Abstract

The invention relates to a self-disinfecting drain trap in wastewater drains, having an automatic cleaning through an electromagnetic oscillator and an automatic disinfection through heat, UV-C radiation, antibacterial coating, or ultrasound. The inner wall of the drain trap may be coated with a titanium dioxide nano-coating, on which a catalytic oxidizing reduction of organic substances that can be oxidized takes place, and microorganisms are killed. The titanium dioxide nano-coating may be activated through irradiation with at least one light source located inside or outside the drain trap. When the cleaning and disinfection functions are inactive, a retrograde microbial contamination of the barrier fluid is prevented both on the part of the wastewater drain as well as through the ambient air, through the oxidizing disinfecting effect of the titanium dioxide nano-coating.
