Abstract

The influence of KMnO₄ peroxidation combined with PAC (poly aluminum chloride) coagulation (KMnO₄-PAC) on controlling disinfection byproducts formation potential (DBPsFP) and speciation variation in a representative Karst plateau reservoir (Hongfeng Lake) was investigated. Fourier transform infrared spectroscopy (FTIR) and three-dimensional fluorescence spectrum (3D-EEM) were applied to conjecture DBP formation pathways. Results indicated that, DBPsFP decreased by 17.5% to 73% under the dosage of 0.1,0.2 and 0.4mg/L KMnO₄ compared to untreated water,which might be attributed to the partial deactivation of halogen-active chemical structures and functional groups. In addition, the capture and sweep effect of PAC can further decrease DBPsFP by 27.9% to 86.1% compared to pre-oxidized DOM. The impact of KMnO₄-PAC on DBPsFP was in the order of:trihalomethanes (THM₄)>haloacetic acids (HAA₉)>haloacetonitriles (HAN₄)/haloketones (HK₂)/trichloronitromethane (TCNM). FTIR results showed the increase of peak frequency in fingerprint zone (1000~1300cm^-1) and the decrease of transmittance of main peak at 3300cm^-1, which was mainly attributed to accumulation of hydroxyl/carboxyl/C-O groups and the cleavage of conjugated carbon bonds. Results from 3D-EEM analysis indicated that allochthonous organic matter (humic acid like substances) were reduced as the increase of KMnO₄ dosage. Simultaneously, the peak intensity of protein-like substances increased, which implied that DBPsFP were possibly resulted from protein (amino acid) in untreated DOM.
