Method for deodorizing farm air

The invention relates to a method for deodorizing farm air. Farm air deodorizing equipment is applied, which consists of a plastic water curtain (1), an exhaust fan (2), an upright column (3), an airvalve (4), an upper bracket (5), a lower bracket (6), a spray head (7), a drain valve (8) and a water curtain tray (9). According to the method for deodorizing farm air, the deodorizing equipment is mounted in an animal building, the spray head is connected with a water charge pipe, and a drain valve is connected with a water discharge pipe; with the stereoscopic deodorizing equipment made from the plastic water curtain and under the effect of the exhaust fan, the waste gas of the animal building enters from four sides of the deodorizing equipment and then is discharged from the top end of theexhaust fan, and the air in the animal building is subjected to washing and deodorizing treatment; therefore, the growth environment of animals is guaranteed, the deodorizing efficiency is improved,the deodorizing equipment i
