Project time: 2012 Sewage treatment capacity: 360m3/h
Main process: multi-stage A/O process → high-density precipitation → advanced oxidation → BAF process → reuse system
Coal chemical wastewater treatment and zero discharge system development and application project

China Coal Ordos Energy & Chemical Co., Ltd. Tuk project is the largest chemical project in China and even in the world, the wastewater in the plant mainly comes from phenol-ammonia recycling wastewater, methanol wastewater, gasification circulating water and other comprehensive wastewater, etc., which has a complex composition, and the last end of wastewater treatment process adopts the combination of ozone high-level oxidation and BAF filtering pond, which provides further in-depth treatment of the residual organics in the wastewater and the pollutants such as ammonia and nitrogen, and the concentrated salt water Evaporation device, combined with the evaporation pond, forms a double insurance for the treatment of high-concentration brine, and the reuse rate of wastewater has reached 98%.
