摘　　要：利用乙二醇含硝废水中的有效物质与气化灰水除硬工艺结合,使其中有效物质得到利用,减少气化灰水除硬过程中碳酸钠和液碱的加入,减少废水排放量,通过分析数据论证和现场装置改造运行,完全能达到生产工艺排放要求。The effective substances in ethylene glycol nitrate-containing wastewater are combined with the gasification gray water softening process,allowing the effective substances to be utilized and reducing the addition of sodium carbonate and liquid alkali in the gasification gray water softening process,thereby re-ducing wastewater discharge.Through data analysis and on-site facility modification and operation,the pro-cess fully meets the production emission requirements.
