摘　　要：在避光密闭的厌氧序批式反应器（ASBR）内，通过充氮吹扫的方式，实现了对磷化氢产量的动态检测。在进水pH值为6．5～7、TP为7mg／L、COD为200mg／L、NH3-N为12mg／L的条件下，磷化氢的小时积累产量与TP浓度呈良好的负相关，而与COD浓度的变化趋势基本一致，并且产生的磷化氢浓度较高。The dynamic determination of phosphine yield was achieved by blowing nitrogen into a closed anaerobic sequencing batch reactor. When the influent pH, TP, COD and NH3 - N are 6.5 to 7, 7 mg/L, 200 mg/L and 12 mg/L respectively, the hourly phosphine accumulation yield has a good negative correlation with TP concentration and is similar to the general trend of COD concentration change. The concentration of generated phosphine reaches a higher level.
