摘要 |
Wastewater influent is supplied to an aeration zone having a membrane module. Activated sludge is established in the aeration zone and an oxygen surplus is maintained by controlling a rate of oxygen supplied to the aeration zone. Wastewater influent is mixed with the activated sludge to form a first mixed liquid. A portion of the first mixed liquid is filtered to form a filtrate and unfiltered activated sludge. The unfiltered activated sludge is mixed with the activated sludge in the aeration zone to form the first mixed liquid. A portion of the first mixed liquid is transferred from the aeration zone to an anaerobic zone, and a second portion of first mixed liquid is mixed with activated sludge in the anaerobic zone to form a second mixed liquid. The second mixed liquid is recycled to the aerobic zone. |
