延迟焦化复合废水处理研究

Research on Treatment of Combined Wastewater from Delayed Coking Plant

通过自由沉降和离心分离试验结果的比较，考察了加热离心分离法处理炼油厂含油焦化废水脱除固体颗粒的效果。结果表明，加热离心分离法大大改善了含油焦化废水的脱水和脱固性能，在加热到６０～８０℃时。

Comparing experimental results of freedom sedimentation with ones of centrifugal separation,the effect of heating centrifugal separation method on separating solid particle of oily wastewater from delayed coking plant was reviewed .It was showed that the method has greatly improved performance of de-water and de-solid from oily wastewater,and more 75% solid particle can be deposited, when heating to 60～80℃.
