- Title:
- Design and Commissioning of a Coal-to-Methanol Wastewater Treatment and Reuse Project
- 摘要:
- 某年产30×104 t/a煤制甲醇项目产生的废水包括气化废水、硫回收水、装置冲洗水等，废水处理设施设计规模为120 m3/h，采用调节池+沉淀池+SBR池+曝气生物滤池（BAF）+过滤+消毒为主的处理工艺。SBR池采用低负荷启动，控制进水结束时的氨氮<30 mg/L，出水氨氮<10 mg/L；再经BAF深度处理后，出水COD<50 mg/L，氨氮<5 mg/L，可回用于生产。
- 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.
