Aeration tank of organic waste liquor and aeration apparatus using the tank

A device for aerating organic waste fluid, comprising:

• an outer tank;
• an aeration tube having upper and lower portions disposed within said outer tank;
• at least one suction hole located in a periphery of said lower portion of said aeration tube;
• at least one scatter hole located in a periphery of said upper portion of said aeration tube;
• a gas-diffusion head located in an interior of said aeration tube;
• a gas source communicating with said gas-diffusion head at a second end;
• and
• a bubble transfer tube interconnected to said aeration tube at an upper end of said aeration tube.

A device for aerating organic waste fluid, comprising:

• at least two aeration units, said aeration units comprising:
• an outer tank;
• an aeration tube having upper and lower portions disposed within said outer tank;
• at least one suction hole located in a periphery of said lower portion of said aeration tube;
• at least one scatter hole located in a periphery of said upper portion of said aeration tube;
• an air-diffusion head located in an interior of said aeration tube;
• and
• a gas source communicating with said air-diffusion head;
• a raw liquid supply tube operatively connected to said outer tank of a first of said aeration units;
• a bubble transfer tube communicating at a first end with an upper end of said aeration tube of said first aeration unit, and communicating at a second end with a sludge sedimentation tank;
• a first return tube communicating at a first end with said aeration tube of a second of said aeration units, and communicating at a second end with said sludge sedimentation tank;
• and
• a treated water reservoir tank communicating with said outer tank of said second aeration unit.
