摘　　要：以猪场废水为研究对象,采用厌氧序批式反应器(ASBR),在避光密闭的环境中,考察COD、TP、NO-3-N及pH值对PH3产生量的影响。结果表明,猪场原液和沼液的PH3释放量分别可达到9.6和6.6 mg/m3;COD和TP浓度的增加以及酸性条件有利于PH3的产生,而NO-3-N对PH3的产生有抑制作用。Anaerobic sequencing batch reactor （ASBR） was used to treat piggery wastewater. The influences of COD, TP, NO3^- - N and pH on production of phosphine were investigated in a closed environment. The results showed that the release quantities of phosphine from the raw wastewater and the biogas slurry were 9.6 mg/m^3 and 6.6 mg/m^3. The increase in COD and TP concentrations and the acid condition were beneficial to the production of phosphine. On the contrary, NO3- - N inhibited the production of phosphine.
