Nutrients Removal from Water/Wastewater Using Simultaneous Treatment By An Anammox/PAO Reactor (STAR)

摘要

There is described a number of biological nutrient removal processes including Anammox Process, Biological Phosphorus Removal (BPR), Partial Nitrification, Full Nitrification, Partial Denitrification, Full Denitrification and Denitrification via BPR taking place in a Simultaneous Treatment of Anammox/PAOs Reactor (STAR) coupled with an Anaerobic Lateral Unit (ALU). In one aspect, there is a wastewater treatment system comprises a bioreactor having three consecutive stages: and an anaerobic lateral unit (ALU) coupled to the bioreactor; the bioreactor and A LU are configured to conduct biological removal of nutrients from the wastewater using a plurality of biological processes simultaneously. The three consecutive stages of the bioreactor comprise two Anoxic stages configured consecutively followed by one Aerobic stage. The stages may be oriented vertically and use gravity for fluid flow.
