Abstract

PROBLEM TO BE SOLVED: To provide an environment where odors are eliminated, fishes can be protected and plants can grow, by improving environmental pollution, caused by sewage, by a water purifying filter medium technology at a low cost without requiring high equipment cost.SOLUTION: Components of wood vinegar are contained and adsorbed in a porous filter medium of diatomaceous earth, zeolite, wood pieces, sawdust, and burned plant particles/burned chaff particles, thereby causing chlorine removal and an oxidation catalytic reaction. A capacity technology is developed which decomposes odorants, which are oxidatively catalyzed and reacted, by oxidatively decomposing them. The habitat environment of effective microorganisms is prepared by decomposition of putrid odor of proteins, excrement of animals and the like, adsorption and decomposition of pesticide residues such as nitrogen and phosphoric acid, adsorption of harmful substances such as spilled oil, bacteriostatic action, and acidity adjustment, thereby exhibiting excellent effect. An ultrafine and superporous natural material adsorbs and decomposes pesticide residues and heavy metals, and prevents the propagation of various germs as the secondary generation source of smell to exhibit a deodorizing effect. In porous filter medium treatment, ammonia and nitrogen are removed; heavy metal ions are adsorbed and removed, dye wastewater is decolored and purified, radioactive waste water is treated, and hard water is softened; and ammonia gas is adsorbed and oxygen and nitrogen are separated as the separation of gases. A deodorizing action and environmental improvement by the adsorption of ammonia and nitrogen are performed to contribute to environmental protection and conservation.

Description

In the present invention, the water purification technology contributes to environmental improvement, protection, and conservation by improving the porous structure filter medium.
By infiltrating and infiltrating a porous body with microorganisms, the biological purification performance of the effective area is physically improved for the improvement of filtration accumulation and the inhabitation and establishment of beneficial bacteria. The present invention relates to a water purification filter material that decomposes and reduces organic matter in sewage into carbon dioxide and water.

Due to the aggravation caused by raw garbage, domestic sludge, agricultural sludge, industrial sludge and sewage sludge, sewage environmental problems are occurring in the habitat of bad odors, fish and plants.
Equipment and equipment have been introduced as countermeasures, but sufficient sewage treatment measures have not been implemented.

The present invention makes use of the patent publication 2007-301543 of the same inventor, and a porous body of dirt / chemical substance / heavy metal / phosphorus / nitroso / ammonia adsorbs dirt such as heavy metal to naturally decompose microorganisms and bacteria. By changing to nutrients of microbial carrier, water quality is purified and the natural environment is restored.

In the water purification treatment filter medium of the present invention, it is preferable to use porous plant fired grains and rice husk fired grains. In addition, porous diatomite from Kitaakita City, Akita Prefecture. Zeolite is a mineral produced from Futatsui, Noshiro City, Akita Prefecture. It is desirable that these are single or mixed. For wood vinegar, use local products from Kitaakita City, analyze it using the method of Japan Wood Vinegar Association, and use it with the quality specified in the plan for wood vinegar. , Effective in deodorizing, antibacterial and the like. (For the wood vinegar, use the certified products of the Japan Wood Vinegar Association)
This new technology can be extended to processing applications involving environmental hormones.

An object of the present invention is to provide the water purification filter material of the present invention as an environmental improvement material by combining the functions and performances of wood vinegar and the singularity / usefulness of diatomaceous earth, zeolite and sawdust.

As for sewage treatment, many proposals have been made and put into practical use, but it required capital investment, great expense and human power, but it caused pollution to the ecosystem.
In addition, water sewage and purification of heavy metals were released into rivers, causing problems with natural pollution, environmental destruction caused by secondary products, water pollution, and foul odors.
A treatment method in which diatomaceous earth and zeolite are pulverized and fired at 800 ° C. or higher. It is characterized by mixing 60 to 80% by weight of the pulverized substance and 20 to 40% by weight of the mixture to improve the function of the porous structure.
The water purification filter material of the present invention is an environmental purification material that decomposes sewage and absorbs and deodorizes deodorant.
Combined with diatomaceous earth, zeolite particles 1-5mm, and sawdust, wood debris, rice husk fired particles and plant fired particles as carbon source. There is sludge decomposition action by microbial action in purification of substances such as nitrogen and phosphorus that are the cause of sewage and purification of water. After use, it is reduced as a soil conditioner and promotes a resource recycling society.

The large and small pore formation increased the physical filtration performance, and the increase in the surface area promoted the growth of beneficial bacteria and increased the biological filtration performance, thereby obtaining a water purification filter medium.

It is possible to obtain an environmental improvement material by the synergistic effect of microorganisms adsorbed and retained in the pores and the characteristics of useful porous filter media of natural materials diatomaceous earth, zeolite, sawdust, wood debris, burned rice husk grains and plant burned grains Due to the characteristics of the natural resources that were produced, a unique action was discovered.

Furthermore, it was discovered that a sustainable effect can be obtained as an environmental improvement material.

Decompose organic matter in sewage by attaching, planting and infiltrating useful microorganisms into the porous body.
The water purification filter medium according to the present invention relates to an environmental agent that is excellent in safety and economy, is low in cost, and is characterized by oxidative decomposition excellent in practical use.

Sewage and harmful substances are removed with a porous filter medium consisting of diatomaceous earth, zeolite, sawdust, wood fragments, burned rice husks, plant burned grains, and wood vinegar.

The water purification material of the present invention is based on a natural porous material filtering material.

With the water purification filter medium according to the present invention, the formation of large and small pores, the physical filtration accumulation reaction, the biological filtration performance by the effective area of beneficial bacteria habitat, the oxidative decomposition action of organic matter of microorganisms, and the water purification is porous Sewage is reduced and decomposed by the filter material reaction.
