[0002] Sludge drying, also known as sludge dehydration, refers to the process of removing most of the water content from sludge through infiltration or evaporation, generally referring to the use of self-evaporation facilities such as sludge drying fields (beds). After the sludge is concentrated, the water content of the sludge is further reduced by physical methods to facilitate the transportation, accumulation, utilization or further treatment of the sludge. There are two types of dehydration (drying): natural evaporation and mechanical dehydration. It is customary to call mechanical dehydration sludge dehydration and natural evaporation sludge drying. However, the negative pressure device of the current sludge deodorization equipment can only absorb the sludge odor, and cannot perform a single filtration, and the subsequent odor treatment cannot improve efficiency.
