Sustainability evaluation and implication of a large scale membrane bioreactor plant.

摘要: Abstract Membrane bioreactor (MBR) technology is receiving increasing attention in wastewater treatment and reuse. This study presents an integral sustainability evaluation of a full scale MBR plant. The plant capable achieving prominent technical performance terms high compliance rate, low variation effluent quality removal efficiency during long term operation. It also more responsive to the new local standard with rigorous limits. However, electricity consumption found be dominant process resulting elevated life cycle environmental impacts costs, accounting for 51.6% costs. As such, it suggested optimize energy use unit implement sludge management. prolonged membrane span could contribute largely reduced concerns expenses. great theoretical significance applicable value guaranteeing large schemes.
