灌溉工程中已处理过的废水的使用指南. 第3部分: 用于灌溉的再利用方案组件

[中文适用范围]： 本文件涵盖了使用处理后的废水 (TWW) 进行灌溉所需的系统组件。 重点强调灌溉方法，主要是滴灌，因为这种方法代表了一种有效的灌溉和节水方法，同时减少了农作物的污染。 尽管使用滴灌技术处理废水（此处为 TWW）的水质和过滤至关重要，但开放式灌溉系统更受欢迎，并且经常用于 TWW 灌溉，因此本文件对此进行了介绍。 本文件涵盖与 TWW 灌溉项目主要组成部分相关的问题，包括以下内容： ——泵站； ——蓄水池； ——处理设施（用于灌溉目的）； ——过滤和消毒； ——分配管网； ——水应用装置：灌溉系统组件和处理。 本文件无意用于认证目的。 [外文原描述]： This document covers the system's components needed for the use of treated wastewater (TWW) for irrigation. Emphasis is placed on irrigation methods, mainly drip irrigation, as this method represents an efficient method of irrigation and water saving, while reducing the pollution of the crops. Despite the fact that water quality and filtration of treated wastewater (herein TWW) using drip irrigation are critical, open irrigation systems are more popular and are frequently used for irrigation with TWW and therefore are covered in this document. This document covers issues related to the main components of a TWW irrigation project, including the following: — pumping stations; — storage reservoirs; — treatment facilities (for irrigation purposes); — filtration and disinfection; — distribution pipeline networks; — water application devices: irrigation system components and treatment. This document is not intended to be used for certification purposes.
