Abstract
The invention discloses a microbiological method for treating oil field waste water.The method comprises the following steps that firstly, microorganism flocculation is carried out, wherein industrial waste water needing to be treated passes through a water tank containing a microorganism flocculating agent for microorganism flocculation; secondly, membrane filtering is carried out, wherein water treated through the first step is filtered through an ultrafiltration membrane set; thirdly, filter adsorption is carried out, wherein water treated though the second step passes through a fluid bed with biological filler carrying composite microorganisms; fourthly, detection is carried out, wherein water is injected into a pure water tank through a pipeline if the water is detected to be qualified, and the first step is carried out according to a detection result if the water is detected to be not qualified.According to the microbiological method, the system structure is simple, action performance is stable, and the recycling rate of water is high; besides, the method is economical, practical, capable of saving energy and environmentally friendly.
