Wastewater treatment system

A system for the treatment of wastewater comprising:

• a tank;
• first and second baffle means dividing the tank into three separate chambers, a first blending chamber, a second decomposition chamber, and a third purification chamber;
• means fluidly interconnecting the first chamber with said second chamber and said second chamber with said third chamber
• air injecting means for injecting air simultaneously into all of said chambers;
• and
• third baffle means dividing said first chamber into an upper anaerobic compartment and a lower aerobic compartment, said air injecting means opening into said aerobic compartment further including wastewater inlet means opening into the lower aerobic compartment;
• wherein said means fluidly interconnecting said first chamber with said second chamber includes a pipe section having an inlet in the upper anaerobic section of said first chamber, and extending through said first baffle means and having an outlet in the upper portion of said second chamber,
• said third baffle means is a funnel formed of corrugated material having an opening at the bottom thereof, said means fluidly connecting said second chamber with said third chamber includes an opening in the upper portion of said baffle means dividing said third chamber from said second chamber, said second chamber includes a baffle spaced from both the bottom of said tank and from said baffle means dividing said third chamber from said second chamber, to prevent solids from exiting said second chamber, and said third chamber includes a vertical outlet pipe in the upper portion, and pumping means mounted in said outlet pipe for pumping wastewater out of said tank.
