Embodiment 1

[0045] According to the mixing mass ratio of 30% and 70%, appropriate amount of porous volcanic particles with an average particle size of 0.6 mm and manganese sand with an average particle size of 2 mm were weighed respectively. Wherein, the compressive strength of the volcanic rock particles is not less than 5.5Mpa, the shear strength is not less than 3.5Mpa, the porosity is not less than 75%, and the specific gravity is 1.4g / cm 3 , bulk density 0.7g / cm 3 .

[0046] Then the two materials were mixed and compacted naturally to obtain the mixed filter material of Example 1.

Embodiment 2

[0048] According to the mixing mass ratio of 10% and 90%, appropriate amount of porous volcanic particles with an average particle size of 2.6 mm and manganese sand with an average particle size of 2 mm were weighed respectively. Wherein, the compressive strength of the volcanic rock particles is not less than 5.5Mpa, the shear strength is not less than 3.5Mpa, the porosity is not less than 75%, and the specific gravity is 1.1g / cm 3 , bulk density 0.6g / cm 3 .

[0049] Then the two materials were mixed and compacted naturally to obtain the mixed filter material of Example 2.

Embodiment 3

[0051] According to the mixing mass ratio of 70% and 30%, appropriate amount of porous volcanic particles with an average particle size of 3 mm and manganese sand with an average particle size of 2 mm were weighed respectively. Wherein, the compressive strength of the volcanic rock particles is not less than 5.5Mpa, the shear strength is not less than 3.5Mpa, the porosity is not less than 75%, and the specific gravity is 1.3g / cm 3 , bulk density 0.6 / cm 3 .

[0052] Then the two materials were mixed and compacted naturally to obtain the mixed filter material of Example 3.

Abstract

The invention provides a multifunctional compound filter material. In the compound filter material, a filtering material and a function material are mixed, so that the prepared compound filter material has the advantages of simultaneously filtering and removing multiple pollutants and the like. In addition, the invention further provides a preparation method of the compound filter material. In the method, the compound filter material is prepared by mixing the filtering material and the function material, so that the preparation method has the advantages of being simple, convenient and the like. The invention further provides a filtering device. In the device, filtration is performed by using the compound filter material, accordingly multiple purifying functions can be achieved in the same device, and the occupied area of the device can be decreased. The invention also provides a filtering method. In the method, multiple pollutants can be simultaneously removed in one-time filtering by using the filtering material or the filtering device, and the filtering efficiency is improved.

Description

technical field [0001] The invention relates to the field of water filtration, in particular to a multifunctional composite filter material, a preparation method, a filter device and a filter method. Background technique [0002] my country is seriously short of water resources. It belongs to a water-scarce country, and the contradiction between supply and demand of water resources is very prominent. However, due to the uneven distribution of water resources, water pollution is also serious, and due to the spread of air pollution and the use of pesticides, the water quality is declining year by year, making it unsuitable for production or daily use. Effective purification of water to reduce impurities in water, so that water can be recycled, has become the focus of current research. [0003] Traditional water treatment filter materials can be divided into two categories, one is materials with the function of filtering suspended solids, such as quartz sand, etc.; the other i...
