The anaerobic fermentation products of kitchen waste filtrate were separated by centrifugal dehydra-tor,the liquid was kitchen waste fermentation wastewater.Kitchen waste fermentation wastewater has the characteris-tics of large fluctuation in water quality,high oil content,high concentration of organic pollutants and complex compo-sition.This paper mainly expounds the application of oil-seprating tank+air flotation+MBR+NF process in a kitch-en waste fermentation wastewater treatment project in Hu'nan Province.Described the water quality characteristics,the use of technology and operating conditions.The design started from June 2020,from construction to commission-ing and operation till now,the operation is stable,the effluent quality met the third class criteria specified in the Dis-charge Standard of Integrated Wastewater(GB 8978-1996).
