る。Description: TECHNICAL FIELD The present invention relates to a method for sterilizing excess circulating water in excess of pond water and excess cooling water of a cooling tower.
従来、上述のような池水の過循環水やクーリングタワ
ーの冷却水の殺菌方法として液に紫外線を照射してあ
おこの発生を防止することや病原菌を死滅させることは
よく知られている。It is well known that, as a method of sterilizing the above-described circulating water of pond water or cooling water of a cooling tower, the liquid is irradiated with ultraviolet rays to prevent the generation of blue husks and to kill pathogenic bacteria.
然しながら、この紫外線を照射する方法では、液中の

洗浄に大量の水と大きな動力を要する。特に、クーリン
グタワー等で高所に処理施設を設けるものでは、施設費
も莫大となる難点がある。However, in this method of irradiating with ultraviolet rays, if the suspended matter in the liquid is not more than 10 μm, this blocks the ultraviolet rays, and even if it is effective against the baby etc., it is not possible to kill minute pathogenic bacteria. For this purpose, a sand filter that can capture even small suspended matter in the liquid may be used,
When using a sand filter, to capture even fine suspended matter,
Not only does it require a thick overlayer, which requires a large amount of wood, but when it becomes clogged, it requires a large amount of water and a lot of power to wash it for regeneration. In particular, when a treatment facility is installed at a high place such as a cooling tower, the facility cost is enormous.
この発明は、上述のような難点を解消したものであっ

うにしたものである。このように紫外線が照射された
液は、池中やクーリングタワーを経て再び第一段の浮上
材を用いた過機に還流するものである。The present invention solves the above-mentioned problems, and is a cartridge that is easy to recycle by removing clogging at the subsequent stage after removing large-sized suspended matter with an extremely lightweight and easy-to-handle floating material. I went through the formula precision machine, then
This solution is irradiated with ultraviolet rays. That is, the gist of the point is that when passing the pond water or the cooling water of the cooling tower, first pass it with a lightweight floating material, then pass the liquid with a precision machine using a cartridge type material, The liquid is irradiated with ultraviolet rays. The liquid thus irradiated with ultraviolet rays returns to the excess machine using the first stage levitation material again through the pond and the cooling tower.

せることができる。According to the present invention, since the large-sized suspended matter is removed by the machine using the primary levitation material, the fine suspended matter (about 1 mm is applied without burdening the secondary precision machine. )
Can be removed. Therefore, by irradiating the liquid of this precision machine with ultraviolet rays, it is possible to efficiently kill the blue pigment and small miscellaneous bacteria in the liquid without being blocked by the suspended matter in the liquid.

向上させたものである。A flow sheet of the present invention is shown in the attached figure. Reference numeral 1 is an excess machine using a floating material, and as the material, granular polystyrene foam having a diameter of about 2 m / m is used. Reference numeral 2 is a precision machine, and the material used is a coil-shaped material capable of capturing suspended matter of about 1 μm. Reference numeral 3 is an ultraviolet sterilizer. That is, the liquid (circulating water) sent to the ultraviolet sterilizer contains suspended matter of about 1 μm,
Compared with those containing suspended matter of μm to 40 μm, the inhibition of ultraviolet rays is greatly improved, and the irradiation efficiency of ultraviolet rays is greatly improved.

る。Conventionally, in this type of pond water overrun and those that circulate and use the liquid like cooling water for cooling towers, because blue particles are generated in the circulating liquid and pathogens harmful to the human body are generated. However, according to the present invention, these problems can be completely eliminated by completely killing them by ultraviolet rays. In addition, the present invention can be easily installed on the rooftop of a building by selecting an over-machine using a lightweight material, and also reduces the burden of a precision over-machine installed in the subsequent stage to prolong the time. It enables continuous operation of. Furthermore, even if the precision machine is clogged, it is a cartridge type, so it is easy to reproduce and replace,
Operation management can be greatly improved compared to the conventional one.
