Xử lý phốtpho trong nước thải chế biến thủy sản bằng mô hình Bardenpho 5 giai đoạn quy mô phòng thí nghiệm

Abstract

    Seafood processing wastewater usually has high phosphorus concentration, and almost Vietnam seafood processing wastewater treatment plants have low phosphorus removal efficiency. The study has designed a Bardenpho 5-stage lab-scale model to remove phosphorus in seafood processing wastewater with different flows: 30 L/day, 50 L/day and 70 L/day. In optimal flow 50 L/day, the treatment efficiencies of COD, NH₄⁺, TP of Bardenpho model were 93.9%; 81.7%, 69.3%, respectively.
