[0004] The existing water quality analyzer has only one filter, which can only provide a light source of one wavelength each time. Every time the water quality monitoring system is started, it can only monitor one pollution factor of sewage. When measuring the next sewage factor, it needs Turn off the water quality monitoring system and manually replace the filter and the reagent in the reagent container, wasting monitoring time
If you need to monitor multiple pollution factors at the same time, you need multiple water quality analyzers, which are costly and take up a lot of space

Embodiment 2
[0072] Figure 4 It is a flow chart of Embodiment 2 of a water quality monitoring method of the present invention, which is a method corresponding to the system described in Embodiment 1, and the method includes.
[0073] Step 401: After the sewage sample to be tested is contained in the water sample container, the controller controls the conduit connected to the water sample container to extract a predetermined type and volume of reaction reagent.
[0074] Step 402: After the reaction between the sewage sample and the reaction reagent is completed, the controller controls the light source to output a light signal.
[0075] Step 403: The optical signal is filtered by a rotating filter to obtain a monitoring optical signal with a wavelength required for monitoring the sewage factor.
[0076] Step 404: The monitoring light signal is received by the monitoring light receiver after passing through the sewage sample in the water sample container and sent to the controller.

Abstract
The invention discloses a water quality monitoring system and a water quality monitoring method. The system comprises a measuring device, a controller, a display, a plurality of reagent containers, a plurality of standby reagent containers, a distilled water container, a cleaning container and a waste liquid container; the measuring device comprises a light source, a rotary light filter plate, a water sample container and a monitoring light receiver; the plurality of reagent containers contain a plurality of reaction reagents for monitoring two pollution factors; each reagent container is equipped with one reaction reagent; the rotary light filter plate comprises at least two light filter plates, and can be used for obtaining monitoring light with at least two wavelengths. By adopting the water quality monitoring system provided by the invention, different wastewater factors can be monitored at the same time by starting the water quality monitoring system once; the same measuring device, the distilled water container, the cleaning container and the waste liquid container are adopted for monitoring different wastewater factors without manually changing the light filter plates, so that wastewater monitoring time is saved, wastewater monitoring cost is reduced and occupied monitoring space is reduced.
Description
technical field [0001] The invention relates to the technical field of optical detection, in particular to a water quality monitoring system and method. Background technique [0002] With the development of industrial and agricultural production, the wastewater and waste produced by industrial and agricultural production are continuously discharged into groundwater or nearby rivers, causing pollution of groundwater and rivers. In order to meet the requirements of sustainable development, it is necessary to conduct real-time monitoring of the water quality of surface water and wastewater from factory sewage outlets, so as to detect polluted surface water and sewage outlets with excessive discharge in time, timely treat them, and protect the water environment to meet the needs of sustainable development. . [0003] The real-time monitoring of sewage mainly detects pollution factors such as Chemical Oxygen Demand (COD), ammonia nitrogen content, and heavy metal content in sewa...
