In the present solution, the control component and detection components are symmetricly set on the two opposite sides of light source accommodating hole, it may be assumed that control
Component and detection components are symmetrical arranged；Screening is isolated in the detection light loophole 81 and described be symmetricly set on to irradiation loophole 82
8 two opposite sides of light protective case；The benefit being arranged in this way is that the ultraviolet light that the ultraviolet light of detection group intake is absorbed with control group comes from
Very little is differed in the original light intensity of the same circumferential position of light source 1, therefore the ultraviolet light of the two intake；Disadvantage is: but if
Light source, which installs rear position, radial deflection, then the detection data appearance that will lead to control component and detection components acquisition is biggish
Deviation.
The detection method of organic matter detection sensor in the present embodiment comprising following steps:
Step (1) vacuumizes control tube 6, or keeps being full of air in control tube 6, or pour in control tube 6 pure
Water opens the light source 1, and circuit board 4 records the uitraviolet intensity value that the ultraviolet line receiver 5 of this control group receives, and will
The uitraviolet intensity value is denoted as the first uitraviolet intensity reference point；
Step (2) prepares the control water sample that known to N parts of content of organics and content is all different, and the light source 1 is kept to open
It opens, this N parts of control water sample is then passed sequentially through into the control tube 6 respectively, circuit board 4 successively records N parts of control water samples and flows through
The uitraviolet intensity value that the ultraviolet line receiver 5 of control group receives when control tube 6, and the N of acquisition part uitraviolet intensity value is divided
Be not denoted as the second uitraviolet intensity reference point, third uitraviolet intensity reference point ... N+1 uitraviolet intensity reference point,
Middle N is the natural number more than or equal to 3；
Step (3), the N part uitraviolet intensity reference point obtained according to step (2) obtain organic matter in a control water sample
The table of comparisons between content and uitraviolet intensity reference point；
Step (4) keeps the light source 1 to open, and control tube 6 is vacuumized, or keeps being full of air in control tube 6, or
Pure water is poured in control tube 6；Water to be measured is flowed through into the detection pipe 2, circuit board 4 records the reception of this detection group ultraviolet light
The uitraviolet intensity value that device 3 receives, and the uitraviolet intensity value is denoted as uitraviolet intensity detected value, while recording control group
The uitraviolet intensity value is denoted as interim uitraviolet intensity reference point by the uitraviolet intensity value that ultraviolet line receiver 5 receives, will
Interim uitraviolet intensity reference point obtains intensity of light source attenuation ratio divided by the first uitraviolet intensity reference point, and ultraviolet light is strong
Detected value is spent multiplied by intensity of light source attenuation ratio, is obtained uitraviolet intensity lookup value, is then used the uitraviolet intensity lookup value,
The table of comparisons obtained by query steps 3 obtains the content of organics in water to be measured at this time.
In above-mentioned detection method, main disturbing factor is the variation of light source, and the variation of light source is mainly due to temperature
Degree pushes away length using the time with light source, and the temperature of light source can gradually rise；Because in the characteristic of ultraviolet lamp, ultraviolet light it is strong
Degree can become strong with getting higher for temperature, further include connecing with the light source 1 in order to further increase the precision of detection, in shell 7
Touch the temperature sensor 11 for detecting 1 temperature of light source；In the step (1) and step (2), the light source 1 is kept
It opens, then by the temperature of the 11 real-time detection light source 1 of temperature sensor, recording light source (1) is more under different temperatures value
A first uitraviolet intensity reference point and multiple second uitraviolet intensity reference points, multiple third uitraviolet intensity references
Value ... multiple N+1 uitraviolet intensity reference points；Then the step (3) obtains content of organics in a control water sample
The table of comparisons between reference point is forced in the ultraviolet light under different temperatures value with light source；Finally in step (4), institute is equally kept
Light source (1) unlatching is stated, and by the temperature of the temperature sensor (11) real-time detection light source (1), according to current light source (1)
