What are the influencing factors of flat ceramic membrane in treating oily wastewater?
Using flat ceramic membrane to treat oil production wastewater, the SS and oil content in the effluent are both less than 1mg/L, and the effluent quality is better than the Al level standard for oilfield reinjection water quality. The optimal conditions for treating oily wastewater using flat ceramic membrane are: optimal aeration rate of 2.0mL/min; The optimal membrane flux is 22.5L/(m2.h), and the operating temperature is 50 ℃. The optimal baffle position is the 2nd baffle. The above experiments and results indicate that the use of flat ceramic membrane to treat oily wastewater can achieve long-term stable operation, and the effluent can fully meet relevant standards. It can be used for the effective long-term operation of low utilization ceramic flat membrane treatment of oily wastewater, and the effluent can be used for the reinjection of low-permeability permeable layers, with good development prospects.
