摘要
采用膜生物反应器(MBR)工艺对炼油废水进行处理,本工艺段位于好氧生化段之后,进水为好氧池出水.实验结果表明:pH≤8时可保证膜丝不出现明显结垢现象,并验证了膜系统对CODCr、SS和浊度有明显的去除效果;在产水跨膜压差达到-0.06 MPa后进行清洗,清洗效果明显.本实验证明MBR工艺在炼油废水的深度处理或回用中具有良好稳定的处理效果.
The membrane bioreactor （MBR） process was used for treatment of refinery wastewater after the aerobic biological treatment and fed by the aerobic biological treatment effluent. The results show that the membrane has not significantly scale formation when the pH ≤8 ; the effect that removes CODCr, SS, and turbidity in refinery wastewater is obvious. The effect is significant when the transmembrane pressure was -0.06 MPa. The experiments show that the membrane bioreactor process is good and steady in refinery wastewater treatment and recycling.
