摘　　要：介绍汽提后的粉煤气化污水溶解有少量H_2S,微量H_2S逸出后在常压气化污水罐放空管形成无组织排放异味气体,利用现有惰性气体加热炉进行焚烧,既保持了低成本治理,又解决了环保问题。A small amount of hydrogen sulfide dissolued in coal gasification waste water after steam stripping.Discharge of trace hydrogen sulfide from vent pipe of ordinary pressure gasification waste water tank formed an unorganized emissions odor gas which threats health nearby.Incineration can completely control odor gas pollution-with high cost.The process of using existed inert gas furnace to incinerate odor gas was introduced with lost cost,high reliability.A factory uses this process and treats the unorganized emission of odor gas from the gasification waste water tank successfully.The operating cost is almost zero.The odor is no longer felt at 1 meter near the vent pipe of the gasification waste water tank.
