1，4-丁二醇（BDO）生产废水含甲醛，难降解、毒性大、水质水量变化大，处理难度高。试验构建了预曝气水解酸化-高效厌氧反应器-接触氧化-膜生物反应器组合系统处理BDO废水。预曝气水解酸化可有效降低甲醛浓度，降低废水毒性。同时预曝气水解酸化和高效厌氧反应器均可提高废水的可生化性。系统对废水COD的去除率达到90%以上，出水COD满足国家《污水综合排放标准》（GB 8978—1996）一级标准。

1,4-butanediol(BDO) wastewater contains formaldehyde which is so refractory and toxic with great water quality and quantity changes,that it is difficult to be treated. The combined system,pre-aerated hydrolytic acidifica-tion reactor-anaerobic reactor-contact oxidation-membrane bioreactor ,has been constructed for treating the BDO wastewater. Pre-aerated hydrolytic acidification reactor can effectively reduce the formaldehyde concentration so that the toxicity of wastewater can be reduced. At the same time ,the biodegradability of wastewater can be improved by both of the pre-aerated hydrolytic acidification reactor and the anaerobic reactor. COD removing efficiency of the system reaches 90%above,and effluent COD can meet the requirements for the first grade of Integrated Wastewater Discharge Standard(GB 8978—1996).
