[0026] figure 1 A flowchart showing a method for preparing a modified zeolite adsorption material for water purification equipment according to a method embodiment of the present invention includes the following steps:

[0027] Step S102, zeolite pretreatment: pulverize the zeolite ore, screen it with an 18-mesh sieve, select zeolite with a specific particle size range, remove the powder with fine particle size and large particle size zeolite, then rinse it with pure water, air dry it naturally or place it in the heating and drying in an oven to obtain the first pretreated zeolite, and placing it in a drying device for subsequent use;

[0028] Step S104, primary modification of zeolite: prepare sodium chloride solution with pure water, then soak the first pretreated zeolite in the sodium chloride solution, heat and stir, take out the first pretreated zeolite after completion, and rinse with pure water clean, then put it into an oven for heating and drying to obtain the second...

Embodiment 1

[0045] 1. Zeolite pretreatment:

[0046] The zeolite ore is crushed, screened with an 18-mesh screen, and the zeolite with a particle size of 1-20 mm is selected, and the fine powder and large-grained zeolite are removed. Then rinse it with pure water, place it in a desiccator to dry naturally for 26 hours, and set it aside.

[0047] 2. Primary modification of zeolite:

[0048] Prepare 4.6mg / L sodium chloride solution with purified water. Then soak the zeolite in sodium chloride solution and heat to 95°C while stirring for 120 minutes. When finished, take it out and rinse it with pure water.

[0049] Then put it into an oven and heat it to 100° C. and dry it for 15 minutes, and place it in a drying appliance for later use.

[0050] 3. Titanium dioxide modified zeolite:

[0051] Place the preliminarily modified zeolite in the nano-titanium dioxide solution for soaking, then take it out and spin dry. Use a wire mesh screen to place in an oven heated to 100 and dry for 10 min...

Embodiment 2

[0054] 1. Zeolite pretreatment:

[0055] The zeolite ore is crushed, screened with an 18-mesh screen, and the zeolite with a particle size of 1-20 mm is selected, and the fine powder and large-grained zeolite are removed. Rinse it with pure water, place it in an oven and heat it to 50°C for 10 minutes, take it out and place it in a dry ceramic jar for later use.

[0056] 2. Primary modification of zeolite:

[0057] Prepare 5mg / L sodium chloride solution with purified water. Then soak the zeolite in sodium chloride solution and heat to 98°C while stirring for 120 minutes. When finished, take it out and rinse it with pure water.

[0058] Then put it into an oven and heat it to 100°C to dry for 10 minutes, and place it in a drying appliance for later use.

[0059] 3. Titanium dioxide modified zeolite:

[0060] Place the preliminarily modified zeolite in the nano-titanium dioxide solution for soaking, then take it out and spin dry. Use a wire mesh screen to place in an oven ...

Abstract

The invention belongs to the technical field of new environment-friendly materials for sewage treatment, and particularly relates to a preparation method of a modified zeolite adsorption material for water purification equipment. The preparation method of the modified zeolite adsorption material for water purification equipment includes the first step of pretreating zeolite, the second step of modifying zeolite primarily, and the third step of modifying zeolite with titanium dioxide. By means of the preparation method of the modified zeolite adsorption material for water purification equipment, the modified zeolite adsorption material stable in performance can be prepared, the preparation process is simple, and production and processing are convenient. The adsorption material is mainly used for water purifiers and other water treatment products for preparing domestic drinking water so as to improve the purification quality of drinking water, prolong the service life, increase the yield of pure water and lower production cost.

Description

technical field [0001] The invention belongs to the technical field of environmentally friendly new materials for sewage treatment, and in particular relates to a preparation method of a modified zeolite adsorption material used in water purification equipment. Background technique [0002] According to an article published by Science in 2013, it is estimated that more than 100 million people in the world still drink high-arsenic groundwater. In my country, 19.6 million people are affected by high-arsenic groundwater, and the water quality of millions of underground wells needs to be treated urgently. [0003] At present, the methods for treating arsenic-containing wastewater at home and abroad mainly include precipitation method, ion exchange method, biological method, membrane method, electrocoagulation method, adsorption method and so on. These methods have their own characteristics and have their advantages and disadvantages. For example, the arsenic removal technology ...
