Specific implementation mode
To keep the purpose of this utility model, feature, advantage more apparent and understandable, with reference to the utility model
Attached drawing in embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that institute below
The embodiment of description is only the utility model a part of the embodiment, and not all embodiments.Based on the reality in the utility model
Example is applied, the every other embodiment that those skilled in the art is obtained shall fall within the protection scope of the present invention.
The present embodiment provides a kind of circulating water ultraviolet light sterilization test devices to be used for studying ultraviolet lamp power, recirculated water flow velocity
Influence with the ultraviolet light transmissivity of water to bactericidal effect, as shown in Figure 1, including sink 1, ultraviolet lamp apparatus 2, recycle unit
And charger, the recycle unit includes water circulating pump 3, the water main 10 that is arranged on water circulating pump 3, with the main water
The circulation water inlet pipe 11 of the connection of pipe 10, the recycling outlet 9 on the water circulating pump 11, the circulation water inlet pipe 11 connect
It is connected to sink 1,9 one end of the recycling outlet is mounted on 1 bottom of the sink, and the other end connects water circulating pump 3.The main water
The ultraviolet lamp apparatus 2 is connected on pipe 10, the ultraviolet lamp apparatus 2 connects screw clamp 1, and the charger includes being arranged in water
Jet thrust 4 in slot 1, the inflator pump 5 being connect with 4 pipe of the jet thrust are provided with check valve 6 on the water main 10.
One as the present embodiment is preferably provided with the first ball valve 7, is provided on recycling outlet 9 on water main 10
Second ball valve 8, the direction for controlling flow.
Preferably, the structure of ultraviolet lamp apparatus 2 is that ultraviolet lamp is mounted in Double-layered transparent casing to one as the present embodiment.
The present embodiment operation principle is as follows：
Every time before experiment, sink 1 is cleaned up, a certain amount of artificial sea water or dechlorination tap water is then added.People
It makes seawater to be mixed by the tap water of compound crude salt and dechlorination, salinity is 15/1000ths.Every time before experiment, cleaned with business
Liquid cleans the quartzy tube outer surface of ultraviolet lamp, to eliminate influence of the pipe sleeve dirt to exposure.
The coliform of ultraviolet sterilization experiment is commercially available, every time first by a certain number of coliforms before experiment
It is added in screw clamp 1 and uniformly mixes, the ultraviolet light of ultraviolet lamp apparatus 2 can also be adjusted by the way that different wastewater flow rates is added
The transmissivity of 254nm.The jet thrust 4 of sink 1 makes the dissolved oxygen of water body be maintained at (9.3 ± 0.4) mg/L.This jet thrust 4 is same
When so that the concentration of bacterium in sink 1 is kept uniform as a blender.Water in sink 1 is pumped by water circulating pump 3, warp
After crossing a check valve 6, screw clamp 1 is returned by 2 kinds of paths：Circulating path and ultraviolet sterilization path.Circulating path：Cycle
Water pump 3 is drawn water by circulation water inlet pipe 11 from sink 1 enters sink 1 using water main 10 and recycling outlet 9, and ultraviolet light kills
Bacterium path：Water circulating pump 3 is drawn water by circulation water inlet pipe 11 from sink 1 enters water using water main 10 and ultraviolet lamp apparatus 2
Slot 1, ultraviolet sterilization path are equipped with the first globe valve, and circulating path is equipped with the second globe valve, to be adjusted according to test requirements document
The flow that section passes through the water of ultraviolet lamp apparatus 2.The timing since when ultraviolet lamp apparatus 2 is opened is tested, in the different time for exposure
Water sampling detects from sink.
The result shows that the UV power of unit of water body is bigger, bactericidal effect is better；Water body passes through ultraviolet lamp sterilization device
Flow velocity is bigger, and the bactericidal amount of once-through sterilizer is reduced, but since water circulation number increases, total bactericidal effect increases；
254nm ultraviolet transmittances are bigger, and bactericidal effect is better.On the basis of theory analysis and test data, recirculated water is established
The model of ultraviolet sterilization system, and the monovalence inactivation coefficient for having obtained coliform is 0.0062m2/J.It is normal to deactivation rate
The smaller flora of number, increase ultraviolet lamp power killing effect is preferable, and increases day cycle-index killing effect and improve unobvious.
