摘要
为解决稠油污水问题 ,利用辽河油区欢四联的稠油污水进行了现场处理试验。试验结果表明 :稠油污水经过斜板隔油池和溶气气浮池预处理后 ,出水油含量和悬浮物均可达到回注和进热采锅炉的要求 ;再经生物处理后 ,COD可达到国家排放标准。
In order to solve the problem of heavy oil sewage, field treatment experiment has been carried out by using heavy oil sewage from Huan 4 gathering station, Liaohe oil province. Experiment result shows that after pre treatment through tilted plate interceptor and dissolved air flotation pit, oil content and suspended particles in outlet water meet the requirement of reinjection and thermal recovery boiler; then, after biological treatment, COD can meet national effluent standard.
