Description
Technical field
The present invention relates to a kind of filter core, particularly relate to a kind of filter core with molecular sieve structure and preparation method thereof.
Background technology
At present, along with developing rapidly of industry and agricultural, cause China's water resource to be seriously damaged.Increasing industrial wastewater discharge has destroyed our ecological environment in rivers, lake.The discharging wantonly of the extensive application of agricultural chemicals, pesticide and house refuse causes the quality of groundwater variation, and causes producing in the water a lot of harmful materials.Water pollutes more and more becomes the severe problem that influences people's life.
Present stage, along with growth in the living standard, people's health care consciousness is also more and more stronger.Only can not satisfy people through the water source of waterworks sterilization normally drinks and other service condition.Drink the water quality of health, safety, become most of residents' primary demand.The water-purifying device miscellaneous and the filtering technique that occur on the market arise at the historic moment under this condition.
At present, the material for core that is used for purifying drinking water mainly contains PP cotton, active carbon, ion exchange resin, RO reverse osmosis membrane etc.The PP cotton is used for absorption more and removes suspended impurity, particle, mud or the like in the water, is applicable to preposition filtration.Active carbon is an abutment surface cellular tissue absorption chemical pollutant, can improve the heterochromatic peculiar smell in the water and remove some organic pollutions, but effect is not fine, and some heavy metals and salts substances in the water are not had tangible removal effect, is not suitable for being used in the relatively poor area of water quality.Ion exchange resin generally is used for calcium, magnesium ion softening or removal water, and the reduction hardness of water is used for industrial preparation demineralized water more or family's soft water needs, and is not suitable for human body and directly drinks.The RO counter-infiltration is one of effective water treatment mode in the existing science and technology, it can handle salt in the water (as hardness impurity such as calcium, magnesium), heavy metal, chemical residual material effectively, but the water that this filter membrane comes out is pure water, be used for industrial pure water needs such as seawater desalination system, electric ultrapure water rectification systems, biochemical pharmacy more, wash kidney, Cosmetic Manufacture manufacturing, beverage, packing water etc., this water does not contain human body and needs mineral matter, thereby is not suitable for human body and directly drinks.
Summary of the invention
The present invention provides a kind of filter core that is used for purifying drinking water in order to address the above problem, especially a kind of filter core with molecular sieve structure made from molecular screen material.This filter core with molecular sieve structure can effectively improve the water quality of drinking water, goes out water security, health, meets national drinking water standard fully, is fit to very much the demand of drinking.
