Abstract:
During conventional drinking water treatment process, concentrations of disinfection byproducts (DBPs) cannot be rapidly detected due to their various types and complex detection protocols. In order to obtain suitable organic matter indicators of DBPs formation potential (DBPFP), a surface water collected from Jinpen Reservoir was employed as raw water, and the coagulant aluminum sulfate was used to simulate the conventional water treatment process which consists of coagulation/flocculation, sedimentation, filtration and chlorine disinfection. The relationships between DBPFP and various organic indexes (UV254, DOC, SUVA and the maximum fluorescence intensity of EEMs-PARAFAC components) were established. The results showed that, with the increase of coagulant dosage the removal efficiencies of dissolved organic matter and DBPFP were firstly increased and then remained unchanged. Compared to other indicators, UV254 and target DBPFP (THMs, HAAs, HANs and 1,1,1-TCP) had a better correlation (r2 > 0.93) and was simple to determine, which was suitable for DBPFP indicator parameter. In order to verify the broad applicability of this indicator, it was applied to four kinds of raw water with different water quality, and similar results were obtained. The results suggest that UV254 can indicate DBPFP well, and the production of DBPs can be controlled by optimizing the operational conditions according to its variation in conventional water treatment process.
