| 摘 要： | 将钢渣作为基质应用到人工湿地中,可以提高人工湿地对污水中污染物的去除效率.钢渣可以分为碱性氧气炉钢渣、电弧炉钢渣、高炉钢渣和改性钢渣.以碱性氧气炉钢渣、电弧炉钢渣和高炉钢渣作为基质的人工湿地对污水中总磷的去除率都较高,对模拟污水中总磷的去除率大于对实际污水中总磷的去除率,以高炉钢渣作为基质的人工湿地对污水中总氮的去除率...

| Abstract: | Constructed wetland was a common method in sewage/wastewater treatment.Steel slag was a byproduct in the process of steelmaking.The main mineral composition were tricalcium silicate,dicalcium silicate,olivine,pyroxene,dicalcium ferrite,metal oxides and lime.The steel slag material could be used as substrates in constructed wetlands to improve the removal efficiency of pollutants in sewage.According to different steelmaking processes,steel slag could be divided into basic oxygen furnace steel slag,electric arc furnace steel slag,blast furnace steel slag and modified steel slag.Removal rates of total phosphorus in sewage were high by basic oxygen furnace steel slag,electric arc furnace steel slag and blast furnace steel slag,and removal rates of total nitrogen were high by blast furnace steel slag.Removal rates of total phosphorus in simulated sewage were higher than those in realistic sewage.The pH of effluent in constructed wetlands with basic oxygen furnace steel slag was high,and substrate clogging was easy to occur.Electric arc furnace steel slag could solve above problems.The removal efficiency of total nitrogen in sewage could be increased by changing the experimental conditions. |
