摘　　要：为验证泥沙、风沙投放于水质不良的水体中,是否具有净化水质的争议,用污染程度较轻的水体为实验对象,以活性炭和硅藻土作为对照组,对比泥沙和风沙对水质净化的效果,而进行了添加试验。结果表明,四种添加物都会对水体的理化性质产生影响,泥沙与风沙净化水质的效果虽不及活性炭和硅藻土,但差异性不显著。得出添加适量的泥沙或风沙会在一定程度上发挥净化湖泊湿地水质的作用。This paper addresses the argument about whether sediment and wind sand can improve water quality.Water with less pollution was used as the experimental object and activated carbon and diatomite were used as the control group.The effect was tested while adding.The results showed that the four additives would affect the physical and chemical properties of the water.Although the effect of sediment and sand on purifying water was not as good as that of activated carbon and diatomite,the difference was not significant.It was concluded that adding an appropriate amount of sediment or wind sand would play a role in purifying the water quality of lake wetlands to a certain extent.
