深层过滤反冲洗过程试验研究

深层过滤过程是水处理工程中的基本单元方法，在油田注水处理、石化厂废水治理方面有很重要的地位。反冲洗过程是深层过滤的最后环节。经试验研究，本文所提出的反冲洗方法（气水反冲洗）具有能耗低、耗时少、冲洗效果好等优点，在工业生产中有着良好的应用。

The Research of Deep Bed Filter Anti - rinse Process Experiment

The deep bed filter is one of the basic units in water treatment engineering, it plays an important role in the produced water treatment of oil field and waste water treatment of refineries. The anti - rinse prosses is the last step of deep bed filter. Under the founation of doing a great number of experiments , the methed obtained by the experiments has many advantages, for instance, low energy consuption, little time consuption and good anti - rinse effect. It can be applied in industry
