Cannery Waste Treatment by Anaerobic Lagoons and Oxidation Ditch.

摘要

Various mixtures of fruit and vegetable cannery wastes, and domestic sewage were treated by anaerobic lagoons followed by an oxidation ditch for a two-year period. The anaerobic lagoons consistently achieved BOD reductions of 75 to 85 percent at loadings up to 400 lbs BOD/day/acre provided adequate inorganic nutrients were present. The oxidation ditch reduced the BOD to low levels and was shown to be very stable against overload. Power requirements were less than 0.5 kw.hr./lb of BOD removed and the oxygenation capacity of the rotor was about 30 lbs of BOD per foot of length.
