Embodiment 1

[0046] This embodiment discloses a filter material for water purification and air deodorization, comprising the following components by weight ratio:

[0047] 20 liters of volcanic ash, 140 liters of natural debris pumice, 30 liters of Portland cement, and 16 liters of water.

[0048] This embodiment is used for the preparation method of the filter material of water purification and air deodorization, as figure 1 shown, including the following steps:

[0049] Step 1. Mix volcanic ash, natural pumice and cement according to the ratio, slowly add water and stir for 3 minutes to obtain the mixture; hold and visually confirm the mixing state, if adjustment is required, add water to make fine adjustments and finally prepare the mixed material. According to the above ratio and quantity of mixing materials, more than 10 pieces of semi-finished products can be produced. In mass production, raw materials are input according to this ratio.

[0050] Step 2. Put the mixture into the si...

Embodiment 2

[0058] This embodiment discloses a filter material for water purification and air deodorization, comprising the following components by weight ratio:

[0059] 10 liters of volcanic ash, 30 liters of pumice in the form of natural debris, 15 liters of Portland cement, and 10 liters of water.

[0060] This embodiment is used for the preparation method of the filter material of water purification and air deodorization, as figure 2 shown, including the following steps:

[0061] Step 1. Mix volcanic ash, natural pumice and cement according to the ratio, add water and stir to obtain a mixture;

Embodiment 3

[0070] This embodiment discloses a filter material for water purification and air deodorization, comprising the following components by weight ratio:

[0071] 10 liters of volcanic ash, 15 liters of pumice in the form of natural debris, 10 liters of Portland cement, and 16 liters of water.

[0072] This embodiment is used for the preparation method of the filter material of water purification and air deodorization, comprises the following steps:

[0073] Step 1. Mix volcanic ash, natural pumice and cement according to the ratio, add water and stir to obtain a mixture;

[0074] Step 2, put the well-mixed mixture into a granulator, extrude and granulate to form thin rod-shaped cylindrical particles, and the size of the thin rod-shaped cylindrical particles is 1 to 5 cm. In order to give full play to the function of the adhesive of cement, the formed plate is forced to ventilate at room temperature for a week, so that the internal moisture is volatilized.

Abstract

The invention provides a filtering material for water purification and air deodorization and a preparation method and application thereof, and the filtering material for water purification and air deodorization comprises the following components by weight: 8-12 parts of volcanic ash; 13 to 17 parts of natural pumice stone; and 8-12 parts of cement. The invention also discloses a preparation method of the filter material, which comprises the following steps: mixing the volcanic ash, the natural pumice stone and the cement according to the proportion, adding water and stirring to obtain a mixture; putting the mixture into a stock bin of a forming machine, pressurizing by the forming machine, vibrating, foaming through holes, solidifying and forming, air-drying at normal temperature, crushing, and then watering and curing the material to prepare the filtering material for water purification and air deodorization. The filtering material for water purification and air deodorization is high in adsorption capacity, has the capacity of adsorbing and capturing various pollutants, is long in service life and has the self-regeneration capacity.

Description

technical field [0001] The invention relates to filter material technology, in particular to a filter material for water purification and air deodorization, its preparation method and application. Background technique [0002] At present, solid adsorbents such as activated carbon are widely used to remove harmful substances and trace pollutants in water and air. These adsorbents have very strong selectivity for the adsorbed substances. Many substances with different chemical properties coexist in complex pollutants, and the adsorption and removal effect of these solid adsorbents is extremely limited. For example: the most commonly used activated carbon adsorbent has extremely weak adsorption capacity for alkaline substances such as ammonia and amines, and pigments containing dye particles. Sewage and air containing the above-mentioned substances pass through the activated carbon filter layer, and the content of pollutants does not change substantially before and after passi...
