【摘要】 曝气生物滤池反冲洗污泥的合理处置是其在推广应用中遇到的难题。反冲洗污泥对有机物和浊度有良好的去除效果,但对TP的去除效果甚微;将其与化学混凝剂复配可满足曝气生物滤池进水水质要求,且TP能维持在较低水平。更多还原

【Abstract】 The reasonable disposal of backwash sludge is one of the main problems in the application of Biological Aerated Filter.This research was made on the bio-flocculation performance of BAF backwashing sludge and its efficiency in bio-chemically enhanced coagulation treatment of domestic sewage.The results show that the backwashing sludge has good enhanced removal efficiency to COD、turbidity,but lower removal efficiency to TP.The combination of backwashing sludge and metal salt coagulant can be used for pretreatment of domestic sewage,which makes the effluent quality suitable for use as influent of BAF,and TP can be maintained at low level.更多还原
