中文摘要:研究了5种土地处理系统中的常用填料(天然沸石、陶粒、北京土壤、蛭石和砾石)对磷酸盐的吸附和解吸特征,结果表明蛭石与土壤对磷酸盐的吸附效果明显(吸附量分别为1.38 mg/g和1.24 mg/g),陶粒与沸石的磷酸盐吸附效果次之(分别为1.12 mg/g和1.18 mg/g),砾石的磷酸盐吸附效果最差(0.9 mg/g)。5种填料在振荡12 h均达到吸附平衡,吸附量随初始磷浓度的增加而增加。砾石的解吸率最高,北京土壤与沸石的次之,蛭石与陶粒的最低。在所研究的五种填料中,从磷吸附量和解吸率来看,蛭石是较好的磷吸附填料。

Abstract:The adsorption-desorption characteristics of phosphate by five common substrates (savageness Zeolite, Haydite, Soil, Vermiculite and Gravel) used in soil treatment systems were illustrated in laboratory. The results indicate that phosphorus adsorption capacities of various substrates in the descending order are vermiculite and soil(1.38 mg/g and 1.24 mg/g), then haydite and zeolite(1.12 mg/g and 1.18 mg/g), and then gravel(0.90 mg/g). The five substrates all reach adsorption equilibrium after twelve hours’ shaking time, and the adsorption capacity increases as the original phosphorus concentration in the liquid increases. The results indicate that phosphorus desorption efficiencies of various substrates in the descending order are gravel, soil, zeolite, vermiculite and haydite. Considering the phosphorus adsorption capacities and desorption rates of five substrates in the research, vermiculite is one sound substrate in the soil treatment system for phosphorus removal.
