摘　　要：本文根据美国合同实验方案（ＣＬＰ）的有机分析工作说明及其质量保证／质量控制（ＱＡ／ＱＣ）要求，首次在国内用于废水中半挥发性有机污染物的内标定量分析，并以某污水处理厂的二级处理排出水为实例，从中检出属于美国优先监测污染物的有１６种，其中４种属于我国水环境优先监测污染物，含量在３．１２～４１．４ｎｇ之间，均在允许排放标准值之下，还有９种脂肪烃和糖、酸类的尝试性化合物含量在１．３０～３９．９ｎｇ之间，无三致毒性。采用此技术可提高分析速度，结果可靠。该污水处理厂的二级处理水满足国家排放要求。According to the requirments of statement of work for organic analysis and its quality assurance/quality control (QA/QC) of US EPA contract laboratory program (CLP), The inter-standard quantitative analysis of semivolatile organic compounds in waste water has been perfomed in China for the first time. 16 kinds of compounds belonging to the prior pollutants of US EPA method including 4 kinds of prior pollutants in China have been detected in secondary treatment sewage of a sewage treatment plant.Their concentrations were between 3. 12 and 41. 4 ng which less than emission standard values permitted. 9 kinds of trail compounds which less than emission standard values permitted. 9 kinds of trail compounds which are non-toxic,such as aliphatic hydrocarbon,carbohydrate and the acids were between 1. 3 to 39. 9ng. The analytical speed can be elevated by adopting this method,and its results are very reliable. The secondary treatment effluents of this sweage treatment plant meet the requiment for national emission standard.
