燃煤电厂脱硫废水处理系统改造工艺方案对比分析

Comparative Analysis of Process Schemes for Desulfurization Wastewater Treatment System Transformation in Coal Fired Power Plant

为适应运行参数提升和环保要求的提高,国内某燃煤电厂对脱硫废水的处理系统进行了工艺改造。本文对三种工艺方案进行了分析对比,认为以反渗透系统为核心工艺,采用两级软化加微滤工艺对废水进行预处理的脱硫废水资源化综合利用工艺方案具有明显优势。

In order to adapt to the improvement of operation parameters and environmental protection requirements,a domestic coalfired power plant carried out process transformation on the desulfurization wastewater treatment system.This paper analyzes and compares the three process schemes,and considers that the comprehensive utilization process scheme of desulfurization wastewater resource,which takes reverse osmosis system as the core process and adopts two-stage softening and microfiltration process for wastewater pretreatment,has obvious advantages.
