烟草废水中含有香精香料、生物碱、酚类、醇类等多种难降解有机物，成分复杂，浓度较高。采用气浮+水解酸化+接触氧化+斜管沉淀+砂滤活性炭组合工艺处理此类废水。运行结果表明，当进水COD为550 mg/L左右时，二级出水COD＜70 mg/L，中水出水COD＜38 mg/L，出水水质分别达到《污水综合排放标准》（GB 8978—1996）的一级排放标准和《城市污水再生利用城市杂用水水质》（GB/T 18920—2002）的再生水回用水质标准。该工艺运行稳定可靠，可操作性强，具有良好的经济效益和环境效益。

Tobacco wastewater contains a large quantity of organic substances,such as essence and spice,alkaloid, phenols,alcohols,etc.,which are characterized by refractory degradation,complex components,and high concentra-tion. The combined process,air flotation+hydrolysis acidification+contact oxidation+inclined tube sedimentation+sand filtration activated carbon,has been used for treating this kind of wastewater. The running results show that when the influent COD is about 550 mg/L,the secondary effluent COD is less than 70 mg/L,and the reclaimed water effluent COD less than 38 mg/L. The effluent water quality meets the requirements of the first level criteria specified in the Integrated Wastewater Discharge Standard (GB 8978—1996) and the reclaimed and recycling water quality standard specified in the City Miscellaneous Water Quality of City Sewage Regeneration and Recycling (GB/T 18920—2002). The practice shows that the combined process runs stably and reliably with high operability and great economic and environmental benefits.
