| 摘 要： | 对深圳市污水处理厂旱季和雨季的剩余污泥泥质进行了分析,并采用桨叶式污泥干化机对剩余污泥的干化特性及干化过程中的污染物排放特性进行了研究.结果表明,相对于雨季剩余污泥,旱季剩余污泥的干化速率总体更高,旱季剩余污泥在含水率由80％降至60％的干化阶段,干化速率比雨季剩余污泥约高1倍,而当含水率低于60％后,两者的干化速率基...

| Abstract: | The basic characteristics of rainy season excess sludge and dry season excess sludge were analyzed in this paper.The drying process in paddle sludge drying machine and the contaminants emission during the sludge drying process were also studied.Results showed that the drying rate of dry season excess sludge was higher than that of rainy season excess sludge.At the drying stage of moisture content descent from 80% to 60%,the drying rate of dry season excess sludge almost double the drying rate of rainy seaso... |
