SURGE ANOXIC MIX SEQUENCING BATCH REACTOR SYSTEMS

摘要

Wastewater treatment systems which utilize an interacting surge anoxic mixzone (1208) for facilitating nitrogen removal and anaerobic sequential batch reaction, clarification and decantation zone (1210)for facilitating aeration for BOD removal and nitrate productionfor the surge anoxic mix zone (1208). Sludge reduction may also beaccomplished by anaerobic recycle (1224).
