A plasma-generating ladder-structure module (7), comprising an insulator ladder frame (10) having a ladder structure, the insulator ladder frame being composed of two parallel columns and rungs； a left electrode (11) is perpendicularly formed onto left discharge rods (12) integrally, and a right electrode (14) is perpendicularly formed onto right discharge rods (15) integrally； the left electrode (11) is embedded in the left column of the insulator ladder frame (10), and the left discharge rods (12) are inserted and embedded in the rungs, the cylindrical rungs covering and tightly encircling the left discharge rods (12) concentrically, the annular covering and encircling layer being a dielectric barrier layer (13)； the structure form of the right electrode (14) being embedded in the right column of the insulator ladder frame and the structure form of the right discharge rods (15) being embedded in the rungs of the insulator ladder frame are the same as those of the left electrode (11) and the left discharge rods (12) respectively； and the left and right electrodes (11, 14) are connected to a high-frequency high-voltage power supply in a way that positive and negative electrodes are matched respectively. Further provided is a deodorization, disinfection, and purification device using the plasma-generating ladder-structure module (7). The plasma-generating ladder-structure module is of a chip type, has a small size, is simple, is assembled and used in a modular manner, is convenient and practical, and can be used in the field of development of various secondary products； and the deodorization, disinfection, and purification device based on said module is simple, effective, and environmentally friendly.L'invention concerne un module (7) de structure en échelle de production de plasma, le module comprenant un cadre en échelle isolant (10) présentant une structure en échelle, le cadre en échelle isolant étant constitué de deux colonnes parallèles et de barreaux； une élec
