［産業上の利用分野］
本発明は、サージタンク等の緩衝用貯水槽を用いること
なく、オーバーフロー水をスムースに循環浄化できるよ
うにした循環浄化式用水のオーバーフロー水処理方法に
関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an overflow water treatment system for industrial water using a circulation purification method that enables smooth circulation and purification of overflow water without using a buffer storage tank such as a surge tank. Regarding the method.
［従来の技術］
プールや大浴等において、ろ過、殺菌さらには加熱した
用水をオーバーフローさせてただちに廃棄するのは不経
済であるので、オーバーフロー水を回収し浄化を行って
再利用する循環浄化装置が用いられる。[Prior art] Since it is uneconomical to immediately dispose of overflowing filtered, sterilized, and heated water in swimming pools, public baths, etc., a circulating purification device collects, purifies, and reuses the overflow water. is used.
このオーバーフロー水をスムースに循環ろ過させるため
、従来はサージタンクと呼ばれる緩衝用貯水槽が必ず設
けられている。In order to smoothly circulate and filter this overflow water, a buffer storage tank called a surge tank is conventionally always provided.
これは、一般に、プール等においては、オーバーフロー
水の量が大株者数の変動等に応じて常時変動しているた

ンプが空気を吸い込む等の事態を生じ、スムースな循環
ができないからである。それゆえ、このような、変動を
吸収して安定した循環を可能にするためにサージタンク
等の緩衝用貯水槽が必要であった。This is because, in general, in swimming pools, the amount of overflow water constantly fluctuates depending on changes in the number of large shareholders, etc., so if this overflow water is directly connected to a circulation pump,
This is because the amount of overflow water temporarily significantly exceeds the pump's discharge capacity, or conversely, it becomes less than the discharge capacity and the pump sucks in air, making it impossible to circulate smoothly. Therefore, a buffer storage tank such as a surge tank is required to absorb such fluctuations and enable stable circulation.
［発明が解決しようとする課題］
ところでこの貯水槽の容量は、専門書の指針によれば「

増大を見込むため、さらに大きい設置面積をゼ・要とす
る。[Problem to be solved by the invention] By the way, the capacity of this water tank is ``
In a general pool, the resistance is 20g/rr per pool area, and in a crowded pool it is 40.11/rr? ” is presented. In the 25m x 13m pool of general congestion level,
Applying this guideline and converting, the required capacity of the water tank is 6
．． 5m3, and even if the effective height is estimated to be 1.5m, an installation area of 4rrl' or more is required. If an overflow type is adopted that overflows a certain amount or more at all times, not only when it is crowded, an even larger installation area will be required in order to anticipate an increase in the amount of overflow during use.

化装置の設置面積をより小さくすることが要求される。On the other hand, the main equipment that makes up a circulating purification system, such as filters, pumps, and sterilizers, is not always installed on the floor below the water level of the water reservoir, but rather on the upper floor of a building or, in extreme cases, outdoors. In some cases, it is installed on high ground. In facilities such as swimming pools and bathhouses that are constructed in areas with high land prices, it is required that the installation area of circulation purification devices be made smaller.

法の実施例では、ろ過機の逆洗排出水量より多い新鮮水
が新規に補給されるようになっているものが多いため、
貯水槽内水位が次第に上昇して、保水・緩衝容量が著し
く低下する欠点を持つものも多い。If this request is met and a water storage tank is installed in the design, the water storage tank will occupy a large portion of the limited installation area of the total equipment, so other purification equipment will have to be arranged in three dimensions. There will be constraints that cannot be ignored, such as the loss of data. Furthermore, since the water tank must be installed at a location lower than the water level of the irrigation reservoir, piping and wiring work becomes even more complicated if it has to be installed in a location away from other purification equipment. This has a great impact on architectural design and construction, and puts pressure on the operating area of the equipment. In addition, the diameter of the piping from the overflow drain to the water tank is usually 100 to 1501.
111! 1 is used, and the difficulty in constructing the piping from the left and right spaces of the water reservoir to the water tank installation location increases as the pipe diameter increases. In addition, in many conventional overflow water treatment methods, fresh water is replenished in an amount greater than the amount of water discharged from the filter for backwashing.
Many of them have the disadvantage that the water level in the water tank gradually rises, resulting in a significant drop in water retention and buffering capacity.
また、新築工事に限らず既設のプール等施設の改造に際
しても、該貯水槽の設置場所が確保できない場合があり
、オーバーフロー水回収利用そのものを断念する例も少
なくない。Furthermore, not only in new construction but also in the remodeling of existing facilities such as swimming pools, there are cases where it is not possible to secure a place to install the water tank, and there are many cases where the use of overflow water collection itself is abandoned.
本発明は、上述の背景のもとでなされたものであり、従

