摘要： PURPOSE:To eliminate the need for chemicals and to remove refuse floated in water and to prevent generation of water bloom by constituting the purifier so that water in a filter tank naturally flows to a tank housing a sterilizing lamp and one part of the treated water is directly returned to the filter tank and also the residual water is circulated and reintroduced into the filter tank. CONSTITUTION:Water to be treated naturally falls to the inside of a filter tank 1 from a water passing net and suspended matter contained in the water is filtered. The water in the filter tank 1 naturally flows to a tank 6 housing sterilizing lamps by water pressure. Water bloom is killed by ultraviolet rays emitted from the sterilizing lamps 7 and organic substance contained in the water is decomposed and removed. Since one part of the treated water is directly returned to the filter tank by a storage pump 9, filter treatment is more severely performed and activated water is allowed to react with impurities in the filter tank and purification of water quality is more promoted.

摘要： PURPOSE:To easily remove the suspended matter accumulated on filter media so that secondary chemical pollution is prevented and carcinogens are decomposed away by bringing ozone into contact with the treated water passing a sterilizing lamp housing tank to flocculate the particles of the suspended matter in the water, then adsorbing the suspended matter flocculated after passing the filter media in a filter medium housing tank by the filter media. CONSTITUTION:The ozone generated from the sterilizing lamp 2 or the ozone sent from a noiseless discharge type ozonizer comes into contact with the treated water passing the sterilizing lamp housing tank 1 to flocculate the particles of the suspended matter in the water. The pathogenic bacteria in the water are sterilized and the org. matter is photooxidation-decomposed, by which COD, BOD and odorous components are decreased. The treated water thereafter passes the filter media 8 of the filter medium housing tank 6 where the flocculated and suspended matter is adsorbed by the filter media 8. The filter media 8 is suspended in the water in the filter medium housing tank 6 and is agitated in the case of back washing the filter media 8. The dust, etc., sticking to the filter media are thereby separated and easily removed.

摘要： PURPOSE:To eliminate the need for chemicals and to remove refuse floating in water and to prevent generation of water bloom by purifying water with both a filter medium and an ultraviolet sterilizing lamp and assembling the filter medium to one part of a filter tank during water treatment and floating the assembled filter medium in water at a time of backwash and separating attracted suspended matter from the filter medium. CONSTITUTION:Water to be treated is introduced into the inside of a filter tank 1 from a water passing net 2 and suspended matter contained in water is filtered. The water in the filter tank 1 is introduced into a tank 7 for housing the sterilizing lamps. Water bloom is killed by ultraviolet rays emitted from the sterilizing lamps 8 and organic substance contained in water is decomposed and removed. Further at a time of backwash, the filter medium 3 is strongly and forcedly floated in water by both liquid supplied through the water feed nozzles 11 and gas sent from a diffusing cylinder 12. Suspended matter attracted to the filter medium 3 is effectively separated and discharged to the outside. Filtering function is excellently reexhibited.

摘要： PURPOSE:To easily remove the suspended matter accumulated on filter media so that secondary chemical pollution is prevented and carcinogens are decomposed away by constituting the device in such a manner that ozone is brought into contact with the suspended matter remaining in the treated water produced after passing through the filter media and the flocculated and suspended matter circulates together with the water and pass through the filter media by which the suspended matter is adsorbed on the filter media. CONSTITUTION:The suspended matter gathers closely in the bottom in a filter medium housing tank 1 and is physically filtered by the filter media 3 while the water is subjected to the cleaning treatment in the above-mentioned filter medium housing tank. The pathogenic bacteria in the treated water are sterilized by the UV rays from a lamp 11 and the ozone, by which the org. matter is photooxidation-decomposed and COD and BOD as well as odorous components are decreased. Further, the ozone comes into contact with the the suspended matter of small particles passed the filter media and the suspended matter is converted to inorg. matter or flocculated. The suspended matter is adsorbed by the filter media at the time when the suspended matter circulates and passes again the filter media. The cleaning effect is thus progressed and the water is additionally cleaned. The filter media 3 is suspended and agitated in the water in the filter medium housing tank 1 in the case of back washing the filter media 3. The dust, etc., sticking to the filter media 3 are thus easily separated and removed.

摘要： PURPOSE:To clarify sewage at a high speed, by aerating the sewage with oxygen-containing gas in a biological reaction tank and recirculating the aerated sewage to the other part in the biological reaction tank through a recirculation flow passage. CONSTITUTION:The biological reaction water discharged from a biological reaction tank 1 is recirculated to the other part in the biological reaction tank 1 through the recirculation flow passage consisting of a take-out recirculation pipeline 2, the inlet chamber 5 in a solid-liquid separation apparatus 3 and a return recirculation pipeline 6, and the reaction of aerobic bacteria with the sewage is performed in the aerobic part 10 in the biological reaction tank 1. Subsequently, the reaction liquid in the aerobic part 10 passes through a communication part 8 to flow in the anaerobic part 11 in the biological reaction tank 1 to perform the reaction of anaerobic bacteria with the sewage. The liquid flowing through the recirculation flow passage is filtered by a porous membrane 4 to return the filter residue to the upper part of the biological reaction tank 1. By this method, filtering can be continuously performed over a long period of time.

摘要： PURPOSE:To maintain a filtration capacity for a long period of time by providing the space allowing the fiber lumps stuck with more than a specified amount of solids to float or to sink when the fiber lumps in the lower layer of a fiber lump filter layer are stuck with fine solids contained in the upward water flow in the filtration. CONSTITUTION:A water flow opening part 4 is provided between an upstream side weir 2 built in a water passage 1 and the bottom part 3 of the water passage, and an overflow part is provided on the upper part of the downstream side weir 5 built in the downstream side of the upstream side weir 2 in the water passage 1. And, an upper perforated plate 6 to receive the fiber lumps and a lower perforated plate 7 to receive the fiber lumps are respectively disposed in the water between the upstream side weir 2 and the downstream side weir 5. Under the perforated plate 6, the fiber lump filter layer 9 consisting of many fiber lumps 8 floated by the upward water flow is formed and the space 10 allowing the fiber lumps to float or to sink is provided between the filter layer 9 and the perforated plate 7. As a result, the filtration capacity of the filter layer consisting of a lot of fiber lumps is kept in a high capacity for a long period of time, and the pressure loss of water flow is kept in a low value.
