又、薬液を使用した殺菌処理を行なう場合、使用済みの
薬液の処理が面倒で、排水処理施設が大川りなものにな
る事が避けられない。Furthermore, when performing sterilization treatment using a chemical solution, it is difficult to dispose of the used chemical solution, and it is inevitable that the wastewater treatment facility will become a large river.
本発明の殺菌洗浄方法は、上述の様な不都合を何れも解
消するものである。The sterilization cleaning method of the present invention eliminates all of the above-mentioned disadvantages.

時に行なう。In addition, in the case of the invention described in claim 2, the ozonated water is not discharged from the treatment 4M, but the detergent is injected into this treatment tank, and the ozonated water is heated to a temperature of 40°C or less, and the ozone Water and detergent (not necessarily alkaline detergent) are subjected to ultrasonic vibration to simultaneously decompose ozone and clean the object to be cleaned.
(作 用)

ない。(Function) When the sterilizing cleaning method of the present invention configured as described above is carried out, bacteria attached to the object to be cleaned are sterilized at the stage of being immersed in ozonated water. Since the object is not heated, blood adhering to the object to be cleaned will not coagulate, and blood will not be difficult to remove during subsequent cleaning operations.

に在留する液体は、単なるアルカリ洗剤水溶液となる。In the case of the invention described in claim 1, after the sterilization treatment, an alkaline detergent is added to the ozonated water used for the sterilization treatment, and the cleaning operation is further performed by applying ultrasonic waves, but the ozone is quickly decomposed by the alkali. Moreover, since it is also decomposed by mechanical vibration, the ozone contained in ozone water is almost completely decomposed during the cleaning process, and the liquid remaining in the treatment tank after the cleaning process is completed becomes just an alkaline detergent aqueous solution. .
単なるアルカリ洗剤水溶液の処理は、通常の排水処理と
同様、簡単な処理装置で行なえる。Treatment of a simple aqueous alkaline detergent solution can be carried out using simple treatment equipment, similar to ordinary wastewater treatment.

ち難くなる事はない。In addition, in the case of the invention described in claim 2, after sterilization treatment,
The ozonated water used for sterilization is heated to a temperature of 40°C or less, detergent is added to this ozonated water, and ultrasonic waves are applied for cleaning. The ozone contained in the ozone water is almost completely decomposed during the cleaning process, and the liquid remaining in the treatment tank after the cleaning process is completed becomes just a detergent aqueous solution and cannot be treated as normal wastewater treatment. Similarly, it can be done with a simple processing device. At temperatures below 40° C., blood and the like adhering to the object to be cleaned will not coagulate and become difficult to fall off the surface of the object to be cleaned.
尚、オゾン水中からのオゾンの脱気をより迅速に行なう
