Hydrochloric acid in the production process of the main pollutants in the steps of: a surface oxidation pickling: regularly produce waste hydrochloric acid, a high acid content, and contains a lot of iron oxides and iron ions, such waste will be collected and treated separately . b surface water acidification: After hydrochloric acid treatment of industrial manufacturers, have to use a lot of water rinse for processed products plant in Sichuan hydrochloric acid, it produces a large amount of rinsing water hydrochloric acid plant, while products in the electroplating process which will take a small amount of surface plating liquid and phosphoric acid liquid and produce large amounts of clean 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 of concentrated hydrochloric acid manufacturers, will regularly produce a certain amount of waste degreasing solution. Waste acid and waste degreasing solution can be achieved simultaneously. Food Industry China's "food additives health standards" (GB2760-2014) provides: usage of normal production needs. Hydrochloric acid hydrolysis of starch for the manufacture of starch syrup. System of law: refined starch and starch water becomes milk, add hydrochloric acid to make it a pH value of 1.9 to 2.1 acid starch milk, heated to boiling starch hydrolysis, complete with 5% sodium carbonate and, after filtration, bleaching, concentrated to afford starch syrup. In the manufacture of canned citrus, hydrochloric acid for the removal of orange bag clothing. Method: The peeled orange petals into a concentration of 0.1% hydrochloric acid at 30 ~ 35 ℃ in place 20min, until pectin hydrolysis to remove the water rinse, and then 0.8% sodium hydroxide solution in 35 to 40 rinse under ℃ about 20min, removed the coat and then rinsed with water to remove residue and lye. In addition, hydrochloric acid is also used as a pH adjusting agent and a starch modifier, etc., are not allowed in food residues, food eventually have to remove or neutralize [6] made before. For example, when the system chemical soy sauce, the cooked bean dip and other raw materials) soaked in a solution containing a certain amount of hydrochloric acid, maintaining a certain temperature, hydrochloric acid with a catalytic complex protein which can promote the hydrolysis, after a certain time, it amino acids having umami generated, then caustic soda (or soda) and, that was sodium amino acids.
