摘　　要：以3种活性污泥(市政污水污泥、可乐废水好氧污泥和可乐废水厌氧污泥)胞外聚合物(EPS)为研究对象,考察储存温度对EPS组分的影响.结果表明,对于3种不同类型的活性污泥EPS,-20℃下储存组分保持最稳定,室温下储存效果最差,4℃储存情况介于前二者之间.对于市政污水污泥和可乐好氧活性污泥EPS,适于在-20℃下储存,此时二者下降率分别为蛋白质9%、20%,糖均为20%.而可乐厌氧活性污泥EPS在3种温度下组分浓度下降率均较大(室温:蛋白质85%,糖80%;4℃:蛋白质80%,糖70%;-20℃:蛋白质30%,糖60%),表明这类EPS不适储存.Effects of temperature on the composition of Extracellular Polymeric Substances （EPS） from 3 types of activated sludge （from treatment of municipal wastewater and anaerobic, aerobic treatment of Cola wastewater） were investigated. The results showed, for all of the three types of EPS, the compositions were most stable at -20 ℃, most changeable at room temperature. The situation at 4 ℃ was the medium of that at -20 ℃ and room temperature. EPS from municipal wastewater sludge and aerobic treatment of Cola wastewater were seemed proper to be stored at - 20 ℃. In this way, the changeable rates of these two types of EPS were 9% , 20% for protein concentration respectively and both of 20% for sugar concentration. Changeable rates of EPS from anaerobic treatment of Cola wastewater were high at all of the three temperatures （at room temperature： protein, 85%; sugar, 80%. at 4℃： protein, 80%; sugar, 70%. at-20 ℃： protein, 30% ; sugar,60% ）, suggesting this type of EPS is not proper to be stored.
