Zeolite For Sewage Treatment

A. Zeolite to have a strong ammonia adsorption , and by hydrochloric acid pretreatment , industrial salt activation, After the baking process , such as zeolites can be modified to remove traces of ammonia in water,Not up to standard so that the water meet the state drinking water standards . And through different processes of the modified zeolite can also remove the fluoride and arsenic in water, treated water quality can be achieved after the national drinking water standards and high-fluorine water issues in China provide a new way .In addition, the adjustment of the ratio of zeolite in Alumina , but also to remove residual chlorine in tap water , Meng and iron, and excess of heavy metals.

B. after the two urban sewage treatment , some still can not meet the state sewage discharge requirements. In such circumstances , could be secondary treatment of sewage through the modification of zeolite filter, filter through their role, can effectively reduce nitrogen and phosphorus, heavy metals and other content. For example, some enterprises discharge waste water after plating two sewage treatment, water weight of the heavy metal content still can not meet emissions standards, you can use the modified zeolite treatment , ion exchange through the role of pollutants will be removed to achieve emis--sions standards.

C. the activity of activated carbon and zeolite can be used in combination, make up for zeolite to remove the ability of low organic matter defects, removing the water through activated carbon remnants of fluorine, arsenic, manganese, soluble salts and other substances. Give full play to the role of the two adsorption, and zeolite functional ion exchange, removal of sewage in the organic and inorganic molecular ion.
