摘　　要：利用常规和非常规多水源经RO处理后作为新水源,与非常规单一城市污水厂水源比较,多水源双膜处理工艺产生的浓水水质有所不同。浓水水质检测主要指标包括无机盐(Cl-、SO42-、TDS、全盐量)、有机物(BOD、COD)、氮营养物(NH4+-N、TN)、碱度、硬度等。通过实际工程运行水质动态监测,初步探讨了RO浓水的水质规律及其影响因素,为RO浓水处理处置技术深入研究奠定了基础。Both conventional and non-conventional water sources can be used to produce reclaimed water after being treated by RO.However,different water sources can be used to produce concentrated water of unique chemical composition.In this paper,the key water chemistry indicators including Cl-,SO 2-4,TDS,full-salt,NH + 4-N,TN,alkalinity,and hardness were determined and analyzed.Based on the continuous data of the actual project,the characteristics of RO concentrated water quality as well as the related factors were ...
