Natural zeolite is a kind of shelf silicate mineral, which is very widely distributed in the earth's crust. At present, zeolite deposits have been found in more than 40 countries in the world, including the United States, Japan and Russia, and the total number of deposits reaches more than 1,000, and more than 40 kinds of zeolites have been found.

Deep nitrogen and phosphorus removal from wastewater is an important measure for the reuse of municipal wastewater resources and water pollution control.

Zeolite is a water-reticulated aluminosilicate of alkali and alkaline earth metals, a generic term for the zeolite family of minerals, first discovered in Europe in 1756. The mineralogist Kronsti in Sweden found a class of natural silica-aluminate ores that would boil when burned, hence the name "ze

Natural zeolite is an emerging material that is widely used in industry, agriculture and defense, and its uses are still being developed. Zeolites are used as ion exchangers, adsorbent separators, desiccants, catalysts, and cement blending materials.

Greenhouse cultivation as a major industry in modern rural areas, greenhouse soil degradation problems also seriously plague local farmers growing vegetables. Vegetable production in many areas of China over the years has caused soil tightening phenomena, some of which have become salinized, and vegetable yields have been declining year by year.

Natural zeolite is a silica-alumina material with skeletal structure, which is usually used as an auxiliary cementing material for cement and concrete. 2018, the Ministry of Housing and Urban-Rural Development published the industry standard "Natural zeolite powder for cement and mortar", which stipulates that zeolite material should be used as a component of concrete.
