工业冷却系统中水的使用第2部分:成本分析指南

[中文适用范围]： 本文件提供了工业冷却系统中使用再生水的成本分析指南。 本标准适用于采用中水作为补充水的新建工业冷却系统，其中中水来源于工业废水，经废水处理系统产生后回用。 工业废水的来源是企业内部各生产车间。 在本文件中，冷却水平准成本 (LCOCW) 用于比较和确定哪种工业冷却系统每千瓦时排热量更昂贵。 再生水的使用将直接影响冷却系统的运行成本和环境。 附件 A 提供了外部效益，包括正外部性和负外部性，其中考虑了环境、社会和财务因素。 本文件适用于参与新建工业冷却系统中再生水使用的所有类型的利益相关者。 本文件旨在确保任何从事再生水再利用的组织内部的一致性。 本文件提供了一个广泛的框架，可以在其中评估使用再生水的新建工业冷却系统的成本。 使用的货币为当地货币（LCY）。 [外文原描述]： This document provides guidelines for cost analysis of the use of reclaimed water in industrial cooling systems. This document is intended for new-built industrial cooling systems using reclaimed water as make-up water, in which the reclaimed water originates from industrial wastewater and is generated through wastewater treatment systems for reuse. The source of industrial wastewater is from all the production plants inside the enterprise. In this document, the levelized cost of cooling water (LCOCW) is used to compare and determine which industrial cooling system is more expensive per-kilowatt-hour heat removed. Use of reclaimed water will have a direct impact on the operating cost of cooling systems and the environment. External benefits, including positive externalities and negative externalities, are provided in Annex A, which considers environmental, social and financial elements. This document is intended for all types of stakeholders involved in reclaimed water use in new-built industrial cooling systems. This document aims to ensure consistency within any organization engaged in reclaimed water reuse. This document provides a broad framework within which costs for new-built industrial cooling systems using reclaimed water can be assessed. The currency used is local currency (LCY).
