Technical Field

[0001] The utility model relates to the field of sludge dehydration, in particular to a novel decompression dehydration drying device. Background Art

[0002] Sludge is a solid precipitate produced by the water and sewage treatment process. Since the properties of various types of sludge vary greatly, classification is very necessary, and their treatment and disposal are also different. According to its source, it can be divided into: municipal sludge (civil sludge, also called drainage cement sewage sludge,), mainly refers to sludge from sewage treatment plants, which is the largest type of sludge. In addition, sludge from water plants also comes from municipal facilities and can be classified into this category. Pipeline sludge, sludge from drainage collection systems. River and lake sludge, sludge from rivers and lakes. Industrial sludge, a mixture of solids and water, oil, chemical pollution, and organic matter produced by various industrial production. In non-specific environments, sludge generally refers to municipal drainage sludge.
