摘　　要：针对某重金属冶炼厂环境集烟气、工艺烟尾气经处理后无法达到排放标准、废水处理无法实现零排放的问题,提出环境集烟气处理、工艺烟尾气处理、废水处理工艺流程的改造方案。环境集烟气处理工艺进行了新增和完善烟气捕集罩以及合理调节个抽风点位的风量等改造;工艺烟尾气处理工艺增加一级动力波洗涤系统、一级离子液吸收系统以及应急脱硫塔系统;废水处理方面则新建了处理工艺。通过对环保设施的改造,大气污染物排放实现了ρ(颗粒物)<10 mg/m~3、ρ(SO_2)<100 mg/m~3的排放标准,废水实现零排放。In view of the problem that the collected flue gas and process flue gas of a heavy metal smel-ting plant cannot reach the emission standard after treatment,and the wastewater treatment cannot a-chieve zero discharge,the optimization scheme of collected flue gas treatment,process flue gas treatment and wastewater treatment were proposed.The environmental flue gas treatment process had been reformed by adding and improving the flue gas capture cover and reasonably adjusting the air volume at each pum-ping point.One dynamic wave washing system,one ionic liquid absorption system and one emergency desulfurization tower system were added to the process flue gas treatment process.Wastewater treatment process was newly built.Through the optimization of environmental protection facilities,the emission standards of air pollutants ρ(particulate matter)<10 mg/m^(3) and ρ (SO2)<100 mg/m^(3) were achieved,and the wastewater was zero discharged.
