摘　　要：污水含油的处理一直是企业难题。该文对某企业原有含硫污水汽提装置存在的净化水中含油量高、氨水中油含量超标等问题进行分析,并通过新增除油塔、加药罐及油水分离罐等改造,有效降低了净化水中的油含量。除油后净化水中油含量降至90 mg/kg,10%氨水中油含量降至10 mg/kg,可直接作为烟气脱硫的还原剂。硫化氢含油量降至15 mg/kg,品质提升明显。结果表明,该次改造有效去除原酸性水汽提装置中油分,同时将系统中氨和硫化氢进行了资源化回收,具有较好的经济效益。The treatment of oil-containing sewage has always been a difficult problem in the operation of enterprises.This paper analyzes the problems of high oil content in purified water and over standard oil content in ammonia water existing in the original sulfur-containing sewage stripping unit of an enterprise,and the oil removal system is reformed on this basis.By adding oil removal tower,dosing tank and oil-water separation tank,the oil content in purified water is effectively reduced.After oil removal,the oil content in purified water is reduced to 90 mg/kg,and that in 10%ammonia water is reduced to 10 mg/kg.Ammonia water can be directly used as a reducing agent for flue gas desulfurization.The oil content of hydrogen sulfide is reduced to 15 mg/kg,which improves the quality of hydrogen sulfide.The results show that the revamp effectively removes the oil in the original sour water stripping unit,and recycles ammonia and hydrogen sulfide in the system,which has good economic benefits.
