  • 摘要: 采用PP中空纤维膜组件,对VMD(真空膜蒸馏)和MA(膜吸收)脱氨过程进行了研究。考察了料液pH值(9.0~11.0)、料液进口温度(20~50℃)对脱氨效率的影响。研究结果表明,VMD和MA脱除率分别达85%和99%以上。料液pH和料液进口温度对VMD脱氨效果的影响较大,提高料液pH和进口温度可以明显提高VMD的脱氨效率;料液pH对MA的脱氨效率影响较为显著。对2种膜工艺进行了技术集成,利用该集成工艺可达到99.96%以上的氨去除率,出水可达标排放,并且可以有效防止硫酸铵的二次污染。
    Abstract: Two kinds of membrane technologies- vacuum membrane distillation (VMD) and membrane absorption (MA) were adopted for ammonia removal from wastewater with PP hollow fiber membrane modules. The influences of feed pH (9.0~11.0) and inlet temperature (20~50℃) on ammonia removal efficiency were investigated. The results show that ammonia removal efficiencies of VMD and MA can reach to 85% and 99%, respectively. Feed pH and inlet temperature have a significant influence on ammonia removal of VMD.The increases of feed pH and inlet temperature improve ammonia removal of VMD significantly. But for MA, only feed pH has an obvious impact on ammonia removal. In addition, VMD and MA were integrated for ammonia removal in this work. Ammonia removal efficiency reaches to 99.96% with this new membrane technology. The treated water reaches discharge standard and the secondary pollution of ammonium sulfate can be prevented efficiently.
