摘    要:以北京地区不同类型的土壤——黏土、重粉质黏土、粉质黏土、黏质粉土和砂土为研究对象,通过室内土柱水动力弥散试验,得到了不同类型土壤的弥散系数.穿透曲线测定结果表明,氨氮和有机物在黏土、重粉质黏土、粉质黏土和黏质粉土中运移时穿透曲线大致分为2个阶段,在砂土中的穿透曲线呈逐渐上升并最终达到稳定的趋势.

关 键 词:水动力弥散  运移  穿透曲线  氨氮  有机物

Abstract:The research objects are different kinds of soils including clay,heave silting clay,silting clay,clay silt and sand clay in Beijing area. The dispersion coefficients of different kinds of soils are obtained through hydrodynamic dispersion experiment indoors. The soil column measuring dispersion coefficient is also experimented on breakthrough curve of ammonia nitrogen and organic matter. The results show that the breakthrough curve of ammonia nitrogen and organic matter in clay,heave silting clay and siltin...
Keywords:hydrodynamic dispersion  transport  breakthrough curve  ammonia nitrogen  organic matter
