Purpose of the invention (industrial application field) This invention relates to an aeration device for wastewater, etc. More specifically, it refers to aeration (or conversely, aeration), and it relates to equipment for exposing wastewater and the like to the atmosphere. Here, wastewater, etc. refers to sewage, rainwater accumulation, drainage (pushing out the water inside. Draining it elsewhere), wastewater (water that has become dirty due to use and is no longer useful), and other types of water. say. It is explained that there are two purposes for aerating wastewater as described above.

Methane, hydrogen sulfide, and other volatile organic substances that cause various odors. These are removed by aeration. (2) Oxidation of iron and manganese in wastewater, etc. Iron and manganese in wastewater etc. are oxidized by aeration and precipitate as insoluble hydroxide. In this case, the purpose of aeration is not only to supply oxygen to the water, but also to remove carbon dioxide gas, increase the pH, and act as a catalyst for the air oxidation of iron and manganese.
It also has the effect of supplying OH - ions. (Wastewater treatment for industrial water, Tsuyoshi Okamoto et al., Nikkan Kogyo Shimbun) This invention relates to an aeration device for wastewater, etc., which has the above purpose.

を行なつている。(Prior Art) The conventional technology regarding an aeration device is as follows. According to the revised edition of the Water and Wastewater Handbook (Maruzen Co., Ltd.) (P.2241-243), (1) Aeration devices that use water falling into the air (spray type, plate type, wooden tray type,
(2) Aeration devices using the air diffusion method. This aeration device is a device that typically attaches a porous pipe or perforated plate to a rectangular concrete tank and aerates it with compressed air.
[The device described in (2) above seems to be similar to the device of this application, but it is completely different as detailed below. Furthermore, according to the conventional technology of "wastewater treatment" (Keiji Kaji, Maki Shoten, p. 39, Figure 13), wastewater is pumped into a water tank using a metering pump, air is supplied using an air compressor, and the water is pumped into the water tank. Air is supplied to the pipe, and a synthetic resin ball is installed at the air inlet of the pipe. In this way, aeration is performed.

Reference numeral 1 denotes a water tank (as described above, a water tank for storing sewage, rainwater, drainage water, waste water, etc.), and a suction pipe 4 is provided. A filter 2 is provided at the tip of the suction pipe 4, and a check valve 3 is provided above the filter 2. At the upper part of the suction pipe 4 above the water surface 9, a porous cylindrical body 5 (e.g., an unglazed cylinder, an insulator, a silicone rubber cylinder, a porous ceramic cylinder) is provided with pores of 0.01 mm through which air passes. ] are provided (four in the figure),
This is provided at a length within the range of the suction force of the pump 6 and is connected. The porous cylindrical bodies 4 may have exactly the same diameter, or may have slightly different diameters. (Figure 2)
In this way, the configuration is such that air is sucked through the pores of the porous cylindrical body 5 when the pump 6 is operated. (Needless to say, it comes into contact with waste water, etc.) The rising speed of the sucked air changes depending on the diameter of the porous cylinder 5 [5, 5' in Fig. 2]. Needless to say. (It becomes faster or slower.) 6 is a pump as mentioned above, and 7 is a mounting base for the pump 6. 8 is a discharge pipe of the pump 6, which is communicated with the water tank 1 as shown in the figure. 9 is water in tank 1. Therefore, it is waste water, etc. 10 is a precipitate. (Oxidized iron, manganese, etc.) (Operation) When the pump 6 operates, the waste water 9 from the water tank 1 is sucked in through the filter 2 and is caused to rise through the suction pipe 4 and the check valve 3. Then, air is sucked through a number of porous cylindrical bodies 5. (Negative pressure) Furthermore, to explain, since the porous cylindrical body 5 is connected to a length within the range of the suction force of the pump 6 as described above, the porous cylinder body 5 is connected to the length within the range of the suction force (negative pressure). Air bubbles are melted into the waste water 9 passing through the body 5 and further discharged from the pump 6 to the discharge pipe 8. (It is discharged.) This wastewater etc. 9 is
With a large amount of dissolved oxygen in the air, the discharge pipe 8
Then go back to tank 1. In this way, the amount of dissolved oxygen in the water tank 1 can be increased repeatedly.
