Problems solved by technology
[0006] The first object of the present invention is to provide a treatment system for desulfurization wastewater. The treatment system utilizes the high-temperature flue gas produced in the factory area and the desulfurization wastewater in the power wave scrubber to achieve the purpose of concentration by circulating heat and mass transfer exchanges. The treatment system has the advantages of short treatment process, low equipment cost, recovery of flue gas heat to reduce operating costs, and no wastewater scaling, etc., which solves the problems of long process flow, difficult operation, and very high investment and operating costs in the existing technology

The invention provides a desulfurization wastewater treatment system and method. The system comprises a high-temperature flue gas pipeline, a power wave washing machine and a washing tower, wherein aoutlet of the high-temperature flue gas pipeline is communicated with a gas phase inlet of the power wave washing machine, and a gas phase outlet of the power wave washing machine is communicated witha gas inlet of the washing tower; a sewage outlet of the power wave washing machine is communicated with the high-temperature flue gas pipeline through a circulating pump, and a desulfurization wastewater inlet is formed in the power wave washing machine as a liquid phase inlet. The treatment system uses the circulating heat and mass transfer exchange between high temperature flue gas and desulfurization wastewater produced by a factory in the power wave washing machine to realize the concentration. The treatment system has the advantages of short treatment process, low equipment cost, recovery of flue gas heat to reduce the operation cost, no wastewater scaling and the like, and solves the problems of long process flow, large operation difficulty and very high investment and operation cost in the prior art.
Description
technical field [0001] The invention relates to the field of wastewater treatment, in particular to a treatment system and method for desulfurization wastewater. Background technique [0002] "Limestone-gypsum" wet desulfurization wastewater is the difficulty of zero discharge of power plant wastewater, and zero discharge of power plant wastewater mainly refers to zero discharge of desulfurization wastewater. The total salt content, chloride ion, hardness, suspended solids, and heavy metal content of wet desulfurization wastewater are very high, and the reuse methods are very limited, and the treatment is also very difficult. Wet desulfurization wastewater treatment has become the focus of power plants. [0003] However, at present, there are many schools of zero-discharge technologies for desulfurization wastewater, and most of the technologies are in the pilot and technical verification stages. Solving the problems of fouling, high energy consumption, and high costs in wa...
