Description

[0001]
[Technical field to which the invention belongs]
TECHNICAL FIELD The present invention relates to a production method and a handling method of mixing a charcoal powder and various artificial zeolites that create an optimum synergistic effect for drinking water and other water purification.
[0002]
[Conventional technology]
Water purification materials made from charcoal are generally recognized, but there are large differences in quality and shape depending on the charcoal raw materials, manufacturing technology and manufacturing method.
[0003]
As the charcoal used at the end of water purification, those produced mainly from activated carbonized coconut shells and coconut shells to produce particles of several millimeters to several tens of millimeters are often used.
[0004]
Natural zeolites are used to adsorb and remove heavy metals, ammonium ions, phosphorus ions, etc., chemical fertilizers and pesticide residue influx, but the expected effects are not necessarily obtained.
[0005]
Artificial zeolites have been manufactured for about 10 years, and have high cation exchange capacity and are excellent at adsorbing and removing heavy metals, ammonium ions, phosphorus ions, etc., chemical fertilizers and pesticide residue influx, but powder for water purification applications Therefore, it is necessary to make the granulation moderate, and the granulation is not used because a high-quality adhesive has not been developed. Development of high quality adhesives is awaited.
[0006]
Thinned charcoal, etc. is inferior in fiber quality to coconut shell or coconut shell, so when activated carbon is used, it does not increase porosity compared to before activation, and it does not increase specific surface area, so it is used as activated carbon Hard to do.
[0007]
As a result, it is one of the reasons why carbonized wood is not widely used in spite of using thinned wood.
[0008]
[Problems to be solved by the invention]
Charcoal powders and artificial zeolites have problems such as that few of them are suitable for use as drinking water and other purification materials and their expected effects cannot be obtained.
[0009]
In the present invention, charcoal powder and various artificial zeolites are mixed in an appropriate amount for each application, granulated to an appropriate size in order to improve the usability, and the effects of using the charcoal powder and various artificial zeolites are synergistically used. It is an object of the present invention to provide a manufacturing method and a method for using the same that solve the above-mentioned problems.
[0010]
[Means for solving the problem]
For drinking water and other purification, an adhesive is added to knead and manufacture charcoal powder and various artificial zeolites into granules suitable for each application, and the kneaded product is dried to produce a water purification material Sui Zeo.
[0011]
In order to improve usability, the Sui Zeo materials to be manufactured will be manufactured for each application.
[0012]
[Embodiment of the invention]
The present invention is a method of granulating thinned wood, general wood, bark wood, and the like obtained by carbonizing in a carbonization furnace and appropriately finely pulverizing and manufacturing them with various types of artificial zeolites according to the purpose of water purification. In order to do this, it is hardened with a synthetic adhesive and granulated to produce a water purification material, Sui Zeo material.
[0013]
The carbonization condition of the charcoal is preferably as high as the carbonization temperature, but the cedar thinned wood is limited to about 700 ° C.
[0014]
The fine pore diameter is about 20 to 1000 angstroms for thinned charcoal, about 5 to 100 angstroms for artificial zeolite, and it becomes about 5 to about 1000 depending on the combination, and various fertilizer ions, pesticide ions, heavy metal ions, Suitable for absorbing organic matter and sludge.
[0015]
The cation-exchange capacity of charcoal is preferably as high as possible, but thinned charcoal is only a few meq per 100 grams, so that performance cannot be expected.
[0016]
The pH varies depending on the production carbonization conditions, and the higher the carbonization temperature, the higher the pH. 700 ° C. is about 8.5.
[0017]
As for the artificial zeolite, the higher the cation exchange capacity is, the more preferable it is about 220 meq or more. The same is true for paper sludge incineration ash.
[0018]
Furthermore, it has been proven that about 420 aluminum-type artificial zeolites can be manufactured, and highly effective sui and zeo materials can be manufactured by mixing.
[0019]
When using Sui Zeo materials, granulate the water specific gravity to 1.2 to 1.3 or more to prevent Sui Zeo from floating.
[0020]
Depending on the water quality of the place where it is used, sodium type, calcium type and magnesium type can be used alone or in combination.
[0021]
The charcoal powder and the artificial zeolite manufactured under the conditions of the above item numbers 0013 to 0020 are mixed and stirred, a synthetic adhesive is added, and the mixture is granulated to produce a Sui zeo material.
[0022]
It is necessary to granulate to an appropriate size to shorten the residence time of the water stream.
[0023]
Next, the production apparatus will be described. However, any apparatus can be used as long as it can granulate and dry after adding a synthetic adhesive to charcoal powder and artificial zeolite, mixing and stirring, and there is no particular limitation.
[0024]
There is no particular limitation on the amount used, depending on the place of use.
[0025]
The place of use is not particularly limited, and it can be used as appropriate, such as a place for conventional activated carbon, a place for pretreatment, and a place for newly installing.
[0026]
[The invention's effect]
It can absorb and remove residues such as heavy metals, ammonium ions, phosphorus ions, etc., chemical fertilizers and pesticides, which had been difficult to adsorb and remove until now.
[0027]
The use of charcoal powder can be expanded and materials made from various incineration ash can be converted into artificial zeolites and recycled, contributing to a recycling-oriented society.
[0028]
Above all, it leads to a safe supply of drinking water, which can lead to humans, animals and other uses that are very favorable for us.
