The figure is a flow diagram showing a pool water purifying apparatus according to an embodiment of the present invention. The same parts as those in FIG. 10 is a connection pipe P 3 between the circulation pump 4 and the filter 5 (a part of the pool water circulation path)
The branch pipe P 6 a via and connected flow regulating valve, 11 is a flow meter which is connected via the branch pipe P 7 in the flow regulating valve 10, 12 via the branch pipe P 8 in the flow meter 11 In the activated carbon tank to which the inlet side is connected, a part of the discharge water (circulation pool water) of the circulation pump 4 is branched and introduced through the branch pipes P 6 and P 7 , and the pollutants contained in the divided pool water are activated carbon. Oxidative decomposition treatment of the pollutant is performed by the biological layer adsorbed on the layer and formed on the activated carbon layer. 13 is an ejector for injecting ozone, which is connected to the outlet side of the activated carbon tank 12 through a branch pipe P 9 , and 14 is an ozone generator that supplies ozone to this ejector 13.
By supplying ozone to the ejector 13 from the ejector 13, the ejector 13 sucks in the ozonized gas and injects it into the split pool water from the activated carbon tank 12, and the split pool water and ozone are oxidized and decomposed. Let 15 is connected to the ejector 13 on the inlet side via a branch pipe P 10 , and on the outlet side is connected to the suction side of the circulation pump 4 by the branch pipe P 11 (that is, the inlet branch point P of the branch pipe P 6).
This is a gas-liquid separation tank connected to the pipe P 2 of the pool water circulation path on the upstream side of O), and this gas-liquid separation tank 15 separates ozone and air that have not reacted with the split pool water. Reference numeral 16 is an air vent valve for discharging the air separated in the gas-liquid separation tank 15 to the outside, and 17 is an ozone decomposing tower connected to the gas-liquid separation tank 15 via the air vent valve 16. The reaction ozone is decomposed and discharged as oxygen to the outside. In the above, each of the branch pipes P 6 to P 11 is branched from the discharge side pipe P 3 of the circulation pump 4 in the pool water circulation path, and a part of the circulation pool water by the discharge of the circulation pump 4 is diverted. A branch circulation return path for returning the split pool water to the suction side of the circulation pump 4 in the pool water circulation path via the flow rate adjusting valve 10, the flow meter 11, the ejector 13, and the gas-liquid separation tank 15, respectively. I am configuring. Next, the operation will be described. When the circulation pump 4 is operated, the pool water 2 in the pool water tank 1 polluted by swimmers circulates through the pool water circulation path (each pipe P 1 to P 5 ). A part of the circulating pool water 2 discharged from the discharge side pipe P 3 flows into the branch pipe P 6 , and the divided pool water flows into the activated carbon tank 12 via the flow rate adjusting valve 10 and the flow meter 11. . Then, in the activated carbon tank 12, the pollutants of the inflowing split pool water are adsorbed by the activated carbon layer, and the biological layer formed in the activated carbon layer oxidizes and decomposes the pollutants. Next, ozone generated by the ozone generator 14 is sucked by the ejector 13 and injected into the treated water (split pool water) flowing out of the activated carbon tank 12. As a result, the ozone and the split pool water undergo an oxidative decomposition reaction. Then, the split pool water flows into the gas-liquid separation tank 15. In the gas-liquid separation tank 15, when the reacted ozone is seen, a part thereof undergoes an oxidative decomposition reaction with the diverted pool water, a part becomes so-called ozone water dissolved in the diverted pool water, and a part thereof is not yet formed. Becomes reaction ozonized gas,
The unreacted ozonized gas flows into the ozone decomposing tower 17 through the air vent valve 16, and the ozone decomposing tower 17 decomposes ozone and discharges it as oxygen. On the other hand, the ozone water is returned from the gas-liquid separation tank 15 to the suction side pipe P 2 of the circulation pump 4 through the branch pipe P 11 . As a result, the circulating pool water passing through the suction side pipe P 2 (pool water circulation path) and the returned ozone water from the branch pipe P 11 are mixed. Therefore, the entire amount of the circulating pool water is oxidized by the returned ozone water. The ozone here sterilizes and decolorizes the circulating pool water, decomposes organic substances, partially dissociates it, and increases the amount of dissolved oxygen in the circulating pool water. Then, the circulating pool water in this state (that is, the state where the amount of dissolved oxygen is high) is discharged by the circulating pump 4, a part of the circulating pool water is branched again to the branch pipe P 6 , and the flow rate adjusting valve 10, It flows into the activated carbon tank 12 through the branch pipe P 7 , the flow meter 11, and the branch pipe P 8 . Therefore, in the activated carbon tank 12, the breeding of organisms is promoted by the shunt pool water having a high dissolved oxygen content, and the soluble organic substances partially dissociated by ozone in the shunt pool water are oxidized by the organisms. It becomes easy to decompose and its oxidative decomposition is promoted. By repeating the above cycle, pollutants of pool water are efficiently and continuously removed. In the above embodiment, a part of the circulating pool water is branched by the discharge pressure of the circulation pump 4 in the pool water circulation path to the branch pipe P 6.
Although so as to branch circulated back to the suction side of the circulating pump 4, the provided water pump 18 for branch circulation back to the branch pipe P 6, thereby, the circulating pump 4 part of the circulating pool water It may be returned to the suction side. FIG. 2 shows another embodiment of the present invention. In this embodiment, an inlet branch point PO of the branch pipe P 6 is connected to the pipe P 4 between the filter 5 and the warmer 6 in the pool water circulation path, and the branch pipe is provided on the upstream side of the inlet branch point PO. The branch pipe P 11 on the outlet side is connected to P 4 , and the other configurations are the same as in the previous embodiment. Therefore, a part of the pool water is diverted from the pool water circulation path to the branch circulation return path, and the return point of the ozone mixed water purified by the branch circulation return path is the suction side of the circulation pump 4 as in the previous embodiment. However, the present invention is not limited to this, as long as it is on the upstream side of the inlet branch point PO, and in this case, the same operational effect as the previous embodiment is obtained.

ンパクトになり、安価に得られるなどの効果がある。As described above, according to the present invention, the branched circulation return route is branched from the pool water circulation route, the activated carbon tank and the ozone supply means located on the downstream side of the activated carbon tank are provided in the branched circulation return path, and the activated carbon is activated. Ozone is injected into the split pool water that has passed through the tank by the ozone supply means, thereby returning the split pool water as ozone water to the pool water circulation path on the upstream side from the inlet branch point of the branch circulation return path. Therefore, the biological oxidation in the activated carbon tank by ozone is promoted, and the oxidative decomposition removal treatment of the pollutants of pool water that cannot be decomposed by the ozone alone treatment can be performed efficiently.
Since the processing is performed by the branch circulation return route, the entire apparatus is compact and can be obtained at low cost.