水処理方法を提供することを目的としたちのて′ある。The present invention was made against the above-mentioned background, and is a circulation system that enables overflow water to be smoothly circulated and purified without using an M-shock water storage tank such as a surge tank, which was always required in the past. The purpose of this invention is to provide a method for treating overflow water for purifying industrial water.

フロー水を循環することが可能である。[Function] According to the above configuration (1), at least a part of the flow path that directly leads the overflow water to the circulation pump is a water storage pipe having a diameter (nominal diameter) larger than the diameter of the intake port of the circulation pump. If the water level of the water storage pipe is detected and the circulation pump is controlled in accordance with the water level so that a predetermined amount of water is always stored in the water storage pipe, the pump can be removed from the inlet of the circulation pump. It is possible to circulate the overflow water without introducing air into the tank.

た。This fact was first elucidated by the inventor of the present invention as a result of research on fluctuations in the amount of overflow water in various pools and other water reservoirs, as well as piping systems for circulating overflow water. That is, as mentioned above, conventionally, it was common knowledge that in order to smoothly circulate overflow water, it was essential to install a surge tank with a predetermined capacity.

きるか否かの検討の対象外とされていた。Here, in this conventional way of thinking, the capacity of the piping that guides the overflow water to the surge tank was not taken into account. In the conventional thinking, this piping is just a flow path, and therefore, it is usually set to a diameter automatically calculated from the circulation pump's discharge capacity, and is not subject to consideration as to whether it can be used for M teeth. It had been.

能にするということになることが判明した。As a result of various investigations of piping systems in ordinary swimming pools and the like, the present inventor found that the total length of piping that leads overflow water to a surge tank is at least several tens of meters. In addition, as a result of investigating the amount of fluctuation in the amount of overflow water in these various pools, etc., we found that if the diameter of the above-mentioned piping is made slightly larger than the conventional diameter, this piping (water storage pipe)
It has been found that the total capacity and weight of the total length of is sufficient to absorb the above-mentioned fluctuation in the amount of overflow water. In this case, making the diameter of the piping slightly larger means that the diameter of this piping is also made larger than the diameter of the inlet of the circulation pump, and as a result, even if this piping is directly connected to the circulation pump, It turns out that this allows the water stored in the pipes to be used as a buffer while preventing the pump from drawing in air.

水をスムースに循環できるようにしたものである。The present invention has been made by paying attention to such an clarified fact, and detects the water level in this piping (water storage pipe) and controls the circulation pump in accordance with this water level to constantly supply water to the water storage pipe. By storing a predetermined amount of water, overflow water can be smoothly circulated from the inlet of the circulation pump without air being mixed into the pump.

われる。An overflow basin 3 is provided around the pool 1 in which water to be treated 2 is stored, and is configured to receive water overflowing when users enter the pool 1 or the like. This overflow stream 3 is connected to a water storage pipe 4 by a pipe 21, and this water storage pipe 4 is connected to an inlet of a circulation pump 6 by a pipe 22. During normal circulation, the outlet of the circulation pump 6 is connected to the inlet of the filter 10 through the pipe 23, the branch pipe 8, the multi-way valve 9, and the pipe 24, and the outlet of the filter 10 is connected to the inlet of the filter 10 through the pipe 25. , multi-way valve 9, piping 2
6 and piping 27 to the inner side of the pool 1. Therefore, the overflow water overflowing into the overflow pipe 3 is introduced into the water storage pipe 4, and then the circulation pump 6
After passing through the filter 10 and being purified by
The overflow water is returned to the pool 1, and the overflow water is circulated and purified.

