摘　　要：高盐废水零排工艺中常有超滤、反渗透、MVR蒸发等工艺的组合,但因为零排的水平衡问题,其组合顺序影响投资规模和运行成本。以某资源化项目的废水零排处理工艺为例,对不同的工艺路线进行技术经济分析,研究发现直接采用MVR蒸发全量处理废水能耗过高,采用DTRO减量化后再蒸发结晶更经济,分析成果可为类似项目决策提供参考。The zero-discharge treatment of high-salinity wastewater has the combination of ultrafiltration,reverse osmosis and MVR evaporation,but the combination sequence affects the total investment and operation costs because of the water balance of zero-discharge.Taking the zero-discharge wastewater treatment process of a resource project as an example,this paper makes a techno-economic analysis on different process routes.Analysis found that directly using MVR evaporation for full treatment of wastewater consumes too much energy,and using DTRO reduction followed by evaporation crystallization is more economical.This paper provide reference for the decision-making of similar projects.
