Abstract:

Since the oilfield produced wastewater is characteristic of complicated water quality and bad biodegradability, the feasibility of biological treatment of the oilfield produced wastewater by hydrolysis acidification-anoxic process has been studied and optimal process parameters have been got. The results showthat the processes performed well in treating the oilfield produced wastewater, with the effluent reaching the strictest requirement of the First Grade Effluent Discharge Standards for Wastewater from Petroleum Development Industry (GB 3550—1983).

Key words: wastewater from oilfields, hydrolysis acidification, anoxic process, wastewater treatwent

摘要：

针对采油废水水质复杂、可生化性差的特点，试验采用水解酸化—缺氧法处理采油废水，取得了较为合适的处理工艺参数。试验结果表明:水解酸化—缺氧法对采油废水具有较好的处理效果，缺氧段各工况的出水COD均能达到《国家石油开发工业水污染物排放标准》(GB3550—1983)第一级Ⅰ类标准。
