The promotion of quality, the people increasingly pay attention to the quality of environmental protection, especially water quality, therefore, water treatment field obtaining gradually
More and more attention.In water treatment procedure, the concentration of water pollutant can be reduced by needing to add water treatment agent,
But when add, additive amount is how much, requires to carry out detecting to water sample just to can determine that.Currently, general method is to sewage
It is sampled, analysis detection is then carried out by special instrument (multi-parameter water-quality detector), determines that pollutant is dense in water sample
After degree, the amount of addition water treatment agent is determined according to result, for stationary sewage source, this method is applicable
, but for the source of sewage of flowing, there are limitations to this method, because sewage is flowing always, the concentration of pollutant
Also it is changed in real time, and samples off-line analysis and need certain time, this will cause testing result and generates hysteresis effect, measurement
Result may be inconsistent with the result of actual water sample, and on-line analysis detection can make up this disadvantage.In addition, for
Some timeliness require relatively high, and do not need the parameter of pre-treatment operation or detection (such as the gold in aqueous solution of substance
Belong to ion, Fe2+、Fe3+Deng), on-line checking is necessary.
Multi-parameter water-quality analyzer currently used in the market is substantially by the way of transmission, as shown in Figure 1, passing through
The mode of transmission, which carries out spectrometric method, can be briefly described as light beam is irradiated on sample from a direction, therewith
After interaction, part light is absorbed by the sample, and part light penetrates sample, reaches detector from opposite direction, absorption spectrum is logical
It crosses computer software to show, the test mode of this spectrum is known as transmission-type measurement, more suitable for off-line analysis, that is, takes
It is detected on instrument after sample.But the case where sampling, such as real-time detection pipeline are difficult to for on-line checking or sample
Certain property of liquid, recycled treated water real-time monitoring etc. are just unsuitable.
Fig. 2 is the structural schematic diagram of existing on-line checking Water Test Kits, as shown in Fig. 2, existing on-line checking water
Matter analyzer mainly carries out repacking design to the main pipeline of water body, and main pipeline is made to have the branch communicated therewith, and
This branch, then optical path can be erected in the two sides of this branch, can be reached with light transmission by way of transmission
Detect water pipe in water quality parameter purpose, due to detection site be in branch rather than main pipeline, this detection mode also only
It is the on-line checking on relative meaning, not on-line checking truly, and this on-line checking Water Test Kits is also
Have the shortcomings that structure is complicated, cumbersome.
