The sodium sulfite for the treatment of fluid, sulfate and thiosulfate

摘要

In the lye that the flue gas desulfurization of processing method si i itanu concentrated solutions, sulfuric acid and thiosulfuric acid soda lye or product originated in generates, the pH value of cooling water is increased less than 1, contain hydrochloric acid, work of the p edp í rac í washing machines from means of flue gas desulfurization of power plant device lime stone and coal, caco.sub.3.n.CaO in p á lenym or lime lye is still extra acid, sulfur dioxide, so. with the product of oneselfsub.2.n.Reaction after merging, si i itanu sodium and sodium thiosulfate and absorption by Hydrochloric Acid act on the lime stone gypsum of transfer or quick lime in hydrochloric acid and sodium sulphate, and the effect of extra chilled water unit is by i ic í m en é ho lime Ca(OH)sub.2.n., sodium chloride and performer, caso.sub.4.n..2h.sub.2.n.Contain gypsum from i ic í ho, sludge incineration device is transferred to ancillary equipment p desulfurization from the topeni ti sludge of burning in power plant and sulphur
