Abstract:
In order to strengthen the removal of odor compounds by conventional treatment process and improve the guarantee ability of water supply safety, the waterworks upgrading process of ferrous iron/hydrogen peroxide (H2O2) advanced oxidation combined with carbon dioxide/lime was designed according to the characteristics of raw water quality in Shenzhen and applied to the process renovation of H waterworks. The results show that the overall effluent quality is obviously improved, 2-MIB reaches the standard stably with average removal rate increased by 1.2 times, the average removal rate of UV254 is increased by 1.0 times, and the chemical stability indexes (LSI, CCPP, AI and LR) are significantly improved. This renovation process adapts to the local water quality characteristics, with short construction period, less investment and no new structures. The investment cost of this transformation is 153.3 yuan/(m3·d-1), and the additional chemical consumption in actual operation is about 0.133 yuan/m3.
