摘　　要：本试验以人工配制的含硫废水作为进水,使用陶粒为生物载体,研究了生物接触氧化处理含硫废水的影响因素,此方法基于硫化物向单质硫的转化。试验结果表明:DO、HRT、进水硫化物浓度、硫化物负荷是生物接触氧化处理含硫废水的主要影响因素。通过控制溶解氧的浓度,去除的硫化物几乎全部转化为单质硫,硫酸盐的生成率小于10%。所需溶解氧水平与硫化物负荷有关。Feeding synthetic influent contains sulphide wastewater, using ceramisite as the biological attachment medium, the impact factors were investigated for a biological sulphide removal process. This process is based on the conversion of sulfide to sulfur. It was found that dissolved oxygen concentration （DO）, HRT, sulphide influent concentration and sulphide loaden were primary impact factors. The removed sulphide almost was converted to element sulfur and the sulfate production was less than 10% by changing the oxygen concentration. The DO correlated with sulphide loading rates.
