Abstract

PURPOSE:To obtain water of high degree of softening without using a forcible dissolving means by treating water in an apparatus provided with a calcined bone layer comprising granular bone calcined to an inorg. material to the downstream side of the layer of an adsorption body such as activated coal, ion exchange resin, etc. CONSTITUTION:A group of raw bone 2 of fish or cow, etc. is converted to an inorg. material by holding it between electrodes 3, 3 in a furnace 1, heating it at ca. 900 deg.C by applying high voltage between the electrodes and burning the bone for ca. 1hr in this state; the product is then crushed to 2-8mm. grain size to obtain granular product. The water introduced from an inlet port 41 of water rises upward through a space between an external periphery of a filter 5 and internal periphery of a case 4 of the main body as expressed by the arrow mark and flows into a filter 5 through an introducing hole 52, intrudes into a zone beneath the expanded resin 30, and is softened by the layer 31 of an ion exchange resin. After the water is filtered by a layer 32 of activated coal, the water contacts with granular calcined bone 33 to elute the hardness component, intrudes then into a pipe 6 through the expanded resin 34 and is conducted to a water discharge pipe 42.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water treatment device, and more particularly to a water treatment device that hardens water by dissolving an appropriate amount of hardening components such as phlegmon in purified water.

In recent years, due to environmental deterioration, water sources such as rivers have become contaminated, and the quality of tap water distributed to general households has deteriorated significantly.

On the other hand, chlorine, which is added at water treatment plants to sterilize raw water taken from rivers and the like, causes tap water to have a chlorine odor and an unpleasant taste. In order to remove chlorine and trace amounts of organic substances that cause this odor and unpleasant taste, tap water is purified by passing it through an adsorbent layer made of activated carbon or ion exchange resin at each household faucet. However, the ion exchange resin softens the water by removing most of the hard components such as calcilum and magnesium, which are closely related to the taste of the water. Therefore, efforts have been made to improve water quality by bringing purified water into contact with minerals containing hardness components, such as maifan stone.

However, minerals such as the above-mentioned Maifan stone elute a small amount of hardness components, and simply bringing water into contact with Maihan stone does not dissolve the hardness components.Therefore, attempts have been made to contact the minerals with water while stirring. A sufficient dissolved concentration of hardness components has not yet been detected.

The inventor focused on the fact that moxibustion substances also contain hard components such as calci, magnesium, and magnesium, and developed a substance containing hard components that are highly soluble in water after softening. As a result of extensive research to obtain this, it was discovered that heat treatment of bone increases the solubility of hardness components, leading to the present invention.

An object of the present invention is to elute hardness components from natural substances in order to obtain appropriately hardened water without using forced dissolution means such as stirring.

The technical means of the present invention for solving the above problems is to provide a charred bone layer formed by mineralized granular charred bone on the downstream side of an adsorbent layer of ion exchange resin, activated carbon, etc. The hardness component is eluted depending on the layer.

According to the above-mentioned technical means of the present invention, when passing through an adsorbent layer such as ion phase detector F and activated carbon and passing through a layer of burnt bones, ) Since the hardening components are naturally eluted, hardened water can be obtained without the need for forced dissolution means such as stirring as in the past.

More specifically, water flowing into the water treatment apparatus of the present invention is softened by passing through an adsorbent layer consisting of a softening agent such as an ion exchange resin and zeolite, and a diaphragm such as activated carbon and 1111 carbon. Through filtration, substances that give off odors and unpleasant tastes are removed, but the hardness components that are closely related to the taste of water, such as calcilum and sodium, which are originally contained in tap water, are removed by the above-mentioned ion exchange resins, etc. Most of the hardness is removed by the softener (water with very low hardness tastes like boiling water and is not tasty).
. Therefore, an appropriate amount of the hardness component is dissolved again through the burnt bone layer.This burnt bone layer will be explained in more detail.

Specifically, the above-mentioned burnt bones are prepared by placing a group of raw bones (2) of fish or cow etc. in a furnace (1) as shown in FIG.
3) , (3) Place it in between and apply a high voltage between the two poles to a high temperature of about 900 degrees, burn it in this state for about an hour to make it inorganic, and then crush it into pieces with a size of about 2 mm to 8 mm. It is made into fruit granules.

