%X Through the lab and pilot-scale experiments of different measures on the removal of chromium in dringking water sources, the effects of pH value, oxidant of FeSO_4、NaHSO_3 and active carbon on the chromium removal were studied. The results showed that, when the mass concentration of chromium in raw water was 0.5 mg/L,the removal rate of chromium with NaHSO_3 and active carbon was 50% ; the removal rate of chromium was 96.8% in lab experiment and 100% by the process of pilot-scale when the ratio of FeSO_4 · 7H_2O to Cr~(6+) was 16:1 , and the concentration of total chromium, total iron satisfied the requirement of Hygienic Standard for Drinking Water (GB 5749-2006).
