Engineering analysis for centralized treatment center for scattered industrial wastewater
The scattered industrial wastewater refers to the industrial wastewater with an average daily discharge of less than 3 tons during the production process of small and medium-sized enterprises,which is not classified as hazardous waste and has been approved or recorded.It has the characteris-tics of low water volume,high pollutant concentration,and large fluctuations.A scattered industrial wastewater centralized treatment center in Dongguan City has adopted a combined treatment process of"classified physical and chemical pretreatment+advanced oxidation+A2O+MBR+advanced oxida-tion+denitrification filter+biological aerated filter"to treat the wastewater and the treated effluent steadily meets the project's discharge standards.
