炼油厂生化处理废水中有机组分的定性分析

将水中的有机组分划分为悬浮性有机物（ＳＯＣ），溶解性可吸附有机物（ＥＯＣ）及溶解性不可吸附有机物（ＮＥＯＣ）三类。分别用Ｇ３型耐酸过滤漏斗及ＧＤＸ－５０２树脂分离并富集炼油厂生化进水及出水中的ＳＯＣ和ＥＯＣ。漏斗滤出的和ＧＤＸ－５０２树脂富集的有机物分别用二氯甲烷洗脱和Ｓｏｘｈｌｅｔ提取。提取物经干燥，浓综后，用ＧＣ／ＭＳ进行分析。结果表明：此方法对炼油厂生化处理废水中有机组分的富集效率为５３．６

IDENTIFICATION AND ANALYSES OF ORGANIC COMPONENTS IN BIOLOGICAL CHEMISTRY TREATMENT OF WASTE WATER FROM REFINERY

Organic components in waste water were classified as suspended organic compounds(SOC), dissolved extractable organic compounds (EOC), and dissolved non extractable organic compounds (NEOC). SOC and EOC in the influents and the effluents of the biological chemical treatment process from a refinery were isolated and pre concentrated using Model G 3 core funnel and GDX 502 resin, and subsequently eluted and extracted with methylene chloride, respectively. The extracts after dry and concentration were then analyzed by GC/MC. The results showed that the enriched portion of TOC ranged from 53.6% to 78%, and the enriched portion of COD corresponded to 47.7%~69.3% of the total COD. Both of the influents and the effluents from A stage of the biological chemical treatment were close in the identified organic compounds, the majority of SOC were n C 9~ n C 29 alkane, and the majority of EOC were phenolic compounds. There were analogous in the identified organic compounds between the effluents of O stage and the effluents of the biological carbon stage in the biological chemical treatment, the relative contents of dibutyl phthalate were higher. The number of identified organic compounds decreased from 120 kinds in the influents to 22 kinds in the effluents by the biological chemical treatment. Higher relative contents of phenolic compounds in the influents were almost removed, and the greater part of other compounds was also removed. The COD in the treated water met the drainage standard.
