Abstract

PURPOSE: A method for manufacturing magnetic minerals is provided, thereby improving culture efficiency of microorganisms when the magnetic minerals are used. CONSTITUTION: A method for manufacturing magnetic minerals comprises the steps of: mixing ore-forming mineral powder such as rhyolite or dacite pumice stone, amphibole, olivine, biotite and volcanic ash soils with far infrared and negative ion irradiating mineral powder such as phyllite, pegmatite, quartz porphyry, tourmaline and jade; inserting organic acid such as citric acid, tartaric acid, succinic acid and fulvic acid, and chloric acid and sulfuric acid into the mixture to regulate pH value of the mixture to 1.5 to 2.5; stirring the mixture to prepare a gel type chelate mineral complex; adding magnetite and ferrite powder into the complex; adding bentonite as an inorganic binder and sodium alginate, chitosan resin, cellulose resin and starch as organic binder into the complex to prepare dough; processing pellets or pills using the dough; drying the pellets or pills at room temperature with hot wind, and magnetizing them.

Description

Manufacturing method of magnetic minerals

Organic acids and mines that produce Iv) After injecting aqueous solution and mixing with stirring, it is converted into chelate mineral complex salt of gel state and then magnetite ), Ferrite (MO.nFe₂O₃; M = Fe, Ba, Sr, etc.), and then mixed with a powder of magnetic material (bentonite) and sodium alginate (Binder) as a binder (Binder) Chitosan resin, cellulose resin, starch, and other aqueous solutions are added and stirred to make a dough, which is processed into pellet or annular form, dried naturally with hot air, and then magnetized. To prepare a magnetic mineral.

Japanese Patent Publication No. Hei 5-66199 A microbial culture tank for biological wastewater treatment, which has been installed and treated with bioreactors filled with humus pellets and rhyolite or sidewall pumice. Compared with the sludge method, the treatment efficiency is improved, but the mineral pumice mineral (浮石) Because of the lack of mineral supply ability to microorganisms, it took a long time to recover to a normal state in case of commissioning or abnormal operation. Especially, when using pumice with a low magnetite content, the microbial culture efficiency was not improved.

An object of the present invention is to propose a method for producing a magnetic mineral having excellent microbial culture efficiency using in the microbial culture process.

In order to achieve the above object, the present invention is to produce a mineral complex salt by injecting an aqueous solution of organic acid and mine to form a complex salt in the powder of coarse minerals containing a large amount of soluble mineral components and the powder of minerals generating far infrared rays or anions After mixing the powder of the magnetic material in the mixture and adding a binder and stirring to make a dough, processed it into spherical or annular shape, then dried naturally with hot air and then magnetized to produce a magnetic mineral with excellent microbial culture efficiency.

Magnetic minerals used in the microbial culture process in the present invention (磁性 Referring to the manufacturing method of the material in detail as follows.

1. For weathering, such as rhyolite or dacite-like pumice, hornblende, olivine, biotite, volcanic ash, etc. Coarse minerals that elute minerals easily One or more kinds of powders, feldspar, macromatite and elvan Stone, tourmaline, Powders of minerals that generate far infrared rays or negative ions, such as 王石, Tajing Stone, and Jade, are mixed.

2. Add water to 1 to adjust the water content to 40 to 60%.

3. Metal complexes in 2) Citric acid that produces 교반) 10-20% of organic acids such as tartaric acid, succinic acid, succinic acid, and fulvic acid are mixed and stirred.

4. In accordance with paragraph 3, hydrochloric acid ( Mines such as sulfuric acid and sulfuric acid I) Inject and stir while adjusting the pH in the range of 1.5 to 2.5 to convert the gel state into a chelate mineral complex salt state.

5. In accordance with paragraph 4, magnetite ; Powders of magnetic materials such as FeO · Fe₂O₃) powder, ferrous tetraoxide (Fe₃O₄), barium ferrite (Ba · 6Fe₂O₃), strontium ferrite (SrO · 6Fe₂O₃) at a ratio of about 10 to 50wt% Inject and stir.

6. Add Bentonite powder in 0.1 to 0.5% with inorganic binder and stir and mix.

The organic binder is used to prepare the dough while stirring by adding 0.02 ~ 0.05% of aqueous solution of sodium alginate, chitosan resin, cellulose resin, and starch.

8. Process the dough of Clause 7 into spherical pellets and annularly, and then naturally dry for 4 to 5 days, and then dry with hot air at 100 to 250 ° C to prepare dried pellets.

9. Magnetic dried minerals are prepared by magnetizing the dried pellets of Clause 8 to more than 300G (Gauss) in magnetic flux.

As is apparent from the above description, the magnetic mineral of the present invention is widely distributed in these fields because of its excellent microbial culture efficiency in microbial culture processes such as biological treatment of sewage and wastewater, biological deodorization treatment, and animal drinking water treatment. It is expected to be.
