A tank made of a metal, and the inside of the treatment tank 10 is a sealed space.

A micro-bubble disturbing device 20 is provided with a pumping pump 21, which is disposed outside the processing tank 10. The pumping pump 21 has a water pumping port 211 and a water outlet 212, and a water pumping pipe 22 is connected to the water pumping port 211. The pumping pipe 22 is inserted into the processing tank 10 from the top of the processing tank 10, and the outer end of the pumping pipe 22 extends downwardly and is located at the bottom of the processing tank 10, and an outlet pipe 23 is connected to the water outlet 212. The outlet pipe 23 penetrates into the treatment tank 10 from the top of the treatment tank 10 and extends downward to the bottom of the treatment tank 10.

A venturi structure 231 is formed at a position of the outlet pipe 23 at the top of the treatment tank 10. A nip section 2311 is formed in the middle of the venturi structure 231, and the diameter of the necked section 2311 is smaller than the diameter of both sides thereof. An air inlet 2312 is formed on a circumferential side of the neck portion 2311. The air inlet 2312 communicates with an inner portion of the neck portion 2311, and an inner diameter of the air inlet 2312 is smaller than an inner diameter of the neck portion 2311. .

An intake pipe 24 is connected to the outer end of the air inlet 2312. The outer end of the air inlet pipe 24 is located at the top of the processing tank 10, so that the air inlet 2312 communicates with the top of the processing tank 10. A gravity accelerating section 232 is formed in a portion of the outlet pipe 23 between the venturi structure 231 and the outer end of the outlet pipe 23. In the preferred embodiment, the outlet pipe 23 is connected to the venturi structure. The portion below the 231 forms a gravity acceleration section 232 extending in the up and down direction. The gravity acceleration section 232 is a straight pipe body having the same upper and lower diameters and a diameter larger than the outlet pipe 23 located in the venturi structure 231 and the water outlet 212. The outer portion of the outlet pipe 23 extends to the middle of the bottom of the treatment tank 10.

When the present invention is used, as shown in the preferred embodiment shown in FIGS. 3 and 4, the treatment tank 10 can be used for cultivating microorganisms, fermenting sugars, or treating sewage with sewage by microorganism species. At this time, the treatment tank 10 is filled with a liquid of a culture medium, a saccharide or a sewage, and at the top of the treatment tank 10, a mixed gas generated by the action of air and a microbial strain is present.

In the process of the present embodiment, a strong oxide may be further added to the treatment tank 10. During the agitation of the air, the strong oxide can uniformly redox the pollutants in the sewage to reduce the proportion of the pollutants. Wherein, the strong oxide may be ozone, chlorine dioxide, sodium hypochlorite or hypochlorous acid.

When it is necessary to agitate the liquid in the treatment tank 10, the operation of the water pump 21 for starting the micro-bubble agitating device 20 is performed, the liquid is withdrawn from the bottom of the treatment tank 10 through the suction pipe 22, and the liquid is circulated from the outlet pipe 23.

Raising to the top of the treatment tank 10, and then being inhaled by the venturi structure 231, the liquid is continuously circulated into fine bubbles, which can make the gas and the liquid in addition to uniformly stirring the liquid in the treatment tank 10. The role of washing. When the treatment tank 10 is used in the process of anaerobic sewage treatment, the gas containing hydrogen sulfide inside can be continuously dissolved in the liquid by the aforementioned washing process, and the treatment of the combination of hydrogen sulfide and moisture can be avoided. The piping around the tank 10 saves the cost of equipment and energy required to additionally use the water wash tower to remove hydrogen sulfide.

In addition to the use of the water pump 21 to provide power to drive the liquid to circulate between the water pumping pipe 22 and the water outlet pipe 23, since the vertical and large diameter gravity acceleration section 232 is provided below the venturi pipe structure 231, the mixing is performed. The fine bubble liquid can be gravity-sucked in this vertical gravity acceleration section 232 to accelerate downward, further increasing the velocity of the liquid through the venturi configuration 231, increasing the vacuum attractive force of the intake pipe 24, attracting more The gas enters the venturi structure 231 to form fine bubbles, which increases the number of bubbles agitated by the liquid in the treatment tank 10 and reduces the load on the pump 21.

In the foregoing preferred embodiment of the present invention, the water pump 21 of the microbubble disturbing device 20 is disposed outside the processing tank 10, and thus the advantage that the pumping water pump 21 is easily repaired when the pump 21 fails is provided. However, in addition to the above, the pumping water pump 21 may be configured as a submersible motor pump, and the pumping water pump 21 may be directly disposed in the processing tank 10, and the same effects as those of the above-described preferred embodiment can be achieved.
