摘要:

含氟污泥是光伏光电、半导体、氟化工及电子信息等产业在生产过程中产生的主要污染物,其主要成分为CaF2,具有一定的资源化利用价值。常见的资源化处置方式包括CaF2的高纯提取和含氟污泥的直接再生利用,前者主要有浮选富集法、酸浸纯化法和常压蒸馏法等,后者则是以含氟污泥为原料制备沸石、水泥和玻璃等。其中,玻璃固化处置方法常被用于有害元素的安全稳定固化,可以实现对含氟污泥的高效、稳定处理。本文针对含氟污泥的处置现状与玻璃固化方法展开论述,以期为今后含氟污泥的处置提供借鉴与参考。

Abstract:

Fluorine-containing sludge represents a primary pollutant generated during the production processes of industries such as photovoltaic and optoelectronic devices, semiconductors, fluorochemical engineering, and electronic information industry. Its main component is CaF2, which has potential resource recovery. Common resource utilization approaches include high-purity extraction of CaF2 and direct recycling of fluorine-containing sludge. The former encompasses methods such as flotation enrichment, acid leaching purification, and atmospheric distillation, while the latter involves using the sludge as a raw material to produce zeolite, cement, and glass. Among these, the glass solidification method is frequently employed for the safe and stable immobilization of hazardous elements, enabling efficient and reliable treatment of fluorine-containing sludge. This review discusses the current status of fluorine-containing sludge disposal and the glass solidification method, providing valuable insights and references for future management strategies.

Key words: fluorine-containing sludge, sludge disposal, resource utilization, glass solidification, calcium fluoride
