Organic halides are often used as raw materials, intermediates, solvents and the like to be widely applied to organic synthesis, and have obvious effects in human production and life. The use and discharge of a large amount of halogenated organic matters cause the pollution of the halogenated matters in the water body to be increasingly serious, and threaten the ecological safety and the human health. Such as halogenated hydrocarbons, polychlorinated biphenyls, organochlorine pesticides, antibiotics and perfluorooctanesulfonic acid pollutants are representative of the persistent organic pollutants that are widely present in water. A large number of researches show that the halogenated organic pollutants have the characteristics of environmental persistence, difficult biodegradation, bioaccumulation, high toxicity, long-distance migration capability and the like, are distributed in the field environments such as soil, atmosphere and the like, and how to distribute the halogenated organic pollutantsEffective solutions to halogenated pollutants have become a focus of attention in the environmental field. The common halogenated organic matter treatment methods include adsorption method, incineration method, wet catalytic oxidation method, chemical reduction method of loading noble metal with hydrogen storage capacity, advanced oxidation and advanced reduction method, wherein the advanced reduction method can generate highly reductive hydrated electrons in the systeme aq -And hydrogen free radical H breaks C-X bond to have strong dehalogenation effect, thereby breaking the structure of the halide and improving biodegradability. The invention adopts ultraviolet light to activate wet magnesium method flue gas desulfurization waste to form a high-grade reduction system, and removes halide in wastewater.
The wet magnesium method flue gas desulfurization technique is similar to the traditional wet lime-gypsum method in basic principle, and takes magnesium oxide slurry as an absorbent to be fully contacted with the flue gas in an absorption tower SO as to remove SO in the flue gas2Absorbed and fixed in the form of sulfite. The desulfurization waste mainly comprises magnesium sulfite, a small amount of magnesium sulfate, magnesium carbonate and unreacted desulfurizer magnesium hydroxide. The waste treatment method mainly comprises a abandoning method, a method for recovering magnesium sulfate by forced oxidation and a method for regenerating magnesium oxide by pyrolysis. However, the above processes are relatively expensive in both capital and operating costs, and the cost of desulfurization can only be significantly reduced if the recovered product can be sold. Therefore, it is very important to find a low-cost desulfurization waste treatment method or resource utilization method.
