Description of the Related Art Wastewater from factories and septic tanks is generated from all corporate facilities irrespective of the quantity, but if discharged directly into rivers, the rivers and groundwater will be polluted and the local environment will be deteriorated. . Therefore, it is an urgent task for each company to equip the sewage water purification equipment that is highly effective and environmentally friendly. Pollution of rivers and the like caused by domestic septic tanks and domestic wastewater is also a serious problem.

み、無機物質による環境汚染は悪化する一方である。These contact purifying materials decompose pollutants in sewage by biological treatment with microorganisms attached to the contact purifying materials, and reduce the sewage to inorganic substances. Therefore, at present, harmful inorganic substances digested and reduced by microorganisms are discharged as they are. As a result, harmful inorganic substances such as ammonia nitrogen, phosphorus, dioxin, and trihalomethane that flow into local rivers, groundwater, seas, and lakes increase year by year, and eutrophication of rivers and other substances progresses. It is getting worse.

It is indispensable for food factories, sake brewers and drinking water manufacturers to secure high quality water sources in order to improve the quality of their products, and various measures have been taken to achieve this. Furthermore, it has been pointed out that drinking water is poor in ordinary households, especially in urban areas, and there is a strong demand for easily obtaining delicious water. There is also a great deal of interest in purifying fish farms and pool water as well as drinking water.

The present invention is characterized in that, by adding a volcanic ash and a required amount of water to a crushed natural mineral and kneading the resulting mixture, the glassy material in the volcanic ash is dissolved to make it porous. There is no particular limitation as long as it has a purifying action as a natural mineral,
Diatomaceous earth and Andosol are suitable because they have a high purification effect of sewage, and these diatomaceous earth and Andosol are used alone or in combination.

多孔質の接触浄化材を得ることに特徴を有する。Although it is well known that diatomaceous earth and andosol have a higher purification effect on sewage and the like than before, it has been difficult to remove impurities as a contact purification material and to form the porous material. For this reason, diatomaceous earth and andosol have been mixed with highly viscous clay and fired, but the clay mixed for shaping becomes speculative and has no air permeability, suitable for the survival of microorganisms, Moreover, a porous material having an adsorption ability could not be obtained. The present invention is characterized in that by mixing and firing volcanic ash, a porous contact purification material is obtained from diatomaceous earth and / or andosol.

表を表１に示す。Diatomaceous earth is a light-colored soft siliceous rock mainly made of diatom shells and has a high adsorption capacity. The diatoms that are the raw materials are the two most important groups of plankton, unicellular algae made by combining two proteinaceous small shells, which are deposited as remains and formed as soft rocks or clay Things. Diatomaceous earth includes marine species and freshwater ones, and freshwater ones are superior in quality. Pure diatom shells are 94% silicon dioxide and 6% water, but natural diatomaceous earth contains impurities, so its components also differ depending on the place of origin. Table 1 shows a composition table of the diatomaceous earth used in the present invention.

す。[0014] Ando soil is a soil having a humus-rich, black and soft surface soil, and contains silicon dioxide and aluminum oxide as main components. This Ando soil occupies about 15% of Japan's land, and soft volcanic ash erupted from a volcano about 100 million years ago thickly drops on overgrown kayaks and other vegetation on the earth, and it has been about 5000 years or more. During burial, the plant undergoes hydrolysis and changes to a slightly acidic black humic substance. Table 2 shows a composition table of the Andosol used in the present invention.

の粒状又は塊状に割砕して多孔質の接触浄化材を得る。The diatomaceous earth and the andosol are ground to an appropriate particle size. The particle size is not particularly limited, but is preferably approximately the same as the volcanic ash particle size of 4 mm. First, these diatomaceous earths and an orchard earth alone or a mixture of both are mixed with volcanic ash and formed by adding appropriate water. In order to facilitate drying, it is appropriate to form a plate. After the molded article is dried, it is fired. The firing means is not limited, but firing at 1200 ° C. or higher is required. By firing at 1200 ° C. or more, the glassy material in the volcanic ash is dissolved to become porous. Therefore, it is appropriate that the firing time is sufficient for the glassy in the volcanic ash to be melted, specifically, firing for 3 to 4 hours. Then, after the heat is sufficiently reduced after firing, the powder is broken into predetermined granules or blocks to obtain a porous contact purifying material.

Therefore, while being suitable for the survival of microorganisms for sewage purification, the contact purification material itself has a high adsorption action, and can adsorb and remove harmful inorganic substances digested and reduced by microorganisms. It is also suitable for use in purifying drinking water and the like. Further, it also has a deodorizing effect, and can deodorize by adsorbing malodorous substances such as ammonia methyl captan, hydrogen sulfide, methyl sulfide and the like. In addition, a conventional sewage purification device or the like can be used, and the contact purification material according to the present invention may be used instead of the conventional contact material. Furthermore, the contact purifying material according to the present invention may be merely charged into a sewage tank, a drinking water tank, a container, or the like in an appropriate amount.
