Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field J] The present invention relates to a method for purifying drinking water, and more specifically, it relates to a method for purifying drinking water using a treatment substance containing natural shellfish fossils as a treatment agent. This relates to a processing method.

[Prior art 1: A method for improving water quality by refining natural shellfish fossils into treated substances is disclosed in JP-A-51-141457 (Method for improving water quality using shellfish fossils), for example. There is. This method involves pulverizing natural shellfish fossils into rough sand-like particles and then heat-treating them to avoid destroying the single molecule structure.
Crystal water contained within a certain effective diameter is removed, and further 20
By spraying the product processed into a fine powder with a mesh size of 0 or more into the water to be improved (treated), and adding ferric chloride or hydrochloric acid as necessary, adsorption, ion exchange, and physical , chemical actions are promoted in parallel, and at the same time, coagulation and precipitation occur rapidly, and the lignin, blood, printing ink, and paint contained in drinking water, sugar, sediment, sediment waste, or industrial wastewater. , cutting oil, gasoline, diesel oil, kerosene, heavy oil, mercury, cyanide, cadmium, chromium, lead, copper, iron, PCB, cooking oil, detergent,
In order to improve the single or mixed state of harmful substances such as urine (C treatment) in a short time and also remove odors, the supernatant water after treatment becomes mineralized, making it possible to reuse it as drinking water. ``A method for improving water quality using shellfish fossils, characterized in that the precipitate can be disposed of as mere soil.'' (Claims) However, depending on the composition of fossil shells and the method of refining them, good effects could not be obtained and practical use was lacking. In addition, the main components of shell fossils are destroyed due to the mixing of cupric chloride and hydrochloric acid, causing various problems.

Furthermore, conventional methods for refining natural shellfish fossils generally employ methods such as lime or sand grains. That is,
The crude ore shell fossils that have been roughly pounded in advance are dried with hot air using a hot air dryer, which is commonly used for producing lime and sand grains, and also using metal powder equipment, which is often used for producing iron powder and copper powder. The most common method is to grind it into a powder and refine it. According to this conventional method, each device and machine tool is manufactured for each purpose, so it is not suitable for producing shellfish fossils that contain many components.

This was reducing the value of the product. In addition, many problems arose, such as the extremely primitive manufacturing method and the inability to systematize storage management, making it unsuitable for long-term preservation, which made commercialization difficult.

Furthermore, conventional methods of purifying drinking water mainly involve using chemicals such as chemicals to filter turbid water, which destroys the original properties of water. Not only that, but it was considered impossible to return all of the odor, taste, and aroma to natural water.

[Problems to be Solved by the Invention] In order to solve this problem, it is necessary to use shellfish fossils that contain components suitable for water quality improvement, even if they are natural shellfish fossils.
It is necessary to refine and process this suitable shellfish fossil into a microscopic diameter that can be used as a treatment substance for water quality improvement, and this is the problem that the present invention aims to solve. In particular, the greatest challenge of the present invention is to return turbid water to natural water.

[Means for Solving the Problems] The present invention was developed in order to solve the above-mentioned problems, and involves refining and processing natural shellfish fossils containing mainly calcium carbonate and carbon dioxide into fine powder. The treated substance is the main component, and the treated substance is mixed into turbid water containing harmful components such as odor, discoloration, bad taste, and various bacteria, and these harmful components are removed by the physical and chemical effects of the treated substance. A drinking water purification method characterized by decomposition and removal,
Also, various nektons and plaktons in which the treatment substance is made of calcareous material, silicic acid, or the like.

Natural shell fossils containing algae and seaweed components are crushed into small grains or coarse sand-like coarse ore and dried naturally.
Dry with hot air at 20°C to 45°C (approximately 1°C, refine into powder, and further air classify to form i3 particles with a diameter of 0.10 μm.
It has been purified to a particle size of about 50.00 μm.

[Function] The natural shellfish fossil used in the present invention was mined from a shellfish fossil vein buried in the Toyama Prefecture region. The shellfish fossils buried in this region were mainly formed as a result of the physiological actions of animals, and it is said that these remains were mechanically sorted and sorted under the sea before being deposited on the ocean floor. There is. In other words, these shell fossils are made up of various nekton (shells, fish), plakton (microorganisms), algae, seaweed, etc. made of calcareous and silicic acid, which were buried alive due to changes in the earth's crust, and were deposited for about 80 million years. To date, it has been discovered that these fish and shellfish and organic substances have not turned into fossils, but have become crystals with tactile properties. be. Due to these factors, its main component, carbonic acid lucilum, is a collection of extremely fine particles secreted from proteins, and because it is in the form of arabite (decomposed stone), it is not susceptible to calcite (decomposition). Compared to those formed by stones),
A characteristic of shellfish fossils in this region is that they are far more active.

The results of a component analysis conducted by the Japan Fertilizer Inspection Association of the natural shellfish fossils from the Toyama region that have been purified and processed into powder are as follows.
