摘要： PURPOSE:To easily clean the fouling of a jacket and to effectively increase the transparency of water by, passing water to be treated through a filler medium before passing it outside the jacket in water purification and by, raising a net body to bring the filter medium into contact with the jacket, to clean the jacket in backwashing. CONSTITUTION:The proper number of jackets 4 in each of which a ultraviolet ray source is installed are arranged inside a water treating device body 1, and a net body 6 is provided at a place under the jackets, and a lot of filter media 7 are arranged below the net body 6 closed up together. In water cleaning, after water to be treated is put in from an injection port 2 for water to be treated and passed through the filter medium, it is passed through a housing part of the jackets 4 to treat it. In backwashing in which the surface of the jackets are cleaned, the net body 6 is raised to near the upper end of the jackets 4 to bring the filter medium 7 into contact with the jackets 6, and air is jetted from a backwash pipe 10 to agitate the filter medium 7, allowing the filter medium 7 to come into contact with the surface of the jackets 4.

摘要： PURPOSE:To maintain the life of ultraviolet ray sterilizing lamp and to treat the whole water to be treated efficiently and uniformly by providing jetting openings of water to be treated and ozone between plural rows of ultraviolet ray sterilizing lamps, providing a filtration vessel in which filter medium is piled up, and circulating the water to be treated and ozone by a pump. CONSTITUTION:Numbers of ultraviolet ray sterilizing lamps 3 are disposed in plural rows with a specified distance between rows, and jetting openings of water to be treated and ozone are provided between them, so that water is difficult to reach jackets 2 and ultraviolet ray sterilizing lamps 3 even when the water is vigorously jetted, so that the vibration of ultraviolet ray sterilizing lamps 3 is small and the life of ultraviolet ray sterilizing lamp 3 is maintained and the damage on the jackets 2 is eliminated. As the water contg. ozone is strongly energized, the whole water to be treated is efficiently and uniformly treated. The dust in the water is physically removed by the filter medium 7, and the noise transmitted to the outside is small because a pump 5 is situated in the water.

摘要： PURPOSE:To conduct a leakage current in water inside a water purifying device to the exterior of the device and thereby prevent electric shock accident by providing upper and lower electric leakage prevention elements outside an ultraviolet sterilization lamp and overlapping partly the tips of these electric leakage prevention elements at a fixed interval. CONSTITUTION:An upper electric leakage prevention element 23 is provided outside a submerged ultraviolet sterilization lamp 19 in such a manner that the upper part of the former protrudes above the water level and the lower part is located halfway through the depth of the water. In addition, a lower electric leakage prevention element 24 is provided halfway through the water upward from the bottom of a water purifying device. Then tips of these upper and lower electric leakage prevention elements are vertically overlapped partly over each other. If the vertical flow of water in the body of the device 11 changes or an electric current leaks into water from the feeder part of the sterilization lamp 19 due to the damage of a water-cooling jacket 18 and the sterilization lamp, this leakage current is conducted to the exterior of the body of the device 11 by means of the upper and lower current leakage prevention elements 23, 24 and an earth wire 25. Thus electric shock accident can be prevented.

摘要： PURPOSE:To conduct a current leaking into water inside the body of a water purifying deice from the feeder part of an ultraviolet sterilization lamp, to an area outside the purifying device and thereby prevent an electric shock accident by providing a conductive electric leakage prevention element which covers a submersible ultraviolet sterilization lamp on the lower surface of a supporting plate. CONSTITUTION:A conductive electric leakage prevention element 23 covering an ultraviolet sterilization lamp 19 is provided on the lower surface of a supporting plate 11. This electric leakage prevention element 23 is formed with a conductive reticulate body of at least, 10-mesh size. If a water-cooling jacket 18 and the ultraviolet sterilization lamp 19 on a water purifying device with the electric leakage prevention element 23 are damaged by an external impact and the current leaks into water from the feeder part of the lamp 19, the current is conducted to an area outside the water purifying device through the electric leakage prevention element 23. Consequently, an electric shock accident in a park pond can be prevented to protect fish against fatal electric shock.

摘要： PURPOSE:To conduct a leakage current into water provided in the body of a purifying device from a feeder part of an ultraviolet sterilization lamp, to the outside of the purifying device through a current leakage preventing element to prevent an electric shock accident by covering an inlet port and an outlet port in the body of the purifying device with a conductive current leakage preventing element. CONSTITUTION:A submersible ultraviolet sterilization lamp is provided in the interior of a box-type water purifying device. The inlet port 12 and outlet port 13 of the purifying device are covered with conductive leakage prevention elements 25, 26. Consequently, even if a water-cooled jacket and the sterilization lamp in the body of the purifying device 11 are damaged by an external impact and an electric current leaks into the body of the purifying device from the feeder part of the sterilization lamp, this leakage current is conducted to the exterior of the body of the purifying device 11 through the current leakage prevention bodies 25, 26 and earthing wire 27 provided on the inlet port 12 and outlet port 13 of the purifying device. As a result, the occurrence of electric shock accident in a park pond can be prevented and fish be protected against fatal electric shock.
