摘　　要：香料香精废水中含有苯、酚、醇、胺、醛类及脂类、油类等物质,硫酸盐含量高,水量、水质变化大。设计采用隔油—气浮—微电解—催化氧化预处理工艺,UASB—两级A/O生化工艺,混凝/沉淀—砂滤深度处理工艺。运行结果表明:当高浓度原水CODCr高达18 073 mg/L时,出水CODCr仍在100 mg/L以下,其他指标均达到《污水综合排放标准》(GB 8978—1996)一级标准。Spices and essence production wastewater contains benzene,phenol,ethanol,amine,aldehyde,fat and oil.In addition,the sulphate concentration is high,wastewater quantity and quality varies constantly.This design used the oil separation-air floatation-micro-electrolysis-catalytic oxidation pretreatment;UASB-two stages A/O bio-chemical process;coagulation/sedimentation-sand filtration advanced process.The results showed： when the CODCr in influent reached 18 073 mg/L,the CODCr in effluent was still below 100 mg/L.Other parameters all met the first grade standards of Integrated wastewater discharge standard（GB 8978—1996）.
