城市污水污泥深度脱水性能的表征指标
Characteristic Indexes of Deep Dewatering Performance of Urban Sewage Sludge
摘要
Abstract
The feasibility of estimating sludge deep dewatering performance by capillary suction time (CST) and specific resistance to filtration (SRF) was analyzed.And the characteristic indexes of high solid content sludge dewatering-ability were studied.The results indicated that as for high solid content sludge,it was feasible to estimate sludge dewatering-ability by diluting the sludge and testing the CST,while sludge with different solid content could be diluted into the same concentration to compare the dewater-ability.Compared with SRF,CST showed better correlation with water content of dewatered sludge cake,more simple measurement,and better repeatability.Therefore,CST was more preferable to evaluate sludge dewatering ability.关键词
