摘　　要：在人工模拟条件下，串联厌氧好氧塘在总容积相同，不同的容积分配的情况下，污水中的氮、磷去除效率不同，存在最佳容积分配比：Ｖ厌／Ｖ总约为０．２７。在最佳容积分配比处，ＣＯＤ、氮、磷的去除率可分别提高１１．４％、２６．０％、５１．６％。随着负荷、污水Ｃ／Ｎ比、温度、光照时间等因素的变化，氮磷去除呈一定的变化规律。说明了串联厌氧好氧塘氮、磷去除的容积分配效应是客观存在的，合理的容积分配对氮。Under the fixed total volume of the simulant series anaerobic pond aerobic pond condition,there are different removal efficiencies of N and P for synthetic wasterwater with different volume distribution of the series ponds.The optimum distributoin ratio of volume (V A/V T) is about 0.27.At this radio of volume the increased removal efficiencies of COD,N and P are 11.4%、26.0% and 51.6% respectively.The removal rule of N or P in series ponds is affected by the changes of loading,COD/TKN,temperature and illumination time.The results indicate that the volume distributoin effect of N and P removal of the series oxidation ponds exists obviously.It is very important for the removal of N and P that the volume of series ponds is distributed rationally.
