次に、本実施の形態の第一浄水システム１の使用方法及びその作用について、図１及び図２を参照しながら説明する。ここで、図中の矢印は水の流れを示している。 Next, the usage method of the 1st water purification system 1 of this Embodiment and its effect | action are demonstrated, referring FIG.1 and FIG.2. Here, the arrows in the figure indicate the flow of water.
図１は、第一浄水システム１の平常時における使用態様を示している。平常時は、第一浄水システム１外から市水２が供給されているため、備蓄水槽４１から貯水槽５に備蓄水を供給する必要がない。 FIG. 1 shows a usage mode of the first water purification system 1 in a normal state. In normal times, city water 2 is supplied from outside the first water purification system 1, so that it is not necessary to supply the stored water from the stored water tank 41 to the water tank 5.
そこで、平常時には第一切替手段４２を閉塞し、一般的に市水に比して雑菌が多い風呂水等の家庭内の備蓄水を貯水槽５に供給しない。 Therefore, the first switching means 42 is closed during normal times, and domestic stored water such as bath water, which generally contains more germs than city water, is not supplied to the water tank 5.
建物内で市水２を浄化する毎に、貯水槽５に浄水装置３で分離された濃縮水や雨水が貯水されていくため、雨が長期間降らない場合でも貯水槽５には常に濃縮水が貯水されており、使用に供することができる。 Every time the city water 2 is purified in the building, the concentrated water or rainwater separated by the water purification device 3 is stored in the water tank 5, so that even if it does not rain for a long time, the water is always stored in the water tank 5. Is stored and can be used.
また、平常時は、市水２由来の塩素により、貯水槽５内が清浄に保たれている。濃縮水には浄水装置３で浄水から取り除かれた塩素が高濃度に含まれ、貯水槽５内が除菌されるから、貯水中の雑菌の繁殖が防止できる。 Moreover, in the normal time, the inside of the water tank 5 is kept clean by the chlorine derived from the city water 2. The concentrated water contains a high concentration of chlorine removed from the purified water by the water purification device 3 and the inside of the water storage tank 5 is sterilized, so that the propagation of germs in the stored water can be prevented.
すなわち、市水２に含まれていた塩素は浄水装置３で浄化水から除去され、濃縮水側に濃縮されるから、貯水槽５中の塩素濃度は市水２中より高濃度である。 That is, the chlorine contained in the city water 2 is removed from the purified water by the water purification device 3 and concentrated on the concentrated water side, so that the chlorine concentration in the water tank 5 is higher than that in the city water 2.
原水を上水として建物内に供給している場合であっても、水道から供給されている場合には水道法施行令に定められた残留塩素濃度を保持している。 Even when raw water is supplied into the building as clean water, the residual chlorine concentration stipulated in the Ordinance for Enforcement of the Water Supply Law is maintained when it is supplied from the water supply.
それゆえ、原水を被処理水として利用した場合でも、市水２の場合と同様、貯水槽５中の塩素濃度は市水中より高濃度であり、水の汚染防止効果がある。 Therefore, even when raw water is used as treated water, the chlorine concentration in the water storage tank 5 is higher than that in the city water, as in the case of the city water 2, and there is an effect of preventing water contamination.
貯水槽５内の濃縮水は、貯水槽５に設けた蛇口・水栓等から必要な時に取り出して、洗車・散水等、高品質な浄化水が要求されない場面での利用に供される。 The concentrated water in the water storage tank 5 is taken out from a faucet, faucet and the like provided in the water storage tank 5 when necessary, and is used in situations where high-quality purified water is not required, such as car washing or watering.
貯水槽５に貯水された水を掃除・洗濯・風呂・掃除の用に供する場合には、貯水槽５と適宜の場所を接続する流路を設けたり、ポンプを設置する等、水の汲み上げや加圧送水にも対応可能である。 When the water stored in the water storage tank 5 is used for cleaning, washing, bathing or cleaning, a water flow path connecting the water storage tank 5 to an appropriate place or a pump is installed. Applicable to pressurized water supply.
また、平常時は水を再利用する必要がないから、第二切替手段５１を閉塞しておく。 Further, since it is not necessary to reuse water during normal times, the second switching means 51 is closed.
浄水装置３により市水２から分離された浄化水は、浄化水流路３１１を介して浄化水使用域４に供給され、例えば調理場、浴室又は洗面所などにおいて、飲食、炊事、入浴・シャワーなど、日常生活の用に供される。 The purified water separated from the city water 2 by the water purification apparatus 3 is supplied to the purified water use area 4 through the purified water flow path 311. For example, eating, drinking, cooking, bathing / shower, etc. in a kitchen, bathroom or washroom, etc. Served for everyday life.
次に、図２は、第一浄水システム１の非常時における使用態様を示している。災害が発生したような非常時で第一浄水システム１外からの市水２の供給が停止した場合には、システム内から被処理水を供給する。すなわち、平時と非常時とでは、被処理水が異なる。 Next, FIG. 2 shows a usage mode of the first water purification system 1 in an emergency. When the supply of city water 2 from the outside of the first water purification system 1 is stopped in an emergency such as a disaster has occurred, treated water is supplied from within the system. That is, the water to be treated is different between normal and emergency.
具体的には、非常時には第二切替手段５１を開放し、第一浄水システム１内の貯水槽５から貯水流路５１１を介して、浄水装置３に被処理水を供給する。 Specifically, in an emergency, the second switching means 51 is opened, and the water to be treated is supplied from the water storage tank 5 in the first water purification system 1 to the water purification apparatus 3 via the water storage channel 511.
さらに、第一切替手段４２を開放し、建物内の備蓄水槽４１から備蓄水流路４１１を介して、貯水槽５に水を供給する。 Furthermore, the 1st switching means 42 is open | released and water is supplied to the water storage tank 5 through the stockpiling water flow path 411 from the stockpiling water tank 41 in a building.
非常時に第一浄水システム１を使用することにより、システム外からの市水２の供給が断絶した場合にも、濃縮水や建物内の備蓄水を回収、浄化、再利用して、飲食用水及び生活用水を確保することができる。 Even when the supply of city water 2 from outside the system is cut off by using the first water purification system 1 in an emergency, the concentrated water and the stored water in the building are collected, purified, and reused, Water for daily use can be secured.
第一浄水システム１は、平常時にも非常時にも高品質の浄化水を得ることを可能にするシステムである。 The first water purification system 1 is a system that makes it possible to obtain high-quality purified water during normal times and emergencies.
また、特に図２に示した非常時においては、浄水装置３で備蓄水など市水２よりも雑菌等が多い水を浄化することになる。 In particular, in the emergency shown in FIG. 2, the water purifier 3 purifies water that contains more germs and the like than the city water 2 such as reserve water.
飲食の用に供することのできるレベルの浄化水を得るためには、平常時よりポンプ３２の出力を上げ、より高い圧力を膜３１にかけることが必要となる。更に、膜３１を複数枚、複数種類、または平常時に比して頻繁に交換する等の対応も可能である。 In order to obtain purified water at a level that can be used for eating and drinking, it is necessary to increase the output of the pump 32 and apply a higher pressure to the membrane 31 than usual. Further, it is possible to cope with a plurality of membranes 31, a plurality of types, or frequent replacement as compared with normal times.
以下、前記した実施の形態とは別の形態の実施例について、図３を参照しながら説明する。なお、前記実施の形態で説明した内容と同一乃至均等な部分の説明については、同一用語又は同一符号を付して説明する。 Hereinafter, an example of a mode different from the above-described embodiment will be described with reference to FIG.
