- Abstract:
- A coal-to-methanol project produces 30×104 t/a of wastewater including gasification wastewater, sulfur recovery and rinse water. The design capacity of the wastewater treatment facilities is 120 m3/h, and the process includes regulating tank, sedimentation tank, SBR, BAF, filtration, and disinfection. The SBR pool was started at low load to control the influent NH3-N to be less than 30 mg/L at the end of the inflow phase, and the effluent NH3-N to be less than 10 mg/L. Then after the advanced treatment by BAF, the effluent COD is less than 50 mg/L, and NH3-N is less than 5 mg/L stably, which could be reused as production water.
