摘　　要：稠油污水因油水密度差小、黏度高、成分复杂等,处理难度大,是目前油田污水处理中的难题。应用水解酸化—生物接触氧化工艺处理国内某油田稠油(油密度0.86￣0.97 g/L)污水,实现了3 000 m3/d的稠水污水达标排放。工程运行一年的结果表明,该技术具有抗冲击能力强、污泥产生量少、处理效果稳定的优点,出水水质达到国家二级污水排放标准(GB 8978—1996),大部分水质指标达到国家一级污水排放标准要求。Heavy oil wastewater is difficult to be treated due to its characteristics such as little difference of density between oil and water, high viscosity and a complex component etc. It introduces the technique of biological membrane hydrolytic acidification-biological membrane contact oxidation to process the heavy oil wastewater from some oil-fields（oil density 0.86 - 0.97 g/L ）. The treatment system established is stable and excellent with a capacity of sewage drainage about 3 000 m^3/d Wastewater Discharge Standard（GB 8978-1996）. The sewage drainage can meet the class Ⅱ of National Wastewater Discharge Standard （GB 8978 - 1996）.
