Composite water purification material preparation method

Abstract

The invention provides a composite water purification material preparation method. The steps are as follows: (1) KDF, limonite, tourmaline and mesoporous composite molecular sieve are mixed accordingto a certain proportion, added with water and stirred for 20 to 30 minutes; (2) the mixed material is homogenized for 30 to 40 minutes, added with clay and uniformly stirred again; (3) the material obtained in step 2 is dewatered to be concentrated and produced into spherical raw material balls; (4) the spherical raw material balls are sintered under high temperature, and thereby the composite water purification material disclosed by the invention is prepared. The composite water purification material disclosed by the invention can effectively remove harmful elements and impurities in water, can release a variety of trace elements benefiting the human body, and can also effectively inhibit the breeding of bacteria.

Description

technical field

[0001] The invention relates to the technical field of water purification, in particular to a method for preparing a composite water purification material. Background technique

[0002] With the increase of population and the development of industry and economy, the pollution of surface water system is becoming more and more serious. Factory sewage and domestic sewage make the national high-quality water source decrease continuously; groundwater pollution is even more shocking. Landfill, septic tank, mine pollution, factory pollution Underground sewage discharge makes nearly 60% of the country's groundwater quality "poor". At present, my country's waterworks still use traditional treatment processes, which cannot effectively remove most of the pollutants. More than 2,100 organic and inorganic pollutants have been detected in the water.

[0003] For different types of pollutants, a variety of water purification materials have been developed and used in water ...
