摘要： PURPOSE:To remove slime in a water pipe with an optimum ozone aq. soln. minimized in metallic corrosion by regulating the flow rate in a water pipe system in accordance with the material of the water pipe. CONSTITUTION:When a valve 13 is closed and valves 11, 12, 15 are opened, water in a water tank 6 is sent to an ozone absorption tower 2 with a pump 9. Ozone is absorbed herein and the obtained ozone aq. soln. is sent to a water pipe system 4 through the valve 12 with a pump 10. Further since the valve 15 is opened, the ozone aq. soln. is separated into a heat exchanger 3 and a by-pass pipeline 21. It is passed through a plant pipeline 5 and returned to the water tank 6. Thereby slime in the water pipe systems 4, 5 and the heat exchanger 3 is removed. In this case, the pump 10 is selected to the volume capable of being pressurized and introduced at several atmospheres. In such a way, even when slime is present in the water pipe systems 4, 5, the flow velocity of the ozone aq. soln. is made high and the removal capacity of the ozone aq. soln. is held constant in the water pipe. Thus, slime is efficiently and uniformly removed.

摘要： PURPOSE:To make sewage as high quality treated water by adding a catalyst to an effluent of a secondary treatment process from a sewage treatment facility, recovering the catalyst while treating the effluent with ozone, and filtering the resulting effluent after adding a flocculant. CONSTITUTION:Flowing water to be treated is led to the secondary treatment process 8 such as an activated sludge process, and a suspension catalyst (e.g. iron oxide catalyst) 9 is added to the treated water flowing out from the secondary treatment process. Then, it is led to ozone treatment process 10 and while carring out the ozone treatment, the suspension catalyst 9 is recovered and recycled. Further, after a flocculant 11 is added to the ozone treated water flowing out from the ozone treatment process 10 and adding a trace of the suspension catalyst 9, treated water is obtained through a sand filtration process 12. Periodically cleaned water in the sand filtration process 12 is sent to a sludge treating process 13.

摘要： PURPOSE:To uniform the temperature in an ozone degradation column, prevent active carbon from getting deteriorated because of local heating and prevent ozone degradation performance from getting lowered because of local deterioration by providing a heat transfer material to transfer the heat to an outer periphery of a column in a central section of the ozone degradation column constituted of an active carbon layer. CONSTITUTION:A heat transfer material 4 constituted of a stainless material with ozone oxidation resistance or the like is provided horizontally in the middle of an active carbon layer 5 of an ozone degradation column 1 to decompose the ozone in gas. The heat transfer material 4 can act as a diffusion plate for the gas flow in a central section of an ozone degradation column and also can uniform the heat of the active carbon layer in order to transfer and diffuse the heat to an outer periphery, which uniforms the consumption of active carbon and eliminates sinter consumption of active carbon generated by oxygen and offer an economical way of consumption.

摘要： PURPOSE:To efficiently subject waste liquid to filtering treatment, by connecting the feeder of an oxidizer for feeding ozone-contg. gas into waste liquid with a pipeline system. CONSTITUTION:Waste liquid is transferred through a feed pipe 10 thereof with a feed pump 9 and sent into a vessel 4. On the other hand, oxygen or air is sent to an ozonizer 7 from a gas feed source 8 and made to ozone-contg. gas and thereafter fed into the vessel 4. After the waste liquid sent into the vessel 4 is brought into contact with ozone-contg. gas bubbled through a diffuser 5, it is transferred through a discharge pipe 12 of the waste liquid with a feed pump 11 thereof, and sent to a hollow yarn membrane filter 2 and filtered. Ozone-contg. gas is made harmless by decomposing ozone with a decomposition tower 13 of ozone and thereafter discarded. Thereby the load of the title equipment can be reduced.

The raw water supply pipe 5 and the backwashing liq. discharge pipe 9 are then closed, ozonized air generated in an ozonizer 10 is introduced into a diffusion pipe 12 through an ozonized air supply pipe 11 and injected to the part B of a filter vessel 1 as tiny bubbles, the ozone is brought into contact with the hollow yarn membrane 2 from its outside, and the sticky material due to microbes, metal oxides, etc., are oxidized and released. The ozonized air accumulated at the part B of the filter vessel 1 is discharged from an exhaust gas discharge pipe 13 through an ozone decomposing tower 14.

摘要： PURPOSE:To reliably prevent gas leakage so as to increase the life of a fuel cell by improving the elasticity and the contact between the end section of the rib electrode and the gas-separating plate by interposing between them a layer of kneaded sealing material containing a thermoresistant electrolyte-resistant fluorine resin powder. CONSTITUTION:A layer of a kneaded sealing material 6 composed of 40-60wt% a thermoresistant electrolyte-resistant fluorine resin powder, 60-40wt% fluorine oil and 1.5-4wt% a silicon carbide powder is interposed between the end section of a rib electrode 2 and a gas-separating plate 3. It is formed according to the following procedure during assembly of a fuel cell. After a fluorine resin film 4 is stuck to the end section of each rib electrode 2 having a matrix, the kneaded sealing material 6 is extruded upon the film 4 and then is rolled using a small roller. After that, a gas-separating plate 3 is placed over the material 6 and then a downward pressure is applied to the plate 3 to bring the rib electrode 2 and the plate 3 into close contact with each other. Due to the sealing material layer, the elasticity and the contact between the rib electrode 2 and the gas-separating plate 3 are improved and therefore no gas leaks from between the electrode 2 and the plate 3 even after repeated cycles of heating and cooling. Consequently, it is possible to produce a fuel cell with a remarkably long life.

摘要： PURPOSE:To prevent the cohesion and coarseness of platinum colloid particles and obtain catalyst with a long life by supporting the platinum colloid particles on the surface of carbon particles and allowing them to touch ozone in suspension status or powder-type floating status. CONSTITUTION:Ultrasonic treatment is performed by suspending and mixing carbon particles in a hexachloroplatinic acid solution and applying a sodium formate solution to the said solution while irradiating both solutions with ultrasonic waves and platinum colloid particles are supported on the surface of the carbon particles. Then they are washed by centrifugal separation and pure water and are transferred to an acrylic reaction cone while being suspended in pure water. Subsequently, they are ozone-treated while injecting oxygen gas and suspending the carbon particles. After they are ozone- treated, they are centrifugally separated and washed by pure water again. Then an electrode is manufactured by adding a suspension made of polytetrafluoroethylene to the carbon particles and coating the top of carbon paper with them. Thus manufactured electrodes are built in as the fuel side electrode 1 and air side electrode 2 of a fuel cell, and a single cell is formed by providing an electrolytic holding layer 3 between the electrodes 1 and 2. As a result, the performance of the cell can be stabilized.
