Embodiment Construction

[0012] 1. Ingredients:

[0013] In 100 kg of diatomite materials, 10 kg of bentonite is mixed as a raw material.

[0014] 2. Mud making:

[0015] Add 40 kg of water to 110 kg of raw material, mix and stir to make the raw material have proper humidity and become diatomite mud.

[0016] 3. Granulation:

[0017] Add the diatomite mud into the screw extruder, the screw extruder has a round hole mouth, and the mud strip is extruded through the mouth. granules, put the mud granules into the material tray with diatomite and shake it, so that the mud granules are wrapped with mud powder, and the mud powder absorbs the moisture on the surface of the mud granules, so that the mud granules have strength, and then the powdery diatomaceous earth is screened out , the remaining diatomite mud particles.

[0018] 4. Drying of mud particles:

[0019] The mud grains are dried or dried to become dry mud grains.

[0020] 5. Mud roasting:

[0021] Add the dry clay particles into the sinteri...

Abstract

The invention provides a method for producing water-purification ceramic particles by using kieselguhr. The method comprises the processes of mixing, producing mud, producing particles, drying mud particles and roasting the mud particles. The ceramic particles produced by the method are transparent in texture and has the adsorbability; meanwhile, adhesion and propagation of water-purification microorganisms are facilitated; the ceramic particles also has the filtration performance. The method is suitable for production of the water-purification ceramic particles.

Description

technical field [0001] The invention provides a diatomite water purification ceramsite production method in the field of environmental protection. Background technique [0002] In the field of water purification, adsorbents are often used to purify substances, impurities and chemical pollutants in water. When diatomite or bentonite is used, since diatomite or bentonite is powdery, it is not easy to remove pollutants in water, and the suspension The material is not easy to settle, and at the same time, it cannot produce biological purification. Therefore, how to select and prepare ceramsite for water purification is the development direction. [0003] Because the existing ceramsite has no permeability, the surface is smooth, harmful substances cannot be adsorbed, and it is also not conducive to the attachment and reproduction of water purification microorganisms. Therefore, it cannot be used as a water purification agent. Contents of the invention [0004] In order to re...
