为了满足工业园区尾水中高环境风险污染物识别检测需求,本文采用气相色谱质谱联用(GC-MS)方法,实现了化工/ 制药工业园区尾水中烷烃、烯烃、苯系物、酮醇酯酸类等有机物的快速定性分析。 根据工业园区重点企业生产工艺和水质调研分析,筛选尾水中具有代表性的 3-己醇、3-己酮、3-(3,5-二叔丁基-4-羟基苯基)丙酸甲酯和 4-溴-2,6-二叔丁基苯酚为典型有机物,并建立了高效液相色谱(HPLC)定量分析方法,该方法对实际样品的加标回收率为 80% ~ 97%,平均回收率为 87% ~95%。 此外,为验证典型有机物的生物降解效果,进行了好氧和厌氧生物序批式实验,结果表明,典型有机物好氧处理中的去除效果优于厌氧处理,有机物浓度去除率为48.0% ~88.8%,COD 去除率为 70.8% ~99.9%,TOC 平均去除率为 54.7% ~79.5%。 为进一步研究工业废水的生物深度处理技术原理或工艺升级改造提供理论和技术支撑。

In order to meet the demand for the identification and detection of high-risk environmentalpollutants in industrial park tail water, this paper adopted the gas chromatography-mass spectrometry(GC-MS) method to achieve the rapid qualitative analysis of alkanes, olefins, benzenes, ketones, al⁃cohols, esters, acids, and other organics in the tail water of chemical/ pharmaceutical industrial parks.Based on the production process and water quality research and analysis of key enterprises within theindustrial park, typical organic compounds, including 3-hexanol, 3-hexanone, methyl 3-(3,5-di-tertbutyl-4-hydroxyphenyl) propionate, and 4-bromo-2,6-di-tert-butylphenol were selected. A high-per⁃formance liquid chromatography (HPLC) method was established to analyze these compounds in thetail water achieving recoveries of 80% to 97% and the average recoveries of 87% to 95%. Furthermoreaerobic and anaerobic biological sequential batch experiments were conducted to verify the biodegrada⁃tion effect of these typical organics. The results showed that aerobic treatment was more effective thananaerobic treatment, with concentration removal rates ranging from 48.0% to 88.8%, COD removalrates from 70.8% to 99.9%, and average TOC removal rates from 54.7% to 79.5%. These findings pro⁃vide theoretical and technological support for the further studies on advanced treatment technology orthe upgrading and transformation of processes for industrial wastewater.
