Embodiment 1

[0043]1. Preparation of mineral composite materials

[0044] Collect granite, basalt, peridotite and clay minerals. Granite, basalt, peridotite and clay minerals are pulverized and prepared into 1 cm granular shape. Weigh 15kg of granular granite, 12.5kg of basalt, 12.5kg of peridotite, and 15kg of clay minerals; then inject 4kg of 99% concentrated sulfuric acid, and the ingredients contained in the rocks and clay minerals are dissolved; then, add 10kg The water is stirred repeatedly to fully dissolve the ingredients in the rock and clay. After standing still for several days, the precipitated residue is filtered and separated from the aqueous solution to obtain the mineral composite material.

[0045] The mineral composite material prepared above was diluted 1000 times with pure water, and the metal components in the mineral composite material were quantitatively analyzed with the ICP emission analysis device VISTA MP-X according to the ICP emission analysis method. Potass...

Abstract

The invention discloses a mineral composite material and its application in sewage treatment. The mineral composite material is composed of granite, basalt, peridotite, clay minerals, water and inorganic acid. The parts by weight of each component are: 10-20 parts of granite, 8-18 parts of basalt, 8-18 parts of peridotite, 10-20 parts of clay mineral, 5-15 parts of water and 0.5-8 parts of inorganic acid. The components are pulverized and mixed; adding concentrated hydrochloric acid or concentrated sulfuric acid to dissolve the components; adding water and stirring to fully dissolve; standing still and filtering to remove residues to obtain the mineral composite material. The mineral composite material of the invention can be used to remove fluorine element, hexavalent chromium element and lead element in sewage, and can also reduce TOC and BOD content in sewage.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a mineral composite material and its application in sewage treatment. Background technique [0002] At present, domestic and foreign sewage treatment methods can generally be divided into physical treatment, chemical treatment and biological treatment. In the physical treatment method, the floating suspended substances are generally removed by filtration and coagulants. The commonly used coagulants include aluminum sulfate, polysalt aluminum, first iron sulfate, second iron sulfate, and second iron salt Inorganic coagulants such as cationic, anionic and nonionic polymer coagulants. However, although these coagulants can coagulate and precipitate suspended substances, they cannot remove soluble pollutants. Generally, biological treatment methods such as activated sludge method, loose water filter bed method or anaerobic digestion method are used for microbia...
