Study on Treatment of Printing Ink Wastewater and Its Effect on the Water's Chroma by Coagulation Method |

| Abstract: | This paper describes the decolorizing experiment using the coagulation method to treat printing ink wastewater with a bluish purple color,pH value between4.5～6.5,COD of 6000～17000/mg·L -1 ,chroma of 100～350,and SS of 200～6500/mg·L -1 .The technological conditions,such as the types of coagulants and their dosages,the pH value,and the types of coagulation aid and their dosage,are optimized.Above 97.0%of decolorizing rate was achieved after treating the wastewater with ferrous polychlorid as coagulant with a dosage of 100/mg·L -1 ,at pH values between4.8～5.5,and cation polyroplene acyl amine (with molecular weight of 15,000.00 and 40% of ion degree )as coagulation aid with a dosage of 0.1/mg·L -1 . |
