment system includes anion exchange treatment unit and cation exchange treatment unit; tertiary treatment system includes medicament dosing unit, ultraviolet and photocatalytic treatment unit. The device can remove metal ions, fine particles and Cl in reclaimed water ‑ , F ‑ and other anions, and reused in the flue gas desulfurization treatment of power plants, avoiding the impact on the flue gas desulfurization treatment system, can save a lot of water resources, and realize the comprehensive utilization of resources, which has a strong social promotion and use value.
Description
technical field [0001] The invention relates to the technical field of water treatment, in particular to a water reuse device for desulfurization treatment in a power plant. Background technique [0002] With the rapid development of society and the increase of industrial production and residents' domestic water consumption, a large amount of wastewater is generated, which has a serious impact on the ecological environment. The generated wastewater must be treated to remove harmful substances and make it After reaching the corresponding national standards, discharge treatment will be carried out. [0003] my country is a country seriously short of water. It is currently in a stage of rapid development and is facing the problem of water shortage. The lack of water resources has gradually become an important factor restricting social and economic development, industrial production and even people's lives. The contradiction between supply and demand of water resources has becom...
