摘　　要：通过对底泥来源及组成的分析,认为底泥由可生物降解和不可生物降解两部分组成,并对每部分的蓄积规律及影响因素进行了分析研究,在此基础上建立了稳定塘底泥蓄积公式。根据该公式可得出:①底泥中不可生物降解部分的蓄积与塘运行时间成正比;②可生物降解部分的蓄积存在一个极限值;⑨塘底泥的蓄积与进水水质、水量及塘的运行状况密切相关,同时还受温度的影响。Results of the reseaches on the accumulation of deposits in waste water stabilization pond was summarized. Based on the analysis of the origin and composition of the deposits the authors suggested that the deposits are composed of two fractions: biodegradable and non-biodegradable. A theoretical model discribing the accumulation of benthic deposits was hence established. According to the model, the following conclusions could be drawn: (1) the amount of the accumulation of non-biodegradable is directly proportional to the operation time of the pond; (2) the accumulation of biodegradable part of the deposits will not surpass a maximum value; and (3) the accumulation of pond benthic deposits is closely related to the quantity and quality of influents as well as the operation conditions of the pond.