A water treatment device as an embodiment of the present invention using the above-mentioned burnt bones has a structure as shown in FIG. It consists of a cartridge-type filter (5), and is filled into the filter (5) with two burnt bones.

The filter (5) covers the upper end opening of a bottomed cylindrical container (51) with a lid (53) having a plurality of inflow holes (52), (52), and connects the lid (53) to the container (51). ) A pipe (6) extends through the bottom wall of the pipe (6).

In addition, the above inside the container (51), (outside (111) of Eve (6)
1) From the upstream side of t1, foaming resin (30), ion exchange resin (31), and activated carbon (32) are sequentially filled,
Downstream thereof, charred bone (33) in the form of fruit particles is filled, and further below that, foamable resin (34) is spread. Further, near the lower end of the pipe (6), through holes (131) and (Ell) are bored for introducing water into the pipe.

” To describe the actual water treatment using water treatment equipment, Part 2
As shown in the figure, the water taken in from the water inlet (41) located at the bottom of the main body case (4) flows between the outer periphery of the filter (5) and the inner periphery of the main body case (4) as shown by the arrow. An inflow hole (52) ascends within the gap and is bored in the lid (53).
, (52) into the filter (5), enters below the foamable resin (30), and enters the ion exchange resin (3).
After being softened by the layer 1) and filtered through the layer of activated carbon (32), it comes into contact with the charred bones (33) to elute the hard components, and the foamed resin (34) below is softened and filtered through the activated carbon (32) layer. It enters the Nokuib (6) mountain through the through hole (6 ()), and is finally led to the water outlet pipe (42).

Next, the test results of suspected component dissolution in the treated water that passed through the water treatment apparatus will be described in comparison with conventional tests.

For the test, in the case of the present invention, the position obtained by heat-treating raw fish bones by the method described above was placed at a distance of about 2 mm to 8 m.
Using a filter filled with 200 g of pulverized granules of 1.5 m, tap water at a temperature of 26 degrees was passed through the filter at a rate of 2 liters per minute for 30 minutes, then 3 liters of water was sampled. It was water.

In addition, a conventional one for comparison was one in which 3 kg of mineral rhusium carbonate was filled in place of the 200 g.

The results are shown below: (1) Calsulam content: Example of the present invention - Φ4 mg/l Conventional: Not detected (2) Magnesium content: Example of the present invention * a, 2 B/1 Conventional product... Not detected (3), Phosphorus compound content (as phosphorus) Example of the present invention... O, l 2n+g/l Conventional product...
・Not detected (4), Potassium content in the example of the present invention...4, 4+ng/I Conventional -OψRed Not detected (5), Storium content in the example of the present invention... φ49mg/l conventional type ・
...Not detected.

In addition, even with the above-mentioned conventional method, if a structure is used in which mineral lucium carbonate is immersed in water for about 30 minutes and then water is passed through it, hardness components are detected, and mineral carbonate is extracted while stirring the water. When brought into contact with calcilum, hardness components are detected even if the contact time is within 30 minutes.

As described above, according to the water treatment device of the present invention, the water that has passed through the adsorbent layer of activated carbon, ion exchange resin, etc., is absorbed when passing through the mineralized layer. Since hard components such as calcium and magnesium can be naturally eluted from the position at the above-mentioned ratio, appropriately hardened water can be obtained without the need for forced dissolution means such as stirring as in the past.

Furthermore, the above configuration of the present invention has the following advantages.

In water treatment equipment that uses minerals such as maifan stone, the solubility of hard components is low, so it is necessary to increase the contact time between the water and maifan stone during the process of passing through the equipment, and the flow path is inevitably long. However, in the case of the water treatment equipment of the present invention, the hardness components can be naturally eluted even if the contact time with water is short because the water treatment equipment of the present invention has high redissolution characteristics. Therefore, there is no need to lengthen the flow path and there is no need to worry about complicating the device.
