| Abstract: | Recently, water source pollution has become serious.Many kinds of organics have been detected in drinking water with higher concentration, and the water quality safety reduced greatly.In order to enhance the removal rate of dissolved organics in water sources, the pilot experiment containing the conventional treatment as well as the ozone and biological activated carbon filter (BACF)was reported in this paper.Taking the raw water from the Huangpu River as the sample, the characteristics and constituents of dissolved organics in the process were investigated.Results showed that the majority of organics were those with low molecular weight (MW)in the raw water, the percentage of low MW (<3000)organics reached 55.9%.In the combined treatment process, the conventional unit removed the organics with high MW (>10000)effectively, and the removal rate was up to 61.1%, while only 7.9% removal rate for low MW(<3000).The function of ozone oxidation was to modify the refractory organics into low MW organics to enhance the performance of BACF, and the removal rate of organics with MW<3000 reached 28.9% via BACF. The majority of trace organics were removed by the coordination of ozone and BACF, the types of trace organics reduced from 77 to 30, and the concentration decreased 67.4%.The trihalomethane formation potential(THMFP)was removed effectively, and the removal rate reached 73.7%. |
