摘要
水环境污染治理的问题是当前环保领域研究的热点问题。硅藻土因其比表面积大、吸附能力强等优点,近年来在废水处理领域得到了广泛应用,硅藻土的储量丰富、价格低廉等优点使其在废水处理领域具有非常广阔的应用前景。笔者在介绍硅藻土的性质和吸附机理的基础上,综述了近年来国内外将硅藻土应用于处理含重金属离子废水、印染废水、造纸废水、含油废水、城镇污水等废水处理领域的研究进展,最后总结归纳了目前硅藻土处理废水研究的不足,并对硅藻土在废水处理领域的应用前景进行了展望。文章能够为相关领域研究的开展提供信息和研究思路。
Water environmental pollution control is a hot issue in the field of environmental protection.Recently, diatomite is widely used in the field of wastewater treatment because of its large specific surface areaand strong adsorption capacity. The abundant reserves and low price of diatomite make it have broadapplication prospects in wastewater treatment. Based on the introduction of the characters and adsorptionmechanisms of diatomite, this paper reviewed the research progress of diatomite application in the treatment ofheavy metal wastewater, printing and dyeing wastewater, paper waste, oil wastewater, municipal wastewater andso on. Finally, the deficiencies of current research on diatomite application in wastewater treatment weresummarized, and the application prospect of diatomite in wastewater treatment was proposed. This paper couldoffer some basic information and ideas for the related research.
