Description

  The present invention relates to a water treatment apparatus that can be used to provide domestic water such as drinking water in an area where there is no power source due to an earthquake, for example.

  It has taken a long time to restore power in the disaster-affected areas such as major earthquakes around the world, and to restore drinking water and other domestic water. The current situation is that they are seeking support, but the reality is that they are not fully prepared.

In order to provide drinking water without using a power source in a stricken area, a disaster drinking water manufacturing apparatus disclosed in Patent Document 1 is known. In this disaster drinking water manufacturing apparatus, water is pumped from a water source. An engine pump is used as the main pump.
JP-A-10-57957

  In the configuration of the conventional drinking water manufacturing apparatus described in Patent Document 1 described above, an engine pump for pumping water from the water source is required, and fuel for driving the engine pump must be prepared. There was a problem.

  An object of the present invention is to solve such problems, and does not require a pump for pumping water from a water source, and does not use fuel even in an area where there is no power source such as a stricken area. It is in providing the water treatment apparatus which can be obtained.

  The water treatment device according to claim 1 of the present invention is a membrane filtration device that is installed in a bottomed state by housing a membrane unit in the device body and being submerged in a water source such as a pond, a lake, or a river, A blower for sending air from below the membrane unit in the filtration device, a suction pump for sucking the water filtered by the membrane filtration device and sending it to the water receiving tank, and a water feeding pump for taking out the water from the water receiving tank It is characterized by that.

The water treatment apparatus according to claim 2 is characterized in that a separation plate that protrudes in a V shape from the outer surface of the main body of the membrane filtration apparatus in a direction opposite to the flow direction of water is provided.
The water treatment apparatus according to claim 3 is provided with a solar power generation device that drives each pump and blower.

  As described above, the water treatment device of the present invention was filtered by the membrane filtration device in which the membrane unit was housed in the device body, the blower for sending air from below the membrane unit in the membrane filtration device, and the membrane filtration device. Living water such as drinking water can be obtained by providing a suction pump that sucks water and sends it to the water receiving tank, and a water feed pump that takes water out of the water receiving tank. In addition, since the membrane filtration device containing the membrane unit is submerged in a water source such as a pond, a lake, or a river and installed in a bottomed state, a pump for pumping water from the water source to the membrane filtration device is provided. This eliminates the need for a treatment pipe for overflow water from the upper end of the membrane filtration device, which can greatly reduce the cost. Further, by providing a separation plate that protrudes in a V shape in the opposite direction to the water flow direction from the outer surface of the membrane filter device main body, resistance due to water flow in the water source is minimized, and membrane filtration is performed. It can suppress that a device moves with the flow of water. Furthermore, a pump and a blower can be driven by providing a solar power generation device even in an area where there is no power source such as a stricken area, and drinking water can be provided by operating a water treatment device without using fuel.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.
In the figure, reference numeral 1 denotes a membrane filtration device that houses a membrane unit 3 in which membrane cartridges are assembled in an apparatus main body 2. This membrane filtration device 1 is submerged in a water source such as a pond, lake, or river. It is installed in a state, and water from the water source enters the apparatus main body 2 from above and below. 4 is a blower for sending air from the lower side of the membrane unit 3 in the membrane filtration device 1, and the water to be treated entered in the membrane filtration device 1 is stirred between adjacent membrane cartridges by the air sent by the blower 4. In the course of ascending, a part of the membrane cartridge permeates into the membrane cartridge and is filtered, and the remaining portion is repeatedly circulated through the membrane filter 1 from the top of the membrane cartridge. Then, the sludge contained in the water to be treated also rises between the membrane cartridges, and acts to scrape off the dirt adhering to the membrane cartridge surface. Reference numeral 5 denotes a suction pump for sucking the water filtered by the membrane unit 3 from the outlet 6 on the upper side of the membrane unit 3 and sending it to the water receiving tank 7. By the way, the water containing the sludge floating above the membrane unit 3 by the air fed by the blower 4 is returned from the upper end of the apparatus main body 2 to the water source. 8 is a sterilization filter provided in the flow path between the suction pump 5 and the water receiving tank 7, and 9 is a drug in the flow path between the sterilization filter 8 and the suction pump 5. A chemical is supplied by a chemical injection pump 10 in a chemical injection tank for feeding sodium hypochlorite. The medicinal pump 10 is interlocked with the suction pump 5, and the medicinal pump 10 is also stopped when the operation of the suction pump 5 is stopped. Reference numeral 11 denotes a UV sterilization lamp provided in the water receiving tank 7 in order to enhance the safety of the water in the water receiving tank 7. Water treated by the UV sterilizing lamp 11 is taken out from the water receiving tank 7 by a water pump 12. Thus, it is used as domestic water such as drinking water through the filter 13. By the way, sludge tends to settle on the lower side of the membrane unit 3 in the apparatus main body 2 by filtration. However, since the membrane filtration device 1 is submerged in the water source, the sludge is returned to the water source. Become.

  Water collected from water sources such as ponds, lakes, and rivers can be used as drinking water and other domestic water as described above, but it often takes a long time to restore power in disaster-stricken areas. In the embodiment, electricity obtained by the solar power generation device 14 is used as a drive source for the blower 4, the suction pump 5, the medicine pump 10, the UV sterilization lamp 11, and the water pump 12. The surplus electricity obtained by the solar power generation device 14 is stored in a storage battery built in the control panel 15.

  The solar power generation device 14 is formed by arranging a large number of power generation panels 16 on a plane, and is configured so that the angle can be adjusted with respect to sunlight so as to be an optimum angle for condensing according to a region. Yes.

  By the way, the membrane filtration device 1 is submerged in a water source such as a pond, a lake, or a river as described above, but in order to minimize the resistance caused by the flow of water in the water source, The apparatus main body 2 of the filtration apparatus 1 is provided with a separation plate 17 that protrudes in a V shape from the outer surface of the apparatus main body 2 in the direction opposite to the water flow direction. Thereby, it can suppress that the membrane filtration apparatus 1 moves with the flow of water.

It is a flow sheet figure of the water treatment equipment in one embodiment of the present invention. It is a top view of the principal part of the water treatment apparatus.
