摘要
从蚯蚓处理制浆污泥的流程和空心桨叶干燥机处理流程进行探讨对比,蚯蚓处理污泥既节能又环保,但占地面积大;空心桨叶干燥机处理污泥不节能,但占地面积小。通过讨论,对大规模处理污泥,建议采用蚯蚓处理污泥,处理后的蚯蚓粪用作有机肥。
The paper compared and discussed the processes of earthworm treatment and hollow blade dryer treatment of paper pulp sludge,and the results showed that earthworm treatment sludge was energy-saving and environmental protection,but needed a large area;On the contrary,although hollow blade dryer treatment of paper pulp sludge was not energy-saving,it need only a small area.Through the discussions,for large-scale sludge treatment,the paper recommended to earthworm treatment and the earthworm cast treated as organic fertilizer.
