摘　　要：分析了某制药企业废水生物处理站进出水中有机污染物的相对分子质量分布和气相色谱-质谱图谱,提出了根据废水水质特性有针对性地确定制药废水处理工艺的新思路。实验结果表明:进出水中的有机污染物主要是相对分子质量小于1 000的物质,且主要来源于车间5排放的COD比重大、水量小的工段废水;采用旋转蒸馏预处理法处理车间5废水,可使废水站进水COD降至2 500～3 500 mg/L,出水COD小于800 mg/L,达到入网排放要求。The relative molecular mass distribution and GC-MS spectrum of the organic pollutants in the influent and the effluent of the biological treatment plant of a pharmaceutical factory were analyzed. It is put forward that the treatment process choice should be based on the wastewater quality. The experimental results show that： The organic pollutants in the influent and effluent are mainly substances with less than 1 000 of relative molecular mass, most of the pollutants are from the high COD-small quantity wastewater discharged from workshop-5; The workshop-5 wastewater was pretreated by revolving distillation process with COD decreased from 2 500 -3 500 mg/L to 800 mg/L, which can meet the requirements for discharge into the biological treatment system.
