Disclosed is a self-disinfecting drain trap in drainage pipes, featuring an automatic cleaning function using electromechanical oscillators (5) and an automatic disinfecting function using heat (6), UV-C radiation, an antibacterial coating and ultrasound as well as the combined use of the individual active principles; the inner wall of said drain trap has a titanium dioxide nano-coating (3) on which oxidizable organic substances are catalytically-oxidatively decomposed and all types of microorganisms are destroyed. The titanium dioxide nano-coating (3) is activated by irradiating same with at least one light source (4) located inside or outside the drain trap. The oxidative-disinfecting effect of the titanium dioxide nano-coating (3) prevents retrograde microbial contamination of the sealing liquid (7) both from the drainage pipe and by ambient air when the cleaning and disinfecting functions are inactive. |
