摘要
在天然水体和水处理及使用过程中,发生着一系列的水质转化,本文针对这种转化的安 全风险和过程控制的重要方面进行了论述。由于水质及其循环利用的复杂性,水质转化过程实质 上是一个复合污染形成和变化的过程,在此过程中包含了复杂的物理、化学和生物反应,而这些反 应往往在不同的介质和界面发生,可能导致更毒性的污染物生成、污染效应协同等结果,进而构成 水质的生态安全与健康风险。本文结合自己的实验研究结果,介绍了在水处理中通过控制水质转 化过程、保障水质安全的典型方法。同时,根据本领域的发展趋势,提出并简要阐述了有关的关键 科学技术问题。
A series of water quality transformations is taking place in the natural water, water treatment and water utilization processes. This paper discusses some key aspects related with the safety risk and process control in these transformations . Due to the complexity of water quality and water recycle, the process of water quality transformation is virtually a formation and transformation process for composite pollution. This process includes complicated physical, chemical and biological reactions that take place in different mediums and interfaces, which may result in the formation of some more toxic pollutants and coordinated effects of pollution and resultant The ecological and healthy risk to be induced. This paper introduces some typical methods for controlling the water quality transformation processes and ensuring the safety of water quality in water treatment and water utilization processes based on our research results. Moreover, some key scientific problems is put forward according to the developing trend of environmental sciences and technologies.
