In order to improve the operating performance of filter tank and propose the high production water volume, the traditional filter media was replaced by homogeneous particle quartzsand.
目的将快滤池的传统滤层改造为均粒石英砂滤层，为的是改善滤池的工作性能，提高产水量。

By the experiment on quartzsandfilter, the effect and mechanism of phenol removal were studied. A related mathematical model was presented and demonstrated by a project case.
With the structural modification of quartzsandfilter in Daqing oil field, and using the suspended sludge filtration in treating oilfield wastewater, the good experimental results are obtained.
