摘要：

针对制酒废水水质和二段生物接触氧化法工艺特点,提出了应用纯好氧工艺处理制酒废水的设计思路,确定了工程设计及工艺运行参数,工程实践表明:工艺对高浓度有机废水治理能够获得较好的污染物去除效果,COD和BOD的去除率分别达到92%和94%以上,出水全部达到《污水综合排放标准》GB8978—1996中的二级标准要求。

Abstract:

The design concept, running&design parameter of pure aerobic process to treat alcohol wastewater are put forward, according to the characteristic of the alcohol wastewater quality and two-stage bio-contact oxidation process. The application results showthat process has high contaminant removal efficiency and the removal rates of COD and BOD₅ are over 92% and 94%, respectively. The quality of the discharged sewage meets the requirement of the national standard ( 2nd level, GB8978—1996) .

Key words: alcohol wastewater, two-stage bio-contact oxidation, comprehensive wastewater discharge standard
