Popis:	106 Coagulation followed by chemical oxidation were employed to remove color. The effects of pH, reaction time, coagulant as well polymer dosage and NaOCl were examined. The results showed that removal efficiencies of chemical oxygen demand (COD) and color by coagulation were 9.14% and 62.33%, respectively. Decolorizaiton was 100% after addition of NaOCl. Coagulation can effectively remove resin and color particles, thus, it can reduce the color. NaOCl could then destruct the color functional groups and also oxidize come organic compounds. The removal efficiency of COD by NaOCl was 34.61%.
