城市中水回用分散/就地回用系统导则分散/就地系统设计原则

[中文适用范围]： 本文件为分散式/现场给水再利用系统（以下简称“现场系统”）的规划、设计原则及考虑事项提供指南。适用于旨在以安全、可靠和可持续的方式实施分散式给水再利用原则和决策的从业人员和当局。本文件涉及分散式/现场给水再利用系统的全部内容，适用于任何净水厂组件（例如来源水收集、处理、储存、分配、运行维护和监测）。本文件包括以下内容： —— 标准术语和定义； —— 系统组件描述及分散式/现场给水再利用系统可能的模式； —— 分散式/现场给水再利用系统的规划原则； —— 常见评估标准和与水质指标相关的示例及其相关说明，但不设定任何目标值或阈值； —— 需要考虑的具体方面和紧急情况应对。本文件未涉及分散式/现场给水再利用系统的设计参数和监管值。 [外文原描述]： This document provides guidelines for the planning, design principles and considerations of a decentralized/onsite water reuse system and water reuse applications in urban areas. This document is applicable to practitioners and authorities who intend to implement principles and decisions on decentralized water reuse in a safe, reliable and sustainable manner. This document addresses decentralized/onsite water reuse systems in their entirety and is applicable to any water reclamation system component (e.g. source water collection, treatment, storage, distribution, operation and maintenance and monitoring). This document provides: — standard terms and definitions; — description of system components and possible models of a decentralized/onsite water reuse system; — design principles of a decentralized/onsite water reuse system; — common assessment criteria and related examples of water quality indicators, all without setting any target values or thresholds; — specific aspects for consideration and emergency response. Design parameters and regulatory values of a decentralized/onsite water reuse system are out of the scope of this document.
