[0002] At present, a large number of dry film or wet film processes are used in the production process of circuit boards. There are different classifications such as developing ink slag, film-removing ink slag, developing dry film slag, and film-removing dry film slag. The film produced after the dry film is removed The slag is characterized by strong alkalinity and high COD, containing resin and a large amount of organic matter; the film slag is in the form of viscose, and its moisture content is as high as 50-80%, resulting in serious environmental pollution and high environmental protection treatment costs

Embodiment Construction
[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0022] refer to Figure 1 to Figure 8 , the present invention provides a single-screw dehydration equipment, comprising a longitudinally arranged screw 1, a helical blade 3 is provided on the rotating shaft 2 of the screw 1, and a lower longitudinal groove matching the helical blade 3 is provided below the helical blade 3 4. An upper cover 5 is provided above the spiral blade 3, and the upper cover 5 and the lower longitudinal groove 4 form a cavity for the rotation of the spiral blade 3;
[0023] The lower longitudinal groove 4 is mainly composed of a plurality of fixed ring pieces 6 and a plurality of moving ring pieces 7 arranged closely spaced along the longitudinal direction. The fixed ring pieces 6 and the moving ring pieces 7 are all circular arc pieces. The moving ring piece 7 is horizontally staggered, and the bottom end of...
