The invention provides an environment-friendly 
sewage degreasing device and a use method thereof. The environment-friendly 
sewage degreasing device comprises a tank body, an oil collector, a treatingpond and a filtering plate, wherein a water inlet 
pipe is arranged outside the tank body; an 
oil storage barrel is arranged at one side, away from the water inlet 
pipe, of the outer part of the tank body; a water outlet 
pipe is arranged at the lower end of the 
oil storage barrel; a ventilation pipe is arranged at the upper end of the tank body; the oil collector is arranged inside the tank body; handles are arranged at the upper end of the oil collector; flanges are arranged at the lower end of each 
handle; a sealing plate is arranged at the lower end of each 
flange; an inner 
barrel through hole is formed in the inner side of the lower end of each sealing plate. By means of the 
sewage degreasing device, 
oil can be quickly separated from sewage, and working efficiency of 
grease in the sewage is greatly improved; an oil collecting device can realize filtering of large-particle 
solid wastes, can be detached, is convenient to clean and is more sufficient in filtering; by arranging a filtering plate, sterilizing and 
odor removing effects can be realized while oil removal and better environment-friendly property is realized.
