对生活区中水进行紫外及次氯酸钠消毒,对紫外及次氯酸钠消毒的中水前后的常见挥发性有机物进行GC/MS检测、比较,考察消毒前后挥发性有机物的不同,为中水消毒技术提供相关的科学数据.探索出一套成功实现水中有机物富集的固相萃取装置及操作步骤.通过一系列紫外消毒时间的对比,得到4W紫外灯处理500 mL水样的最佳消毒时间为5min.但消毒后副产物不易查找,并对其产生的原因进行了探讨.另外,用次氯酸钠消毒处理水样,次氯酸钠溶液稀释50倍后,在500 mL中水样中加入10.0 mL时,在有机物种类减少方面是最好的,由原来的209种减少到129种,同时产生了一些消毒副产物,如2-氯丙酸癸酯、1,2-二乙氧基,1-溴乙烷、1-溴代十八烷烃、1-氯代十六烷烃等长链卤代烃,浓度较低.
Right living areas of water and sodium hypochlorite for UV disinfection Ultraviolet and sodium hypochlorite to disinfect the water before and after the common volatile organic compounds GC / MS detection,comparison,inspected before and after disinfection of different volatile organic compounds to water disinfection technology to provide relevant scientific data.Explore a set of successful enrichment of organic matter in water SPE devices and the operating steps.Through a series of UV disinfection time contrast,Four W UV lamp handle 500 mL of water disinfection of the best time for 5 min.But after disinfection by-products easy to find and the reasons for its conduct discussed.In addition,the use of sodium hypochlorite disinfection of water,sodium hypochlorite solution diluted 50 times,in 500 mL of water samples by adding 10.0 mL,the types of organic matter reductions is the best,from 209 to 129 species of reduction,while some have disinfection by-products,such as 2-chloro capric acid ester,1,2-ethoxy-2,1-dibromoethane,1-bromo 18 alkanes,1-chloro 16 long-chain alkanes and other halogenated hydrocarbons,the lower concentration.
