This invention discloses a wastewater treatment device and method for all-cotton spunlace nonwoven fabric, relating to the field of wastewater treatment technology. The device includes a wastewater treatment tank, a collection tank, a drive structure, two sets of trajectory running structures, and a pusher block. This invention utilizes the coordinated action of the pulling and restraining units in the trajectory running structure to move the pusher block along a rectangular closed trajectory of backward, downward, forward, and upward movement, sequentially completing the functions of drainage, scraping and conveying impurities, and resetting after impurity removal. When the pusher block moves forward, it contacts the opening and closing structure, automatically opening the sealing door through the mechanical linkage of the contact plate, slide rod, connecting plate, guide plate, and connecting rod, and closing it as the pusher block resets. This eliminates the need for a separate power source or sensor for the sealing door, simplifying the device structure and reducing manufacturing costs and control complexity.
