See how zeolites treat wastewater waste gas Environmental issues are one of the most important issues facing humanity in the world today, and have been highly valued by countries around the world. With the rapid development of China's social economy, environmental issues have become increasingly prominent. Environmental protection and governance, many countries in the world, especially the developed countries for non-gold minerals applications in environmental protection very seriously genus. Among them, non-metallic minerals - zeolites are favored. Zeolites are a family of aqueous, having a communication channel, as a shelf-like configuration of alkali or alkaline earth metal silicate or aluminosilicate mineral, first discovered in 1756 by the Swedish mineralogist Cronstedt, its boiling foaming occurs upon heating The phenomenon is named "zeolite". China's zeolite resources are very rich. Since the discovery of the Jinyun zeolite deposit in 1972, more than 400 deposits have been discovered in 22 provinces, municipalities and autonomous regions across the country, controlling the prospective reserves of about 3 billion tons, ranking the world's forefront. Zeolite has a unique internal structure and crystallization chemistry, and has adsorptivity, ion exchange, catalytic and acid and heat resistance. In addition, it also has process properties such as chemical reactivity, far-infrared radiation, and reversible dehydration. At present, the zeolite has been widely used in agriculture, petrochemicals, building materials, ceramics, metallurgy, medicine, catalyst, detergent additives, environmental management, household chemicals and other fields. Among them, with the prominent environmental pollution problems, and the selectivity, adjustability and safety of zeolite, the application of zeolite in environmental management is more and more extensive. I. Application of zeolite in treating wastewater Zeolites have a special tetrahedral structure and thus have a large surface area and high ion exchange and adsorption capacity, making zeolite widely used in wastewater treatment. Zeolite can remove organic pollutants from wastewater, remove ammonia nitrogen, remove suspended solids, algae, etc., and reduce turbidity of effluent. It also removes heavy metal ions from the water. The foreign patent (J52034549) introduces the modification of the oblique hair and mordenite into Na type and NH3 type zeolite, and uses it to act as an "ion sieve" for certain ions in the solution to treat non-ferrous metal mines, smelters and chemical plants. The wastewater containing heavy metal ions is discharged, and then the metal is recovered by desorption. In addition to treating wastewater, zeolites can also modify water quality. For example, Xisha Islands drinking water is treated with local volcanic breccia containing zeolite, which removes organic matter from seawater, reduces salinity, reduces ammonia ions and nitrate, and becomes standard drinking water. 2. Application of zeolite in the treatment of waste gas Hydrocarbons, sulfur, nitrogen, nitrogen, carbon monoxide, and hydrogen sulfide emitted from the chemical, light industry, paint, and transportation industries are the main harmful gases that pollute the atmosphere. Zeolite has good adsorption and purification functions for these gases, especially in the low temperature range, which has the adsorption capacity not possessed by other adsorbents. For example, in the natural gas production process, the selective adsorption of zeolite is used to separate harmful impurities such as H2O, CO2, and SO2 in natural gas, thereby improving the purity of natural gas and reducing pollution during combustion. People also use zeolite to recover ammonia from the exhaust gas of synthetic ammonia. Removal of H2S from the exhaust gas of the sulfuric acid plant; for the purification of hydrogen in the chlor-alkali industry, the mercury in the hydrogen can be removed to below 0.1 ppm. In addition, natural zeolite has a strong ability to resist nuclear fission radiation, prevent nuclear waste leakage, and control radioactive contamination. As an environmental material, zeolite can also be used as a washing aid for STPP, as a paper filler, antibacterial material, feed additive, deodorant, filter, preservative, suspending agent, and the like. summary The famous mineralogist Mupton once pointed out that due to global environmental regulation and environmental protection needs, humans entered the "zeolite century" in the 1970s. Zeolite has a wide range of application prospects in environmental management due to its excellent environmental purification, repair and replacement functions, as well as its advantages of low cost, easy preparation, and no secondary pollution. We should give full play to the resource advantages of zeolite in China, strengthen the research on zeolite, and develop new zeolite materials with higher added value, so as to produce better social, economic and ecological effects.
