粉煤灰在废水处理方面的应用研究进展
首发时间:2010-08-04
摘要:粉煤灰的多孔性结构、较大的比表面积和一定的静电吸附能力,使粉煤灰具备了用于废水处理的潜在能力。本文主要介绍了粉煤灰在水处理应用中的两种途径:粉煤灰吸附剂和粉煤灰絮凝剂,并就其研究背景和存在缺陷进行了深入的探讨。经研究认为,粉煤灰吸附剂可用于重金属、印染等特殊废水处理,而粉煤灰絮凝剂则可用于城镇污水、工业废水的综合处理,但粉煤灰絮凝剂工艺技术目前还未成熟,有待进一步研究。

Progress of Application Study on Fly Ash in Wastewater Treatment
Abstract:Fly ash, with its porous structure, relatively large specific surface area and electrostatic adsorption ability, has a potential to treat wastewater. This paper mainly introduces the two approaches to the application of fly ash in wastewater treatment -- fly ash sorbent and fly ash flocculant. Besides, the study background and the deficiency are profoundly discussed. Study proves that fly ash sorbent can be apllied to particular wastewater treatment for heavy metal and dyeing while fly ash flocculant can be apllied to comprehensive treatment for municipal wastewater and industrial effluents. However, the process engineering of fly ash flocculant is not yet mature and it requires further study.
Keywords: Environment engineering Fly ash Sorbent Flocculant Wastewater
