摘要
采用好氧活性污泥法处理中原油田高含盐采油废水,研究不同曝气时间条件下,好氧活性污泥法对高含盐采油废水化学需氧量(CODCr)的去除效果.结果表明:经驯化的活性污泥可适应高含盐环境,且对不同浓度高含盐采油污水均具有较高的CODCr去除率,活性污泥驯化4～6d后,对采油废水CODCr去除率可达90%以上.
The high-salinity produced wastewater from Zhongyuan Oilfield is treated by aerobic activated sludge.The removal efficiency of chemical oxygen demand(CODCr)under different exposed-air times is evaluated.The experimental results indicate that the cultivated activated sludge can suit the high-salinity environment,and it has higher removal efficiency of the chemical oxygen demand(CODCr)to the produced wastewater of different concentrations.After the activated sludge is cultivated 4～6 days,the remove efficiency of CODCr can reach to above 90%.
