摘　　要：综述了硅藻土在废水、废气和土壤等环境污染治理领域的研究进展和存在的问题,认为硅藻土作为一种物理化学性能优良的添加助剂,表面结构独特,吸附性能良好,对其进行改性可以适应各种需求。许多研究表明,经过改性的硅藻土对废水、废气和土壤中重金属、无机和有机污染物均具有良好的吸附或降解效果,但是大多研究都处于实验室水平,并且大多都是单因素、单污染因子的实验研究,而对多因素多污染因子的研究较少。具体应用效果还有待于实际应用的验证。Reviewed the research progress and raised some existing problems of diatomite in the treatment of environmental pollution on wastewater,exhaust gas and soil.Diatomite has excellent physical and chemical properties,unique surface structure and good adsorption performance.After modification,it can be adapted to various needs.Numerous studies showed that modified diatomite good adsorption or degradation effect on heavy metals,inorganic and organic pollutants in wastewater or exhaust gas.However,most of the researches are in the laboratory level.And most of them are single-factor and single-pollution factor experimental study,and there are less research on the effect of multi-factor and multi-pollution factor.Therefore their results need to be verified by practical applications.
