本文以上海自来水为原水,对电渗析、反渗透装置的进水预处理工艺进行研究。经过滤、药剂和活性炭三个方面作了系统试验並提出了合理实用的工艺参数。 In this paper, Shanghai tap water is used as raw water to study the influent pretreatment process of electrodialysis and reverse osmosis devices. The system tests were carried out on the three aspects of filtration, pharmaceuticals and activated carbon, and reasonable and practical process parameters were proposed.
