Application of Image Enhancement Technology in Bubble Dimension Measurement of deinked pulp flotation column

摘要

A substantial increase in demand of paper causes a severe shortage of wood, paper recycling have become increasingly important; Deinked pulp flotation column has the features of less site area, good treatment efficiency, easily control and so on, which can be wildly used in fiber recycling in abroad. This thesis uses the working principle of ore dressing to recycle secondary fiber in order to apply flotation column in wastepaper recycling. And meanwhile this article primarily study on deinked pulp flotation column which is imported from Canada, and drawing 2D maps of flotation column, Meanwhile comparing the application of image enhancement techniques in bubble dimension measurement of deinked pulp flotation column.
