摘要
针对水处理过程中N-二甲基亚硝胺(NDMA)前体物带来的供水安全问题,总结了近年以来国内外关于水体中NDMA的前体物研究以及水处理中相关前体控制技术的进展情况。NDMA主要前体的来源可分为药品与个人护理品、天然有机物、藻源有机物和水处理材料,其前体物主要有亲水性以及小分子量的物质组成。现阶段采用预臭氧化、生物膜法、强化混凝、生物活性炭吸附、RO和UV/H2O2等技术,可对水体中的NDMA前体有着良好去除效果的同时,也面临一定的问题与挑战。
N-dimethylnitrosamine(NDMA)precursors bring about water supply safety problems in water treatment.This article introduces researches on precursors of NDMA in water and related developments in related water control treatment technologies in recent years.The main sources of NDMA are mainly divided into pharmaceutical and personal care products,natural organic matter,algae organic matter and water treatment materials.Its precursors are mainly composed of hydrophilic and small molecular weight substances.At present,pre-ozonation,biofilm method,enhanced coagulation,biological activated carbon adsorption,RO and UV/H2O2 technology have good removal effect on NDMA precursors in water,and also face certain problems and challenges.
