Hydrochloric acid in the production process of the main pollutants in the steps of: a surface oxidation pickling: regularly produce waste hydrochloric acid, hydrochloric acid content higher industrial manufacturers, but contains a lot of iron oxides and iron ions, such waste will collected and treated separately. b surface water acidification: After acidification, have to use a lot of water for rinsing hydrochloric acid plant processed products, so a large amount of rinsing water, and products in the plating process the surface will take a small amount of plating solution and phosphoric acid solution and produce a large amount of washing water. The main pollutants in wastewater Zn, Cu and a small amount of phosphate, in addition to absorbing the acid mist emissions from waste water installations. c Other sporadic waste: Kandal subsequent processing, it will regularly produce a certain amount of waste degreasing solution. Waste acid and waste degreasing solution can be achieved simultaneously. Hydrochloric acid in organic synthesis field: for example, hydrochloric acid factory in Nantong, at a temperature of 180 ℃ ~ 200 ℃ and mercury salts (such as HgCl2) as catalyst under the conditions of hydrogen chloride and acetylene addition reaction of vinyl chloride, and then the initiator under the action of hydrochloric acid plant in Sichuan, polymerized polyvinyl chloride. Dyeing industry, for example, pickling cotton bleached, mercerized cotton treated residual alkali neutralization, should be treated with hydrochloric acid. In the printing process, some dye insoluble in water, treated with hydrochloric acid required to make a soluble hydrochloride, to apply.
