| Abstract: | A satisfactory result has been obtained due to the treatment of dyeing wastewater by the activated suldge-contact oxidation process.During more than 6 months operations at low temperature,the average COD Cr,average colority and removal rate of the effluent were 79.7±6.0 mg/L,52.8±4.0 times and 84.1±1.7% respectively when the average COD Cr and the average colority of the influent were 567± 40.0 mg/L and 416±37.1 times.This process features a low cost (only 0.79 yuan/m 3),less amount of sludge and conveninet management. |
