1.1 本指南涵盖了电渗析（ED）和电渗析逆转（EDR）系统的明确记录保存程序。 1.2 本指南包括ED/EDR和预处理操作和维护数据的启动报告和记录保存。 1.3 本指南适用于所有水域，但不一定适用于废水。 1.4 本指南仅供参考，不应解释为对特定应用所需的所有记录保存的完整描述。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 4.1 ED/EDR系统和任何相关预处理系统的正确操作和维护是获得最佳性能的关键因素。 本指南提供了评估工厂ED/EDR系统、预处理系统和机械设备性能所需的输入数据。 4.2 本指南仅供一般指导，不得代替操作手册和制造商对特定设备或特定应用的建议。 4.3 现场相关、设备设计和监管要求因素阻碍了对所有记录保存的具体建议。因此，本指南仅涵盖与操作和维护相关的一般记录保存。

1.1 This guide covers procedures for well defined record keeping for electrodialysis (ED) and electrodialysis reversal (EDR) systems. 1.2 This guide includes a start up report and record keeping for ED/EDR and pretreatment operating and maintenance data. 1.3 This guide is applicable to all waters but is not necessarily complete for waste waters. 1.4 This is a guide only and should not be construed as a complete delineation of all record keeping required for a specific application. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 4.1 Proper operation and maintenance of an ED/EDR system and any associated pretreatment system are key factors in obtaining optimum performance. This guide provides the necessary input data for the evaluation of the performance of the ED/EDR system, the pretreatment system, and the mechanical equipment in the plant. 4.2 This guide is for general guidance only and must not be used in place of the operating manuals and manufacturer's recommendations for specific equipment or a specific application. 4.3 Site dependent, equipment design and regulatory requirement factors prevent specific recommendations for all record keeping. Thus, only general record keeping relating to operation and maintenance is covered by this guide.
