SO_4^(2-)、COD、Fe^(2+)、Cu^(2+)及其交互作用对消化气中H_2S含量的影响

Influential Factors of SO_4^(2-),COD,Fe^(2+),Cu^(2+) and Interaction on the Volume of Hydrogen Sulphide in Digestive Gas

采用正交试验的方法,探讨了影响消化气中H2S含量的主要因素.通过极差分析和方差分析确定c(SO42-)=5mmol/L,COD=4000mgO2/L,c(Fe2+)=20mg/L,c(Cu2+)=20mg/L时,消化气中H2S含量最小为13.1μg/L.

The main influential factors were discussed for their effects on the volume of H2S in digestive gas through orthogonal tests. Through range and variance analysis, the experiment results showed that the optimum condition is c（SO4^2-）=5mmol/L, COD=4000mgO2/L, c（Fe^2＋）=20mg/L, c（Cu^2＋）=20mg/L, the minimum volume of H2S in digestive gas is 13.1μg/L.
