Problems solved by technology

[0004] At present, there are few studies on the remineralization of pure water. The mineralization filter products on the market mainly include the following categories: 1. Mix and granulate soluble calcium salt, magnesium salt, potassium salt, sodium salt and clay, The mineralized ball of this process is the main product on the market, but the dissolution in the early stage is not controlled, especially under soaking conditions, the degree of mineralization is too high, the proportion of various minerals is not coordinated, and there are potential safety hazards; 2. , zeolite, tourmaline and other rocks are ground and granulated. The products of this process have almost no effect under the condition of water, and there are safety risks such as heavy metal precipitation; 3. Directly fill with natural medical stone, etc. Processed natural rocks are too slow to precipitate minerals in water, so there is no effect in a short time, and there is also a safety risk of secondary pollution

preparation example Construction

[0025] The preparation method of the modified medical stone is as follows: crush the natural medical stone, activate it under a certain temperature condition, then use microwave to modify it, then use deionized water to ultrasonically wash it, then fully dry it in the air, and then cool it down. Grind thoroughly and sieve.

[0026] The preparation method of the modified zeolite is as follows: crush the natural zeolite, mix it with table salt and slaked lime, then add deionized water, air-dry it naturally, then heat it, take it out, add deionized water, heat it, add citric acid to adjust the pH after the liquid is reduced by half, Then soak, then ultrasonically wash with deionized water, then fully dry in the air, then cool, fully grind, and sieve to obtain.

[0027] The preparation method of the modified dolomite is: crushing the natural dolomite, using CaCl 2 and MgCl 2 The mixed solution is ultrasonically washed, then soaked, then fully dried in the air, then roasted in ca...

Embodiment 1

[0040] The natural medical stone is crushed, activated at 300°C for 3 hours, then modified with a microwave intensity of 80%, irradiated for 10 minutes, then washed with deionized water in an ultrasonic cleaner for 2 hours, and then heated in air at 120°C Fully dry, then cool, fully grind, and sieve 200 meshes to obtain modified medical stone. The natural medical stone is made of Tianshan Ordovician stratum; The mass ratio is mixed, then add deionized water, let it dry naturally, then put it in a muffle furnace and heat it at 480°C for 4 hours, take it out, add deionized water, heat it at 150°C, add citric acid after the liquid is reduced by half Adjust the pH to neutral, soak for 24 hours, then wash with deionized water in an ultrasonic cleaner for 2 hours, then fully dry in the air at 80°C, then cool, fully grind, and sieve through 200 mesh to obtain the modified zeolite. The natural zeolite is clinoptilolite from Siming Mountain, Zhejiang; the natural dolomite is crushed, w...

Embodiment 2

[0043] The modified medical stone 25g that makes by above-mentioned embodiment 1, modified zeolite 30g, modified dolomite 45g, modified wollastonite 20g, modified obsidian 20g, modified sea pumice 25g, modified quartz spot Rock 10g, coconut shell activated carbon 130g, modified sepiolite 50g, food-grade polyethylene 150g for batching, each 5g is a portion, after uniform mixing, put it into a hydraulic mold for sintering for 30 minutes, the hydraulic temperature is 150°C, and the pressure is 15MPa. After cooling, a 10-inch strontium mineralization filter element based on natural rock material is obtained.

Abstract

The invention provides a strontium mineralization filter element based on natural rock materials, which is made of the following raw materials in parts by mass: 5-20 parts of modified medical stone, 5-20 parts of modified zeolite, and 5-10 parts of modified dolomite , 2-5 parts of modified wollastonite, 2-5 parts of modified volcanic glass rock, 2-10 parts of modified sea pumice, 2-10 parts of modified quartz porphyry, 20-40 parts of activated carbon, modified sea foam 10-20 parts of strontium, 10-30 parts of binder, the strontium mineralization filter element can stably release macroelements and trace elements when filtering water, and remineralize low salinity water. The present invention also provides a preparation method of the strontium mineralization filter element, the steps are as follows: batching according to the mass parts of the raw materials; uniformly mixing the raw materials; putting the mixed raw materials into a hydraulic mold for sintering for 30 minutes, and the hydraulic temperature is 150 ℃, pressure 15Mpa, cooling, that is, the strontium mineralized filter element is produced. The strontium mineralization filter element provided by the invention has good mineralization effect and does not produce secondary pollution.

Description

technical field [0001] The invention relates to the technical field of preparation of pure water remineralization materials, in particular to a strontium mineralization filter element based on natural rock materials and a preparation method thereof. Background technique [0002] In recent years, the shortage of water resources and serious water pollution have become important factors affecting social and economic development and people's living standards. In order to solve the above problems, various water treatment technologies have developed rapidly. Desalination technologies such as reverse osmosis, electrodialysis, distillation, and ion exchange resins are rapidly applied in various industries, and are widely used in household water treatment equipment such as water purifiers, entering thousands of households. Existing desalination technology has been able to treat highly salinity salt water and various types of polluted sewage into pure water, which has greatly solved ...