理が行われるようになっている。In addition to this circulation purification of the overflow water, a part of the water is introduced from the bottom of the pool 1 to the main circulation purification device through the piping 28, and after being purified, it is introduced into the pool 1 through the piping 29 and 27. The water is then returned to undergo the main circulation purification process.
また、プール１には、これら循環系外からバルブ３０を

なっている。Furthermore, in order to prevent the water in the circulation system from overflowing due to the introduction of fresh water, the pipe 23 connected to the outlet of the circulation pump 6 is branched by a branch pipe 8, and the pipe 23 is connected to the circulation pump 6 through pipes 31 and 32. A portion of the discharged overflow water is discharged outside the system. Note that the pipe 31 is provided with a check valve 33 and a flow control valve 34 to prevent backflow and adjust the discharge amount.
また、ろ過機１０を逆洗する場合は、多方弁９の流路を

ようになっている。In addition, when backwashing the filter 10, the flow path of the multi-way valve 9 is changed to the flow path indicated by the dotted arrow, and the backwash water at that time is discharged to the outside of the system through the pipes 35 and 32. It is supposed to be done.

も循環ポンプ６の吸入口の口径よりは大きいことが必要
である。そうでないと、単に、貯水管４の総延長距離を
長くして容量を多くしても、循環ポンプ４が空気を巻き
込むことになるからである。Now, the water storage pipe 4 described above is laid along the overflow pipe 3, and its diameter is set to be slightly larger than that of conventional piping. The diameter of the water storage pipe 4 is set to an appropriate value depending on the capacity of the pool 1, the amount of overflow water, the total length of the water storage pipe 4, etc.
It is sufficient to provide enough capacity to absorb fluctuations in the amount of overflow water. However, in this case, it needs to be at least larger than the diameter of the suction port of the circulation pump 6. Otherwise, even if the capacity is increased by simply increasing the total length of the water storage pipe 4, the circulation pump 4 will draw in air.
次に、貯水管４の口径を設定する際の具体的条件を説明
する。Next, specific conditions for setting the diameter of the water storage pipe 4 will be explained.
例えば、日本で最も施工例の多い有効容量３５０ｍ３規
模のプールの場合には、プールの平均的オーバーフロー
水量は通常６ｍ３／時間内外である。このため、大株者
の変動その他によるオーバーフロー水の変動を考慮にい
れた場合、緩衝容量としては、６ｍ３内外あれば十分で
ある。For example, in the case of a pool with an effective capacity of 350 m3, which is the most frequently constructed pool in Japan, the average overflow water volume of the pool is usually around 6 m3/hour. Therefore, if fluctuations in overflow water due to changes in large shareholders and other factors are taken into consideration, a buffer capacity of around 6 m3 is sufficient.
ここで、オーバーフロー渭３に沿って敷設される貯水管
の総延長距離は６０ｍ程度となる。したがって、貯水管
４の口径を３００ｍｍとすると、貯水管４の容量として
４．２ｍ３が得られ、貯水管４の口径を４００ｍｍとす
ると、７．５ｍ３の容量が得られる。したがって、貯水
管の口径を３００〜４００ｍｍ以上にすれば必要十分な
緩衝容量が得られることがわかる。これを、プール１の
表面積当たりの口径に換算すると、表面積１ボ当り、貯
水管４の口径が０．７ｍｍ以上となる。すなわち、プー
ル面積が変わってもこの比率で貯水管４の口径を設定す
れば、十分な緩衝容量が得られることになる。Here, the total length of the water storage pipes laid along the overflow bank 3 is about 60 m. Therefore, when the diameter of the water storage pipe 4 is 300 mm, the capacity of the water storage pipe 4 is 4.2 m3, and when the diameter of the water storage pipe 4 is 400 mm, the capacity is 7.5 m3. Therefore, it can be seen that a necessary and sufficient buffer capacity can be obtained by setting the diameter of the water storage pipe to 300 to 400 mm or more. When this is converted into a diameter per surface area of the pool 1, the diameter of the water storage pipe 4 is 0.7 mm or more per surface area. That is, even if the pool area changes, if the diameter of the water storage pipe 4 is set at this ratio, a sufficient buffer capacity can be obtained.
また、プール容量（面積）が大きくなるとオーバーフロ
ー水の量も多くなるが、本実施例の貯水管４では、１時
間当たりのオーバーフロー水の１か、プール１の有効容
量の３％以下であれば、十分な緩衝作用が得られること
が確認されている。Furthermore, as the pool capacity (area) increases, the amount of overflow water also increases, but in the water storage pipe 4 of this embodiment, if the overflow water is 1 per hour or 3% or less of the effective capacity of the pool 1, It has been confirmed that a sufficient buffering effect can be obtained.
それゆえ、循環ポンプ６としては、１時間当たりの吐出
能力が、プール１の有効容量の３％以下であるものを用
いる。Therefore, as the circulation pump 6, one whose discharge capacity per hour is 3% or less of the effective capacity of the pool 1 is used.
次に、貯水管４の水位制御について説明する。Next, water level control of the water storage pipe 4 will be explained.

