摘要
提出了一种对炼油厂含硫含氨废水处理的新工艺。一般炼油厂处理这类废水的方法都是采用单塔或双塔汽提工艺 ,以脱除废水中的硫化氢和氨 ,H2 S的脱除率较高 ,但废水中的 NH3 - N仍有 80～ 30 0 mg/ L。本文重点介绍了这部分残存 NH3 -N的形态分析 ,并针对其固定铵含量 ,等当量注入苛性碱 ,使酸性废水中的 NH3 - N含量直接降至 30 mg/ L
A new process for refinery sour water treatment is introduced in this paper Single tower or two towers steam stripping processes are used to remove H 2S and ammonia from sour water in conventional refinery, which has high H 2S removal rate, with 80～300mg/L NH 3-N remained in the treated water In the new process, equivalent caustic soda is injected in accordance with ammonium content to directly reduce NH 3-N content bellow 30mg/L based on the analyses on the morphotypes of NH 3-N
