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The discharge conduit by which clarified sewage is withdrawn from a sewage clarification plant comprises a headwater conduit section and a low-water conduit section, the latter being separated from the former.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.

An installation designed for the disinfection of clarified sewage which is withdrawn from a sewage clarification plant by an open discharge conduit, said installation comprising:
- a headwater conduit section of said open discharge conduit having a flow therein;
- a low-water conduit section of said open discharge conduit, said low-water conduit section being separated from said headwater conduit section and having a flow therein;
- at least one overground tube connecting said two conduit sections, said at least one overground tube being designed as a siphon;
- and
- a UV irradiation source built into said siphon for irradiating sewage within said siphon.
An installation designed for the disinfection of clarified sewage which is withdrawn from a sewage clarification plant by an open discharge conduit, said installation comprising:
- a headwater conduit section of said open discharge conduit having a flow therein;
- a low-water conduit section of said open discharge conduit, said low-water conduit section being separated from said headwater conduit section and having a flow therein;
- at least one overground tube connecting said two conduit sections, said at least one overground connecting tube being designed as a siphon;
- and
- a UV irradiation source built into said siphon for irradiating the sewage;
- said siphon comprising:
- an ascending tube comprising a steeply ascending section dipping into the flow in said headwater conduit section;
- a soil tube dipping into the flow in said low-water conduit section;
- a rising overflow bend comprising a gently ascending tube section defining a reaction chamber and an overflow edge situated higher than said reaction chamber, said rising overflow bend connecting said ascending tube and said soil tube;
- said UV irradiation source being built into said gently ascending tube section of said ascending tube.
An installation designed for the disinfection of clarified sewage which is withdrawn from a sewage clarification plant by an open discharge conduit, said installation comprising:
- a headwater conduit section of said open discharge conduit having a flow therein;
- a low-water conduit section of said open discharge conduit, said low-water-conduit section being separated from said headwater conduit section and having a flow therein;
- at least one overground tube connecting said two conduit sections, said at least one overground connecting tube being designed as a siphon;
- and
- a UV irradiation source built into said siphon for irradiating the sewage;
- said irradiation source comprising a plurality of UV radiators and an electric fitting for supplying current to said UV radiators, said plurality of UV radiators and said electric fitting defining a compact modular unit.
An installation designed for the disinfection of clarified sewage which is withdrawn from a sewage clarification plant by an open discharge conduit, said installation comprising:
- a headwater conduit section of said open discharge conduit having a flow therein;
- a low-water conduit section of said open discharge conduit, said low-water conduit section being separated from said headwater conduit section and having a flow therein;
- at least one overground tube connecting said two conduit sections, said at least one overground connecting tube being designed as a siphon;
- and
- a UV irradiation source built into said siphon for irradiating the sewage;
- wherein said UV irradiation source comprises a plurality of UV radiators which are grouped to form a modular radiator group;
- said installation further comprising radiation-previous protective tubes housing each UV radiator, said radiation-pervious protective tubes being permanently built into said siphon.
An installation designed for the disinfection of clarified sewage which is withdrawn from a sewage clarification plant by an open discharge conduit, said installation comprising:
- a headwater conduit section of said open discharge conduit having a flow therein;
- a low-water conduit section of said open discharge conduit, said low-water conduit section being separated from said headwater conduit section and having a flow therein;
- at least one overground tube connecting said two conduit sections, said at least one overground connecting tube being designed as a siphon;
- and
- a UV irradiation source built into said siphon for irradiating the sewage;
- wherein said siphon comprises an ascending tube section and a soil tube section downstream of said ascending tube section, a part of said UV irradiation source being arranged in the ascending tube section and a part of the UV irradiation source being arranged in the soil tube section.
