摘要
人们在饮用水常规处理工艺的基础上,针对不同的污染类型,研究开发的新工艺和新技术归结起来主要有3个方向,即:强化常规处理、原水预处理、深度处理技术。强化常规处理包括新药剂、新材料的研制和新型工艺条件的研究。预处理方法按对污染物的去除途径可分为氧化法和吸附法。应用较广泛的深度处理技术有:臭氧活性炭、生物活性炭、膜分离技术、光催化氧化法和超声技术。
In view of the different types of pollution,the new processes and technologies developed based on the conventional drinking water treatment process can be summed up in three main directions,namely： enhanced conventional treatment,raw water pretreatment and advanced treatment.The enhanced conventional treatment includes the development of new reagents,new materials and the research on new process conditions.Pretreatment method,according to the means of pollutants removal,can be separated into oxidation method and adsorption method.The wildly used advanced treatment technologies includes： ozone activated carbon,biological activated carbon,membrane separation technology,photo-catalytic oxidation method and ultrasound technology.
