Dewatering additive for sludge and use method thereof

The invention discloses a dewatering additive for sludge. The dewatering additive is characterized by comprising a plurality of solid particles, wherein each solid particle is subjected to hydrophobic treatment, and the surface of each solid particle is covered with a hydrophobic layer. The invention also discloses a use method of the dewatering additive for sludge. The use method is characterized in that sludge to be dewatered and the dewatering additive for sludge are uniformly mixed and stirred according to a weight part ratio of 100: (5-50), and then are dewatered through mechanical dewatering equipment or hot drying dewatering equipment. According to the dewatering additive for sludge and the use method thereof, the water filtering holes of filter cloth can be better prevented from being blocked, and sludge dewatering efficiency can be better improved. 本发明公开了一种污泥脱水添加物，其特征在于：包括若干固态颗粒，各固态颗粒为经憎水性处理并使得固态颗粒表面覆盖有憎水层。本发明还公开了一种污泥脱水添加物的使用方法，其特征在于：待脱水污泥与污泥脱水添加物按照重量份100：(5-50)混合搅拌均匀后通过机械脱水设备或热干化脱水设备进行脱水。本发明污泥脱水添加物及
