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 ...

Problems solved by technology

However, the existing materials all have problems such as narrow processing range, high cost, or risk of secondary pollution: for example, PP cotton is only for the removal of large particles such as suspended solids, sediment, rust, and colloids in water, and for bacteria, organic molecules, etc. None can do anything; commonly used activated carbon can remove residual chlorine, pesticide residues, pigments, etc., but cannot effectively adsorb bacteria, calcium and magnesium ions, etc.; RO (reverse osmosis) membrane can remove most of the metal ions, but it also removes the harmful substances that are beneficial to the human body. minerals, and the cost is high; KDF can effectively treat residual chlorine and heavy metals in water, and inhibit the growth of microorganisms in water, but there is still the problem of secondary pollution by heavy metals

Water purification is mostly achieved through the filter element, and the transition life of the filter element is limited. After a period of use, the filter element fails and must be replaced in time. Otherwise, the invalid filter element will not only not purify the water flow, but will also aggravate the pollution of the water flow. Therefore, providing a It is particularly important to develop a water purification material that can effectively remove harmful elements and impurities in water.
