厌氧-好氧工艺在含油废水生化处理中的应用

(中国石油冀东油田分公司安全环保处)论述了厌氧-好氧(A/O)工艺的基本原理及工艺参数。该工艺在冀东油田两座废水处理站的应用结果表明,对废水中石油类物质、COD、硫化物去除效果明显。高一联合站及柳一联合站污水经处理后,石油类物质去除率分别为90.6%和96.0%;COD去除率分别为86.0%和91.6%;硫化物去除率分别为94.8%和98.2%,处理后的污水均达到一级排放标准。另外,采用厌氧-好氧工艺的成本相对较低,处理费用低于0.5元/m3。处理后的污水若回注地下,平均费用为4.7元/m3。

Application of A/O Technique to Oily Wastewater Biochemical Treatment

The basic principle, process parameters of anaerobic (A/O) technique are discussed in this paper. The application status of this technique to treat oily wastewater of Jidong Oil Field shows that good removal effects of oily matters, chemical oxygen demand and sulfide have been achieved. The wastewater treated with A/O technique in the sewage disposal station of Jidong Oilfield is agreeable to the sewage drainage standard. In addition, this technology has a low cost.
