FIG. 2 is a schematic sectional view of the embodiment, FIG. 2 is a plan view thereof, and FIG. 3 is a schematic enlarged sectional view of a magnetic water treatment device.

The first embodiment is similar to that shown in FIGS.
As shown in FIG. 1, a non-magnetic container 2 made of a ferrous metal or the like is attached to a pipe 1 through which water to be treated, such as treated wastewater, river water, pond water, lake water, etc., flows. Desired pieces (three in the example shown) in magnetic container 2
And a calcium hypochlorite-filled container 4 is inserted and installed at the ceiling of the container so as to face the non-magnetic container 2.

The calcium hypochlorite-filled container 4 comprises:
A large number of sewage introduction holes 4a are formed in the side and bottom surfaces, and the upper end surface is formed of calcium hypochlorite Ca (Cl).

There is provided a monovalent silver-containing ion glass inlet 8 for charging the valent silver-containing ion glass 7. The monovalent silver-containing ion glass 7 is supplied when a large amount of algae or the like is generated and the sewage becomes dirty. Usually, only the semiconductor ceramics 6 is filled. Reference numerals 9 and 10 denote mesh filters for preventing the semiconductor ceramics 6 and the monovalent silver-containing ion glass 7 filled in the nonmagnetic container 2 from flowing out of the container.

The magnetic water treatment device 3 has a non-magnetic pipe 1 having a watertight structure as shown in FIG.
1, a plurality of hollow disk-shaped permanent magnets 12 are stacked and coaxially connected in the axial direction of the non-magnetic pipe 11 with a magnetic plate (iron plate) 13 interposed therebetween. Each hollow disk-shaped permanent magnet 12 is a non-magnetic pipe (non-magnetic cylinder).

In the sterilizing and purifying apparatus having the above-mentioned structure, when water to be treated such as treated wastewater, river water, pond water, or lake water is introduced into the non-magnetic container 2 through the pipe 1, the introduced water to be treated becomes an arrow. As shown in the figure, the water flows around the magnetic water treatment device 3, and at this time, the non-magnetic pipe 1
1 passes through a multipole magnetic field generated by a large number of hollow disk-shaped magnets 12 arranged in a stack, so that the magnetic dipoles of water molecules in the water to be treated interact with the multipole magnetic field, The kinetic energy of the water changes into electric energy, activating water molecules. As a result, to cause physical changes in the spin system of water molecules, various physical changes are caused to ionic compounds, bacteria, and algae suspended in the wastewater, and the wastewater is reformed and activated. Can be purified.

When the magnetic energy generated by the magnetic water treatment device 3 acts on the semiconductor ceramics 6, electrons e- ¹ jump out of the semiconductor ceramics 6 and act on ionic compounds, bacteria and algae suspended in water. Then, the electron e- ¹ is robbed from these, and the components constituting these substances are changed to a free radical state. As a result, the free radical components combine with other free ions to decompose and kill or detoxify chlorine compounds, bacteria, algae, and bacteria in wastewater, and at the same time, agglomerate particulate water suspension. Promotes sedimentation and filtration,
Purify sewage.

In addition, since the inner core 25 is loosely inserted with respect to the outer core 23, the micro-vibration is continuously caused by the kinetic energy of the flowing water to be treated.

Therefore, the water molecules of the water to be treated flowing through the water flow while repeating the oscillation of the polar axis due to the interaction with the fluctuating multipolar magnetic field, and the kinetic energy of the water molecules is converted into electric energy. It turns into energy and water molecules are activated. As a result, to cause physical changes in the spin system of water molecules, various physical changes are caused to ionic compounds, bacteria, and algae suspended in the wastewater, and the wastewater is reformed and activated.
