With the improvement of people's living standard, the phenomenon of waste on dinner table is becoming more and more serious, and the amount of waste produced by food and kitchen is increasing rapidly. At present, scholars at home and abroad mainly focus on the treatment of solid kitchen waste, and there are few reports on the treatment of catering wastewater. The characteristics of high concentration of organic matter, complex composition and high oil content in the kitchen wastewater determine that the degradation efficiency of the traditional treatment process will be very low, so it is very important to study different treatment processes for the treatment of kitchen wastewater. The self-made Al2O3 ceramic membrane was developed to treat the catering wastewater which is the pollution sources of high concentration causing great pollution to the water around the city. The effects of feed liquid content, feed liquid flow rate, operating pressure and feed temperature on membrane flux, oil droplets and COD removal rate were studied. The result shows that the optimized filtration condition was that the feed liquid was the raw material liquid, the volume flow rate of the feed liquid was 200 L/h, the operating pressure was 160 kPa, and the feed liquid temperature was 25°C. Under the optimized filter conditions, when the membrane was cleaned by homemade alkaline chemical cleaning agents, the regeneration performance of membranes was well and could recovered to more than 95% of original ones.
