| 摘 要： | 目的]探讨磷石膏改良吹填土的机理。方法]通过室内模拟脱盐试验,探讨磷石膏对吹填土理化性质的改良效果。结果]施用磷石膏可提高吹填土的脱盐速率,以混施效果最好,与对照相比差异达0.01显著水平;磷石膏的施入使单位体积水量的淋盐效率下降,增加淋洗用水量;混施磷石膏可以部分抑制吹填土脱盐碱化,淋洗后pH比对照低0.6个单位,总碱度、RSC、SAR都低于对照,而且可使吹填土的离子组成由NaCl型转为CaSO4或Ca（HCO3）2型。结论]磷石膏对吹填土淋洗脱盐不但有促进作用,而且可以改善吹填土的理化性状。不同施用方式的效果存在一定的差异,以与吹填土混合施用效果最好。 |

| Abstract: | Objective]The mechanism that phosphogypsum improved dredged sediment was investigated.Method] The laboratory leaching simulation experiment was conducted to study the desalting effect of phosphogypsum on dredged sediment.Result] Phosphogypsum accelerated the salt moving down and mixed phosphogypsum had a very significant difference(P<0.01) compared to the control.Leaching effect of phosphogypsum on dredged sediment decreased in unit volume water.Mixed phosphogypsum had a potent inhabits of desalting alka... |
