1.the wastewater flow rate from acrylonitrile process is 1,300 M3/D 2.the volume of activated sludge treatment is 5,000 M3, but the wastewater contain 1,300 M3/D from acrylonitrile process and 2,700 M3/D from epichlorohydrin process. 3.the COD of inflow is 1,800 ppm, the COD of effluent is 70 ppm, the reduction rate is 96%. 4.the Temp. of acrylonitrile process wastewater could be near 40 oC. 5.we wish the 1,300 M3/D acrylonitrile process wastewater can be dilute and treat in another activated sludge treatment process, and this process , MBR system, could be the equipment for wastewater reuse.
