Abstract:
To address the low removal efficiency of odor compounds such as 2-methylisoborneol (2-MIB) and geosmin (GSM), as well as the seasonal risk of manganese exceedance in the existing treatment process at Zhejiang J waterworks, a pilot-scale study and engineering application of the pre-ozonation/hydrogen peroxide-biological activated carbon fluidized bed (O3/H2O2-BACFB) advanced treatment process were carried out. The pilot results demonstrated that this process could consistently reduce 2-MIB and GSM from high influent concentrations of 160 ng/L and 50 ng/L to below the detection limit. Compared with the “pre-oxidation+conventional treatment process” and the “O3/H2O2+conventional treatment process”, this process significantly improved the removal efficiency of permanganate index (CODMn) and further reduced the concentration of the disinfection by-product trihalomethance. Based on the pilot results, an advanced treatment process upgrade and transformation was implemented in the waterworks, and the actual operating effect was good. The concentrations of 2-MIB and GSM in the finished water were stable below the detection limit, and the manganese ion was stable below 0.005 mg/L. The removal rates of turbidity and CODMn were also significantly improved, the adaptability to raw water quality was enhanced, and the operational performance was stable. This study provides engineering reference and support for similar plants facing stringent water quality requirements and process upgrades.
