摘要
冷冻法是在冰点以下温度通过物理相变实现污染物浓缩并回收再生水和有用物质的一种新型废水处理技术。因其对废水无选择性、对容器腐蚀小、无外源污染等优点,近年来受到国内外学者的广泛关注。根据冷冻源的不同可将其分为自然冷冻法和人工冷冻法。本文对现有的冷冻法的不同技术形式的研究进展进行了介绍,并讨论了其研究和开发对我国废水处理领域的意义。
Freezing Process is a physicochemical method for wastewater treatment,which could concentrate contaminants and obtain purged water simultaneously under the temperature below the freezing point.It has gained an increasing concern due to the advantages of less selective for wastewater,lower corrosion for vessels and no addition of chemicals,etc.According to the difference in cold source,the method can be divided into nature freezing process and artificial freezing process.In this paper,research progress of different freezing processes is described.Also,the significance of developing freezing process for wastewater treatment is discussed.