良い。The water level in the water storage pipe 4 is measured by a water level gauge 5 and sent to a control device 7. In this case, as the water level gauge 5, a strain gauge type or a capacitance type pressure type water level gauge can be used. This pressure type water level gauge determines the water level by measuring the water pressure at the bottom of the water storage pipe 4, and even if a commercially available one is used, the fluctuation in water level of a water storage pipe with the above-mentioned diameter can be reduced by 0.5%. It can be measured with a high degree of accuracy. The output of this water level gauge 5 is sent to the control device 7. Note that it goes without saying that other types of water level gauges may be used as the water level gauge 5. Furthermore, the output signal may be either analog or digital.

ものを用いることも可能となる。The control device 7 receives the measured water level signal sent from the water level gauge 5.
It is compared with a preset reference water level signal, and the circulation pump 6 is controlled based on the comparison result. For example, a signal having an upper limit value and a lower limit value is used as the reference water level signal, and when the measured water level signal exceeds the upper limit value, the circulation pump 6 is driven, and when the measured water level signal falls below the lower limit value, the circulation pump 6 is stopped. Make it. By appropriately setting the upper and lower limits, an appropriate water level can be maintained while reducing the number of times the circulation pump 6 is turned on and off, and stable circulation can be ensured. In this control, even if a simple pump having a constant discharge capacity is used as the circulation pump 6, smooth control without so-called chattering etc. can be performed. In addition to this control method, for example, as the circulation pump 6, the discharge 1
It is also possible to control the discharge amount of this circulation pump so that it is inversely proportional to the measured water level signal by using a pump that can vary the water level. In this case, since the water level of the water storage pipe 4 can be controlled more precisely, the capacity of the water storage pipe 4 can be made smaller, and it is also possible to use one with a smaller diameter.

れている。In addition, in the above-mentioned configuration, the water level of pool 1 at the time of suspension of use (when there are 0 major shareholders) is 5 to 5 times higher than the overflowing water level.
The amount of fresh water to be supplied is adjusted by the valve 30 so that the amount of fresh water is lowered by about 10 mm, and the amount of overflow water discharged to the outside of the system through the branch pipe 8 is adjusted to, for example, a volume of JL 350 m3.
In the case of a pool, the difference between the water level of Pool 1 and the overflow water level can be maintained by adjusting the water level to about 0.5 to 1 m3/hour even if the water level of Pool 1 rises or waves due to the onset of large stocks. Since it is possible to secure a buffer capacity equivalent to , there is a low probability that the water level of overflow tank 3 will match the water level of pool 1 and the overall water level will rise.
It has been confirmed that the surface water of the irrigation water reliably overflows and is introduced into the filter 10, and that coarse spring water and the like floating on the surface layer can be removed at an early stage.

We have confirmed the remarkable effects of reducing the amount of regulators and fungicides used, as well as reducing fuel costs. In addition, since the reference water level in this example can be easily and accurately set using a commercially available digital switch, adjustment work during test runs is easy, and an open water storage tank such as a surge tank is omitted. This has the advantage of avoiding maintenance work such as discharging settled sludge and bad odors from the water tank, and freeing up time to manage the water circulation purification system.

のである。[Effects of the Invention] As described in detail above, the present invention allows overflow water to be guided directly to the circulation pump through a flow path, and at least a portion of this flow path is connected to the diameter of the inlet of the circulation pump. The water storage pipe is configured with a water storage pipe having a larger diameter, and the water level of the water storage pipe is detected and the circulation pump is controlled in accordance with this water level so that a predetermined amount of water is always stored in the water storage pipe. This makes it possible to circulate overflow water from the pump's suction port without introducing air into the pump, thereby eliminating the need for a buffer storage tank such as a surge tank, which was always required in the past. This allows for smooth circulation and purification of overflow water.
