ABSTRACT:
The discharge conduit by which clarified sewage is withdrawn from a sewage clarification plant comprises a headwater conduit section and a low-water conduit section, the latter being separated from the former. The two conduit sections are connected to each other by at least one overground tube, the tube being designed as a siphon. An UV irradiation apparatus is provided for disinfecting the clarified sewage. However, the UV irradiation apparatus is not arranged in the discharge conduit, but is built in into the siphon. This solution has the advantage that the UV irradiation apparatus, which is installed overground, is less susceptible to failure and can more easily be serviced.
