本文件规定了工业废水处理再利用工艺综合评价的原则和框架，包括: a） 确定目标和范围； b） 说明评估程序；和 c） 确定评价指标（技术指标/子指标、环境指标/子指标、资源指标/子指标、经济指标/子指标）。 本文件描述了如何使用建议的计算方法和推荐的指标对工业废水处理再利用过程进行综合评估。它没有具体说明单一评价指标的方法。 本文件旨在为广泛的工业废水处理和再利用项目利益相关者提供帮助，包括专业人员（规划、管理、设计师和运营商）、行政机构（监测、评估、监管和管理）和地方当局。 本文件适用于 a） 评估、比较和选择工业废水处理回用工艺， b） 实施持续改进， c） 升级现有处理和再利用设施的流程并提高其性能。 在目标和范围定义内考虑综合评估结果的预期应用。

This document specifies the principles and framework for comprehensive evaluation of industrial wastewater treatment reuse processes, including: a) establishing goals and scope; b) illustrating the evaluation procedure; and c) determination of evaluation indicators (technology indicator/sub-indicators, environment indicator/sub-indicators, resource indicator/sub-indicators, economy indicator/sub-indicators). This document describes how to comprehensively evaluate industrial wastewater treatment reuse processes using the proposed calculation approaches and recommended indicators. It does not specify methodologies for single evaluation indicators. The document is intended to provide assistance to a broad range of industrial wastewater treatment and reuse project stakeholders including professionals (planning, management, designers, and operators), administrative agencies (monitoring, assessment, regulation and administration) and local authorities. This document is applicable to a) evaluating comparing and selecting industrial wastewater treatment reuse processes, b) implementing continuous improvements, c) upgrading processes and improving performance for existing treatment and reuse facilities. The intended application of the comprehensive evaluation result is considered within the goal and scope definition.
