Abstract:
Taking the reusing project on the treatment of industrial wastewater from machinery processing as exam-ple,the technological characteristics of the reusing treatment,design parameters,treatment effects and running costs of the oil separation+flotation+hydrolysis+acidification+biological contact oxidation+MBR process are introduced. The effluent water quality after the treatment can reach the standard specified in the Recycling of City Sewage and Water Quality of City Miscellaneous Water (GB/T 18920-2002). The project operation practice shows that the system runs steadily and has high treatment efficiency,obtaining great economic and environmental benefits.
