火电厂废水处理及回用指南

[中文适用范围]： 本标准规定了火电厂废水处理及回用技术要求，包括废水种类、特性、废水处理及回用技术等。本标准将火电厂排水系统分为燃料供应、化学水处理、锅炉及辅机、循环冷却、烟气处理、气化洗涤塔和除灰系统，并根据各系统废水来源进行分类。此外，还根据火电厂各系统的用水要求，给出了废水处理及回用技术要求。制定本标准的目的是为火电厂废水处理及回用提供切实可行的技术指导。本标准适用于燃煤、燃油、燃气（含燃气轮机）、生物质、垃圾焚烧和整体煤气化联合循环（IGCC）火电厂。 [外文原描述]： This document specifies guidelines for wastewater treatment and reuse in thermal power plants, including the types and characteristics of wastewater and the technologies of wastewater treatment and reuse. In this document, thermal power plant drainage systems are divided into fuel supply, chemical water treatment, boiler and auxiliary, recirculating cooling, flue gas processing, gasification scrubber and ash handling. Wastewater from these systems is classified in accordance with its system sources. In addition, technical guidelines for wastewater treatment and reuse are provided according to the water requirements of systems in the thermal power plant. This document is formulated to provide feasible technical guidance for the treatment and reuse of wastewater in thermal power plants. It is applicable to coal-fired, oil-fired, gas-fired (including gas turbine), biomass-fired, waste incineration and integrated gasification combined cycle (IGCC) thermal power plants.
