采用好氧气提反应器处理含硫化物废水

Study on the Treatment of Sulphide Wastewater Using Airlift Reactor

采用好氧气提反应器（ａｉｒ－ｌｉｆｔｒｅａｃｔｏｒ）处理人工合成的含硫废水，在ＣＯＤＳ２－＝１．５１，硫化物负荷２—３ｋｇ／（ｍ３ｄ）的条件下，总ＣＯＤ去除率在４０％左右，硫化物的平均去除率稳定在９５％以上．实验结果表明，气提反应器作为脱硫处理单元是完全可行的．并且具有控制简单、操作方便和启动快等优点．剩余污泥中的含硫量在３７％左右，经过处理。

In this paper,airlift reactor is used to treat sulphide waste water,at the sulphide load rate of 2—3kg/(m3·d)(COD∶S2=15∶1),the removal rate of total COD is nearly 40%,average removal rate of sulphide could be above 95%;by the experiment,it is compatible that airlift reactor could be used as the desulphur treatment unit.It has the advantages of easy controlling,operation and rapid startup etc..The sulphur content of residue sludge is 37%(dry),which can be used by proper treatment.
