1. Caustic soda for sewage treatment and sodium hydroxide for industrial wastewater treatment. Since caustic soda mainly contains hydroxide and sodium ions+, hydroxide can combine with many kinds of metal ions to form flocs or precipitates, such as in sewage. Contains aluminum ions + or iron ions +, + and other metal ions, strong acid and weak acid salts, etc., reacts with ions in caustic soda to produce floc or insoluble matter precipitation + +, + + The main content of aluminum chloride is three The flocculation principle of aluminum oxide is mainly to combine with hydroxide radicals in sewage to form flocculent substances to achieve the flocculation effect. Caustic soda and sodium hydroxide can also remove excess acid ions in industrial sewage, such as, etc. Caustic soda is also often used to adjust the value, and the dosage of sodium hydroxide is determined according to the situation. Sodium dihydroxide desiccant sodium hydroxide and caustic soda are strong bases and have alkaline properties, so they can dry alkaline gases and neutral gases. For example, alkaline gas {ammonia | neutral gas {nitrogen {oxygen {hydrogen {methane} {carbon monoxide) and inert gases can react with acidic gases, so acidic gases cannot be dried. Such as acid gas {carbon dioxide {{hydrogen sulfide {{sulfur dioxide] and other flake sodium hydroxide flakes are widely used in papermaking, synthetic washing and soap, viscose fiber, rayon and cotton fabrics and other light textile industries, pesticides, dyes, rubber and chemical industries, petroleum The petroleum industry drills, refines petroleum oils and refines tar. Caustic soda is used in refining petroleum, papermaking, textiles, printing and dyeing, improving soil with lime, manufacturing soap, metallurgical industry, and converting active ingredients in ores into soluble sodium salts. In the chemical industry, caustic soda is used in medium and electrolyzed water. Making aluminum hydroxide and making ceramics.
