菌ユニットに関する。Detailed Description of the Invention [Industrial Application Fields] The present invention aggregates and filters fine pollutant components contained in bath water, backwashes the pollutants accumulated on the filter medium, and further performs ozone sterilization treatment. This invention relates to a bath water circulation purification and sterilization unit that sterilizes bacteria using a device and maintains the quality of bath water stably over a long period of time.
［従来の技術］
一般に、浴水の濾過は急速砂濾過によって行なわれてい
ることが多い。またこの場合、カートリッジフィルター
を併用する濾過方法も知られている。[Prior Art] Generally, bath water is often filtered by rapid sand filtration. In this case, a filtration method that uses a cartridge filter is also known.
一方、浴水中の細菌類の滅菌方法としては、次亜塩素酸

、オゾン反応槽を備えた例として、浄水場、下水処理場
、プール浄化装置等が知られている。On the other hand, as a method for sterilizing bacteria in bath water, in addition to the widely used method of injecting chlorine-based chemicals such as sodium hypochlorite, methods using ultraviolet light are also known. Furthermore, ozone is also used, and in many cases, ozone is directly injected into the bathtub. Moreover, water purification plants, sewage treatment plants, pool purification devices, etc. are known as examples equipped with ozone reaction tanks.
［発明が解決しようとする課題］
しかしながら、上記した従来の方法にあっては、以下に
述べるように多くの問題か存在する。[Problems to be Solved by the Invention] However, the conventional method described above has many problems as described below.
すなわち、急速砂濾過法では、水中の微細な汚れを除去
するため、硫酸バンド等の凝集剤、ポリ塩化アルミニウ

この方法では濾材の表面に汚濁物が集積して濾過性能が
低下するのて、これを除去する必要かある。また、カー
トリッジフィルターを併用した場合には、フィルター交
換か必要となり、長時間の連続運転が困難となる。In other words, in the rapid sand filtration method, in order to remove fine dirt in the water, pretreatment for floc formation is required, which involves adding a flocculant such as sulfuric acid bandate, a flocculation aid such as polyaluminum chloride, etc. The processing process becomes complicated. Also,
In this method, contaminants accumulate on the surface of the filter medium and the filtration performance deteriorates, so it is necessary to remove the contaminants. Furthermore, if a cartridge filter is used together, the filter must be replaced, making long-term continuous operation difficult.
次亜塩素酸ナトリウムなどの塩素系薬剤を使用する場合
には、浴水中の残留塩素が通常０．２〜０．５ｐｐｍ程
あり、塩素臭が問題となることが多い、さらに、有害な
塩素系有機化合物か生成する場合もある。When using chlorine-based chemicals such as sodium hypochlorite, the residual chlorine in the bath water is usually about 0.2 to 0.5 ppm, and the odor of chlorine often becomes a problem. Organic compounds may also be produced.
紫外線を利用する方法では、滅菌が主体であり、フロッ
ク形成効果は余り期待することができない。In the method using ultraviolet rays, sterilization is the main purpose, and the floc-forming effect cannot be expected to be very effective.
オゾンを利用する方法では、オゾンを浴槽に直接注入す
ると環境基準（０，ｌｐｐｍ以下）を超える心配かある
。In the method of using ozone, if ozone is injected directly into the bathtub, there is a risk of exceeding environmental standards (0.1 ppm or less).
さらに浄水場、下水処理場、プール浄化装置等ては濾水
をオゾン処理しているため濾過槽の負荷が大きくなる。Furthermore, in water purification plants, sewage treatment plants, pool purification systems, etc., filtrate is treated with ozone, which increases the load on the filtration tank.
