摘要
近年,纳滤净化技术在我国城镇水厂得到一定规模的推广应用,普遍取得了较好的净化效果,但在净化过程中生成了一定量的浓水,其净化处理和资源化回用受到人们关注,并制约了纳滤净化工艺的推广应用.论文基于国内纳滤净化工艺应用目标的调研结果,分析了纳滤浓水的产生、影响因素及其典型水质特征,论述了浓水排放和处理处置方面的典型研究进展,探讨了纳滤浓水处理处置的优化策略.论文可为纳滤净化系统在国内的推广应用提供一定的指导和借鉴.
Abstract
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.
