The enhanced removal of carbonaceous and nitrogenous disinfectionn by-product precursors using integrated permanganate oxidation andn powdered activated carbon adsorption pretreatment

摘要

Pilot-scale tests were performed to reduce the formation of a range of carbonaceous and nitrogenous disinfection by-products (C-, N-DBPs), by removing or transforming their precursors, with an integrated permanganate oxidation and powdered activated carbon adsorption (PM-PAC) treatment process before conventional water treatment processes (coagulation-sedimentation-filtration, abbreviated as CPs). Compared with the CPs, PM-PAC significantly enhanced the removal of DOC, DON, NH3+-N, and algae fro
