Water Quality Characteristics and Treatment Requirements of Concentrated Water in NF System of WTPs in Typical Areas at Home
In recent years,nanofiltration purification technology has been popularized and applied to a certain scale in urban water treatment plants(WTPs)at home,and generally achieved good purification effect.However,a certain amount of concentrated water is generated in the purification process,and its purification treatment and resource reuse have attracted people's attention,and restricted the popularization and application of nanofiltration purification technology.Based on the research results of the application objectives of nanofiltration purification process at home,the paper analyzes the generation,influencing factors and typical water quality characteristics of nanofiltration concentrated water,discusses the typical research progress in the discharge and treatment of concentrated water,and discusses the optimization strategy of nanofiltration concentrated water treatment and disposal.This paper can provide some guidance and reference for the popularization and application of nanofiltration purification system at home.
