Abstract

PROBLEM TO BE SOLVED: To provide a material for purifying water bottom sludge by an oxygen generating material, which is a material for purifying/decomposing the water bottom sludge without requiring advanced equipment cost, and purifies/decomposes environmental pollution caused by garbage, domestic sludge, agricultural sludge, industrial sludge, sewage sludge and the like to provide odor elimination, protection of fishes, and environment where plants can live.SOLUTION: Components of a peroxide and wood vinegar are made to be contained in and adsorbed by porous materials of diatomaceous earth, burned oyster shells, zeolite, wood chips, sawdust, and a plant extract, thereby removing chlorine and carrying out an oxidation catalytic reaction. Odorants are oxidatively decomposed, whereby odorants which undergo the oxidation catalytic reaction are decomposed. The habitat environment of effective microorganisms is prepared by decomposition of a putrid odor of protein and of animal excrement, adsorption and decomposition of pesticide residues such as nitrogen and phosphorus, adsorption of harmful substances such as spilled oil, bacteriostatic action, and acidity control, thereby exhibiting an excellent effect. The superfine and superporous natural materials adsorb and decompose the pesticide residues and heavy metals. Growth of various germs, which is a secondary source of smell, is prevented to provide deodorizing effect. Zeolite removes ammonia and nitrogen. Adsorptive removal of heavy metal ions, decolorization and purification of dye wastewater, treatment of radioactive waste water, softening of hard water are carried out. Ammonia gas is adsorbed, and oxygen and nitrogen are separated as separation of gas. Deodorizing effect due to adsorption of ammonia, nitrogen and phosphorus improves the environment to contribute to protection and preservation of the environment.

Description

The present invention relates to contribution to environmental improvement, protection, and maintenance by a purification treatment technique related to water bottom sludge decomposition using an oxygen generating material.
By submerging the bottom sludge in a porous material of microorganisms and inhabiting it, the organic matter in the bottom sludge is decomposed and reduced to carbon dioxide and water.

Underwater sludge has been aggravated by raw garbage, domestic sludge, agricultural sludge, industrial sludge, and sewage sludge, so that oxygen in the bottom is consumed, causing damage to the fishery and living environment.
Contamination of bottom sludge has caused problems such as bad odor, fish and plants.
Although equipment and equipment have been introduced as countermeasures, they have not been able to deal with sufficient sludge treatment.

  The present invention makes use of Japanese Patent Application No. 2005-365886 of the same inventor to adsorb dirt, chemical substances, heavy metals, phosphorus, nitrogen, ammonia, porous materials, heavy metals and other dirt, and to naturally decompose microorganisms and bacteria. By changing to nutrients of microbial carrier, water quality is purified and the natural environment is restored.

Diatomaceous earth is a porous diatomaceous earth produced from Kitaakita City, Akita Prefecture. Zeolite is a mineral produced from Futatsui, Noshiro City, Akita Prefecture. It is desirable to mix these. 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 widely used in processing applications involving environmental hormones.

An object of the present invention is to provide a combination of the function and performance of wood vinegar and the usefulness of diatomaceous earth, zeolite, and sawdust as an environmental improvement material.

Although many proposals have been made and put into practical use for the treatment of submerged sludge, it required capital investment and a large amount of money and manpower, 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 calcined oyster shells, diatomaceous earth, and zeolite are pulverized and calcined 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 bottom sludge purification material by the oxygen generating material of the present invention is an environmental purification material that decomposes raw garbage and sludge and absorbs and deodorizes deodorant. Features.
The wood vinegar is infiltrated into a combination of calcined oyster shell / diatomaceous earth, 1-5 mm of zeolite particles and sawdust, wood debris, rice husk particles and plant extract as a carbon source. There is sludge decomposing action due to the action of microorganisms containing oxygen generating materials in purification of substances such as nitrogen adsorption and phosphorus adsorption and water purification that are the cause of pollution.
Utilize agricultural waste, forestry waste, industrial waste, etc. Promote zero emissions in a resource recycling society.

The results of the composition analysis of the resources are shown in [Table 1] and [Table 2].

To obtain environmental improvement materials from the synergistic effect of microorganisms by the useful characteristics of natural baked oyster shells / diatomaceous earth, zeolite, sawdust, wood fragments, rice husks, plant extracts and the oxygen generating material adsorbed and retained in the pores I was able to.
Due to the characteristics of natural resources, a unique action was discovered.

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

By attaching, planting, and penetrating useful microorganisms to the porous body, oxygen is generated at the bottom of the water, and sludge organic matter is decomposed.
The bottom sludge purifying material according to the present invention relates to an environmental material characterized by hydrogen sulfide / phosphorus adsorption and the like, which are excellent in safety and economy, low in cost and excellent in practical use.

It consists of a mixture of calcined oyster shell, diatomaceous earth, zeolite, sawdust, wood debris, rice husk, plant extract, and wood vinegar.

The water bottom sludge purification material of the present invention is characterized in that it contains one or more kinds of generating materials selected from zero emission materials of wastes of peroxide materials and natural porous materials.

By spraying the water bottom sludge purification material by the oxygen generating material according to the present invention, the oxidative decomposition action of the organic matter of microorganisms acts on raw garbage, domestic sludge, agricultural sludge, industrial sludge, sewage sludge, etc., and sludge is reduced and decomposed.
