摘要
针对某电厂2×330 MW机组脱硫废水处理设备腐蚀、废水超标排放的问题,对系统设备及废水水质进行了技术分析,提出了将脱硫废水引入锅炉渣水系统的优化改造措施。结果表明:改造方案在解决了脱硫废水超标排放的同时减少了锅炉除渣系统补水,降低了脱硫废水对设备和管道的腐蚀,产生了较好的环境和经济效益。
For the problems of desulfurization system waste water treatment equipment existing corrosion and excess emissions in 2×330 MW units of a power plant, makes technical analysis for equipment of system and quality of the waste water,puts forward optimizing improvement measures of introducing desulfurization waste water into boiler slag system. The result shows that the retrofit scheme solve the desulfurization waste water excessive emissions, simultaneously decrease the feed water of boiler slag removal system, reduce corrosion of desulfurization wastewater for the equipments and pipes, produce good environmental and economic benefits.
