摘要
传统净水工艺主要处理水中悬浮物、胶体、大颗粒物质,对于溶解性有机物去除十分有限,由于饮用水标准的不断提高,对溶解性有机物的去除成为传统工艺提标改造的主要内容,预氧化技术是提高水源水中溶解性有机物去除率的有效技术手段之一,本文介绍了水处理工艺中常用的预氧化剂种类、优缺点及其适用的水质。
Traditional water purification process is mainly used to remove suspended solids, colloids and large particles in water;the soluble organic matter removal is hardly achieved by the traditional water purification process. Due to the continuous improvement of drinking water standard, the removal of dissolved organic matter has become the main content of the traditional technology upgrade, preoxidation technology is one of the effective technologies to improve the removal rate of the water soluble organics. In this paper, types of pre-oxidant commonly used in water treatment process were introduced as well as the advantages and disadvantages and application.
