摘要：Odor that caused by the composting of green waste such as litter, trees and grassland trim produced in garden, park, green belt and feces will pollute environment. Ammonia is the main component of this gas.This study uses the spray tower and biological filter as the main body of the chemical and biological compound method to remove ammonia. When the amount of the absorbed liquid was 5 L / h, the influent flow from 0.3 m / h to 1.5 m / h has little effect on the treatment effect of the absorption tower. When the inlet ammonia concentration is about 8 000 mg / m, after treatment with the absorption tower, the effluent ammonia concentration is below 100 mg / m. After treatment with biofilter A, the ammonia is basically not detected in the air; after treatment with biofilter B, no ammonia is detected in the air. When the amount of the absorbed liquid was 8 L / h, the effect of inlet flow on the treatment effect of absorption tower is not significant, when the inlet ammonia concentration is about 6 000 mg / m, after treatment with the absorption tower, the effluent ammonia concentration is less than 50 mg / m. After treatment with biofilter A, the ammonia is basically not detected in the air; after treatment with biofilter B, no ammonia is detected in the air. Different spray volume in the same intake flow conditions, the ammonia concentration of the effluent increases with the increase of the inlet concentration.
