  • the UV lamps are connected to a power supply and the frame has a cleaning device for cleaning the surface of the protective tubes.
  • the UV lamps with the protective tubes are aligned horizontally and axially in the flow direction in the treatment chamber.
  • the UV disinfection device is built into the clarified wastewater stream emerging from a sewage treatment plant.

  • each point of the wastewater flow does not exceed a certain maximum distance from the radiation sources, nevertheless different flow velocities within the treatment chamber can lead to a part of the wastewater flow not flowing through as it flows past that which is necessary for a disinfection effect Receives UV radiation dose.
  • the invention is therefore based on the object of improving a UV disinfection device to the effect that an almost complete disinfection effect is achieved with the lowest possible use of energy from UV radiation.
  • the invention is based on the consideration that the radiation dose applied, that is to say the local radiation intensity is based on the unit of time, which is decisive for the disinfection effect.
  • the radiation intensity can be increased in faster flowing areas.
  • the radiation intensity can be homogenized by arranging the UV lamps, because the radiation intensity decreases with the distance from the UV lamps.
  • the entry in certain areas can be improved by adjusting the time parameter accordingly.
  • the measures specified in claim 1 form a suitable and particularly effective influence on the flow and force a homogeneous flow distribution of the flowing liquid over the entire cross section of the treatment modules containing the UV lamps along the protective tubes.
  • the mechanical means can be arranged on the frame for holding the protective tubes receiving the UV lamps and / or can be formed by the frame itself.
  • the flow velocity of the flowing liquid can also be achieved through the design of the frame influence in the sense that a flow that is as uniform as possible in the sense of a homogeneous exposure to the locations, the flowing liquid, is achieved with UV radiation.
  • the mechanical means can be arranged in the inlet of the treatment chamber.
  • the mechanical means can be arranged on the cleaning device for cleaning the surfaces of the protective tubes and / or can be formed by the cleaning device itself.
  • the cleaning device serves to remove deposits on the surfaces of the protective tubes from time to time, so that the radiation intensity is not dampened by deposits on the protective tubes. Since the cleaning device is inevitably arranged in the area of the protective tubes, it can also be used for. Influencing the flow rate in the sense of homogenization can be used.
  • the mechanical means can be formed by a parking position of the cleaning device.
  • the cleaning device thus blocks the flow in front and swirls behind it, thereby reducing the resulting flow velocity in an axial region of the cleaning device.
  • An appropriate choice of the parking position enables optimization to be achieved in that the greatest possible proportion of the flowing liquid is reduced in speed so that the microorganisms it contains are exposed to the radiation for as long as possible and receive a corresponding radiation dose.
  • the mechanical means can be formed by baffles.
  • the mechanical means can be formed by baffle plates.
  • baffle plates act as a throttle and reduce the flow velocity within a range specified by the expansion of the baffle plates.
  • An area of reduced flow velocity forms in front of and behind the baffle plate, which can also be caused by eddy currents, but as a result leads to a resulting lower flow velocity.
  • This reduced flow rate is used to reduce the radiation intensity allow the UV lamps to act on the microorganisms in order to effectively eliminate their multiplication potential.
  • control elements can additionally be formed by an arrangement of the UV lamps which is dependent on the required UV radiation dose and / or by the control device which determines the radiation power of the individual UV lamps as a function of the flow rate of the lamps controls the protective tubes along the flowing liquid.
  • UV lamps of adjacent columns can be alternately offset in height.
  • UV radiation is also achieved in those areas in which a radiation minimum would otherwise occur if the UV lamps were not arranged vertically offset in the center of the diagonals of these lamps.

  • Fig. 1 shows a cross section through a UV disinfection device according to the invention.
  • a part of the frame 16 is immersed in the liquid of the treatment chamber 10, while another part is arranged outside the liquid level 12 and carries a drive 24 for a cleaning device 26 for cleaning the surfaces of the protective tubes 20.
  • the cleaning device 26 comprises, starting from the drive, essentially vertical legs 28, on which wipers 30 are arranged, which are moved along the protective tubes 20 during an axial movement and remove deposits.
  • a supply device 32 which can be arranged above or outside the treatment chamber 10, electrical connecting lines 34 lead to the protective tubes 20 and are connected to the UV lamps 22.
  • the connecting lines 34 are fixed to the vertical legs 18 of the frame 16.
  • a configuration which can be used in principle and which is improved compared to the known UV disinfection device consists in the fact that the essentially vertical legs 18 of the frame 16, on which the protective tubes 20 with the UV lamps 22 are attached, for each treatment module 14, 14 ', 14 '' arranged both inside and outside on the protective tubes 20 are. It is thereby avoided 's, that the area between two treatment modules 14, 14', 14 '' flows through faster than the area within the processing modules 14, 14 ', 14''.
  • dividing the frame 16 into a plurality of legs 18, a smaller thickness of the legs 18 is also made possible with the same stability, as a result of which the flow velocity inside the treatment modules 14, 14 ', 14''is less reduced compared to the previous embodiment.

Influencing the flow rate in the middle can be achieved by moving the wipers 30 of the cleaning device 26 into a middle parking position. If there are different flow velocities at height level, an adjustment can also be made by baffles 36 or baffle plates 38 on the legs 18 of the frame 16 or the legs 28 of the cleaning device 26. Baffle plates 38 can also be arranged on the wipers 30. The flow velocities at different height levels can thus be adjusted by appropriate dimensioning and adjustment of the baffle plates 38.
