摘要

为了解辽宁省城市集中式生活饮用水中的三卤甲烷类消毒副产物残留水平,本研究于2015-2016年对全省6个城市的出厂水中THMs含量进行了调查。结果表明,所有出厂水中的4种THMs含量和THMs比值均低于GB5749-2006《生活饮用水卫生标准》的限量标准,未有超标现象。水中4种THMs的检出率依次为DBCM75.6%、DCBM67.8%、TCM66.7%、TBM35.6%。除TCM残留水平远低于美国和俄罗斯外,其余三项指标的残留水平与国内外同行业基本一致。各种THMs占THMs总量的百分比依次为TCM50%、DCBM22.3%、DBCM12.3%、TBM15.4%。水中总THMs远低于美国和俄罗斯的含量水平,但与国内同行业的水平基本一致。
In order to find out the level of THMs disinfection by-products in concentrated drinking water, the THMs in the finished water of six cities in the Liaoning province were investigated from 2015 to 2016 in this study.The results indicated that four THMs concentration and THMs ratio for all samples are lower than the limit requirements of GB5749-2006 "standards for drinking water quality ".The detection rates of four THMs in water were DBCM75.6%, DCBM67.8%, TCM66.7% and TBM35.6%. In addition to the residual level of TCM is far lower than those in the United States and Russia, the residual level of DBCM, DCBM and TBM are basically the same as those in the domestic and foreign industry. The percentage of each THMs in THMs is TCM50%, DCBM22.3%, DBCM12.3% and TBM15.4% respectively. The THMs in finished water are much lower than those in the United States and Russia, but are basically the same as those in the domestic industry.
