Aeration train and aeration apparatus for biological purification of wastewater

A continuous feed, cycle, extended aeration activated sludge, wastewater treatment system for the purification of wastewater influent to facilitate aerobic, anoxic, anaerobic treatment phases of activated sludge extended aeration technology including the functions of flow equalization, biological oxidation, nitrifiction, denitrification, secondary sedimentation and aerobic sludge digestion comprising at least one basin with each of said at least one basin comprising;

• a floor for receiving said influent, an influent inlet, an omni-flow partition, said partition being adjacent said inlet and constructed and arranged to direct substantially all of said influent underneath said partition, said partition being suspended above said floor, substantially separating a zone containing a prestratification liquid from said basin liquid, a zone containing a partition being positioned to prevent hydraulic communication between said basin liquid and said pre-stratification zone liquid during an air/off cycle, said partition allowing mix communication between said basin liquid and said pre-stratification zone liquid during an air/on cycle, aeration means mounted to aerate both said pre-stratification zone liquid and said basin zone liquid, said aeration means including:
• at least one elongated air supply flexible conduit extending substantially across a basin liquid surface and having a varying amount of slack in its length, at least one float, means to attach said at least one float to said at least one flexible conduit, at least one bottom aerator and means to attach said at least one bottom aerator to said at least one flexible conduit and decanting means, each of said aeration means and said decanting means having on and off control means, each of said at least one float being movable between a first and second position, said first position being an air/off home position, said second position being an air/on position, whereby for each of said at least one basin,
• when said at least one float means is in its said first home position, said at least one bottom aerator discharges air adjacent the bottom of said at least one basin, said air rising to said liquid surface causing upward currents resulting in a swell beneath said at least one float perpetually sweeping said at least one float away from said home position in a random direction,
• causing the at least one aerator to trail at a relative distance in an amoeboid motion
• moving said at least one aerator omni-directionally over said floor of said at least one basin covering an amoebic shaped area.
