应用硅藻土处理废水研究概述

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、价格低廉等特点也使得其在废水处理领域具有比较广阔的应用前景。本文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。

Application of Diatomite in Wastewater Treatment

Water environmental pollution control is a hot issue in the field of environmental protection. Diatomite is widely used in the in the filed of wastewater treatment, because of its large specific surface area and strong adsorption capacity. The abundant reserves and low price of diatomite make it to be broad application prospects in treating wastewater. Based on the introduction of the character and adsorption mechanisms of diatomite, this paper reviewed the research progress of diatomite application in treating Heavy metals wastewater, printing and dyeing wastewater, paper waste, oily wastewater, municipal wastewater and so on. Finally, the deficiencies of the current research on diatomite application in wastewater treatment process were summarized, and the application prospect of diatomite in the field of wastewater treatment was discussed. The current review can offer some basic information and ideas for the related research.
