DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a water treatment apparatus used for treating sewage and the like.

[0002]

2. Description of the Related Art Conventionally, a chlorine-based disinfectant such as sodium hypochlorite is generally used for disinfecting secondary treated water such as sewage, tertiary treated water or industrial wastewater.

[0003]

However, when a chlorine-based disinfectant such as sodium hypochlorite is used, harmful substances such as trihalomethane are easily generated as by-products, which may adversely affect the ecosystem to which the water is discharged. is there.

For this reason, for the conventional disinfection of sewage treatment or factory wastewater, for example, as shown in FIG. 6, a pair of columns 1 support an ultraviolet lamp housed in a jacket 2 and irradiate the treated water with ultraviolet rays. Sterilization has been implemented.

According to the water treatment apparatus shown in FIG. 6 described above, when the jacket is broken, the lead wires of the lamps are laid in the same column, so that any of the jackets may leak. Then, there is a disadvantage that water enters all the jackets.

The present invention has been made in view of the above points, and does not cause secondary pollution caused by chemicals. If water enters a specific jacket, it may adversely affect other jackets. It is an object of the present invention to provide a water treatment device that can be safely implemented without any problem.

[0007]

According to the first aspect of the present invention, a light source support having a pair of columns is disposed inside water, and a plurality of ultraviolet light sources are provided at predetermined intervals on the columns. The present invention relates to a water treatment apparatus equipped with a. A watertight socket is arranged at one end of a support at a predetermined interval in the apparatus, and a lead wire insertion hole is formed at a position corresponding to the socket at one end of the support at the other end. In addition, a socket is arranged inside the support of the lead wire insertion hole, and a pipe is arranged from the outside of the support corresponding to each lead wire insertion hole, and the lead wire connected to each light source is inserted into each pipe and configured I have.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. In the figure, reference numeral 11 denotes a box-shaped water treatment apparatus main body, in which an injection hole 12 is formed on a longitudinal side wall, and is poured on a side wall on the opposite side of the water treatment apparatus main body 11 in the longitudinal direction. It has a hole. Reference numeral 13 denotes a light source support housed inside the water treatment apparatus main body 11,
It has a pair of columns 14 and 15. The supports 14 and 15 are made of, for example, stainless steel.
The holes 16 are provided at predetermined positions in
Is provided. The struts 14, 15 are prismatic,
Any of the round pillars may be used.

Reference numeral 17 denotes a cap which is fitted and supported in the hole 16 of the column 14 at one end, and is made of, for example, stainless steel. Further, as shown in FIG. 5, a support pillar 25 may be provided with a jacket support ring 25, and the jacket may be supported by the jacket support ring 25. Reference numeral 18 denotes a jacket support which is supported in a water-tight manner in the hole 16 of the support 14 at the other end, and has a funnel shape, for example. Reference numeral 20 denotes a cylindrical jacket which is mounted between the jacket supports 17 and 18 at both ends in a watertight state and transmits ultraviolet rays, and is made of, for example, quartz glass. Reference numeral 21 denotes a germicidal lamp mounted on the inside of the jacket 20, which is constituted by using, for example, a 65-watt germicidal light source. 22 is a socket,
23 is a packing sandwiched between the jacket support 18 and the jacket 20, and 24 is a fastener.

Reference numeral 26 denotes a pipe provided outside the column corresponding to each hole, and is formed by inserting a lead wire 27 connected to each light source. Since the structure shown in FIG. 1 is configured using four light sources, it is configured using four pipes. The number of light sources and pipes is increased or decreased according to the amount of water to be treated.

[0011] It should be noted that a box-shaped water treatment apparatus main body may not be provided, and the germicidal light source mounted on the above-mentioned jacket may be arranged inside treated water for directly treating.

[0012]

EXAMPLE A water treatment device is constructed by mounting a sterilizing light source of, for example, 65 watts inside a jacket, and when the device is disposed inside the treated water, E. coli and the like are treated by 253.7 nm of ultraviolet rays from the sterilizing light source. Is done. For example, initially 4.0 × 10 ⁴ (pieces / 100
(ml), the bacteria are sterilized with a contact time of 6 to 8 seconds at a sterilization rate of about 99.9%.

[0013]

According to the present invention described above, since no chemicals are used, secondary pollution does not occur, and when water enters a specific jacket, other jackets are not adversely affected, and safety is ensured. There are special effects that can be implemented.
