Embodiment 1

[0034] A specific embodiment of a filler capable of generating free radicals according to the present invention, the described filler capable of generating free radicals is composed of a photocatalyst and a radioactive ore, the shape of the radioactive ore is spherical particles, and the radioactive ore is radium stone.

[0035] The spherical particles of the radioactive ore have a diameter of 6mm.

[0036] Of course, in different embodiments, the above-mentioned diameters can be adjusted to some extent.

[0037] The radioactivity requirements of the radioactive ore are: the dose rate at a distance of 1 meter from 20 kg of radioactive ore particles is not higher than 2.5 μsV / h; the weight ratio of the photocatalyst to the radioactive ore particles is 3:2.

[0038] The filler capable of generating free radicals also includes a binder, the photocatalyst and the binder form an outer coating structure, and the photocatalyst and the binder are powders.

[0039] The photocatalyst ...

Embodiment 2

[0047] The principle of embodiment 2 is the same as that of embodiment 1, the difference is:

[0048] A filler capable of generating free radicals in the present invention is composed of a photocatalyst and radioactive ore, the shape of the radioactive ore is spherical particles, and the radioactive ore is thorite. The diameter of the spherical particles of the thorite is 2 mm.

[0049] The preparation method of the filler capable of generating free radicals of the present invention may further comprise the steps:

[0050] In step (2), 30 kg of spherical thorite particles with a diameter of 2 mm were weighed for use as a spare.

[0051] In step (3), add 3 times the weight of water to the above-mentioned outer coating part and stir evenly to form a slurry, and put it into a disc granulator together with the above-mentioned spherical radium stone particles for uniform contact.

Embodiment 3

[0053] The principle of embodiment 3 is the same as that of embodiment 1, the difference is:

[0054] A filler capable of generating free radicals of the present invention is composed of a photocatalyst and a radioactive ore, the shape of the radioactive ore is spherical particles, and the radioactive ore is radium stone. The diameter of the spherical particles of the radium stone is 10mm.

[0055] The preparation method of the filler capable of generating free radicals of the present invention may further comprise the steps:

[0056] In step (2), 30 kg of spherical radium stone particles with a diameter of 10 mm are weighed for use as a spare.

[0057]In step (3), add 2.5 times the weight of water to the outer coating part and stir evenly to form a slurry, and put it into a disc granulator together with the spherical radium stone particles for uniform contact.

Abstract

The invention discloses a filler capable of generating free radicals. The filler capable of generating free radicals is composed of a photocatalyst and radioactive ore; the radioactive ore has a shapeof spherical or columnar particles; the radioactive ore is radium or thorium ore; the diameter of the spherical particle of the radioactive ore is 2-10mm; the diameter of the columnar particle of theradioactive ore is 3-6mm; the height of the columnar particle of the radioactive ore is 6-12mm. The filler capable of generating free radicals has the advantages of high sewage treatment efficiency,low energy consumption, no maintenance, high efficiency of free radical generation and low requirement on raw materials.

Description

technical field [0001] The invention relates to the technical field of fillers, in particular to a filler capable of generating free radicals and a preparation method thereof. Background technique [0002] The purpose of sewage treatment is to remove organic matter, ammonia nitrogen and other pollutants in wastewater through various physical and chemical means. However, in some cases, it is difficult or too late to treat pollutants in wastewater with biological treatment as the core of the existing technical means, especially for pollutants composed of compounds that do not exist in nature. The above situation is particularly evident in special wastewater such as printing and dyeing wastewater, pharmaceutical wastewater, papermaking wastewater, food processing wastewater, and wastewater with high concentration of organic matter. [0003] For the wastewater treatment of the above situation, the chemical oxidation method is often used to remove the pollutants in the water bod...
