Alternatively, the COD analyzer uses a chemical oxidant (e.g., potassium dichromate) to oxidize and decompose reducing substances (e.g., organic substances) in the rainwater, and the COD can reflect the degree of pollution of the rainwater by the reducing substances, whereas since the organic substances are the most common reducing substances in the water body, the COD reflects the degree of pollution of the rainwater by the organic substances to some extent, and the higher the COD is, the more serious the pollution is. For example, the COD analyzer utilizes that an oxidant itself is reduced from hexavalent chromium (Cr6+) to trivalent chromium (Cr3+) during a chemical reaction, the solution color is changed from orange to green accordingly, the chromate reduction reaction and the color change are directly proportional to the concentration of oxidizable substances in a sample, and thus, the optical quantification of the reduced chromate concentration is used as an index of Chemical Oxygen Demand (COD) of rainwater to obtain a COD analysis result. The water quality analysis result corresponding to the water quality analysis includes a COD analysis result and the above analysis data.
As shown in fig. 1 and fig. 2, in the embodiment of the present invention, the automatic sampler is used for automatically sampling and reserving a sample for the monitoring system to perform water quality analysis on the rainwater that is automatically sampled and reserved. Wherein, the setting of automatic sampler can prevent to make mistakes at monitoring system's relevant instrument and part and lead to the analysis result to make mistakes or not in time analyze under the condition of rainwater, can take out the water sample in the automatic sampler for the manual work examines whether relevant instrument and part make mistakes or carry out water quality analysis through monitoring system to the rainwater of automatic sampling and leaving a sample in the automatic sampler.
As shown in fig. 1 and 2, in the embodiment of the present invention, the data concentration module is configured to receive the water quality analysis result and transmit the water quality analysis result to the online platform. Optionally, the data concentration module comprises a data collection transmission instrument and a company data concentrator, the data collection transmission instrument is in wired connection with the rain gauge, the flowmeter, the turbidity analysis module (turbidimeter), the temperature module (thermometer), the PH analysis module (PH analyzer) and the COD analyzer through RS485, receives data obtained by the rain gauge, the flowmeter, the turbidity analysis module (turbidimeter), the temperature module (thermometer), the PH analysis module (PH analyzer) and the COD analyzer, such as water quality analysis results, data obtained by the rain gauge and the flowmeter and transmits the data to the company data concentrator through LoRa wireless connection, the data is transmitted to a (cloud) online platform through a TCP or IP protocol by the company data concentrator, the (cloud) online platform can display and store the data for related personnel to monitor and backtrack on the online platform, timely understanding the rainwater quality condition and taking corresponding measures. It should be noted that, the company data concentrator is arranged to avoid the collection of the related data lost when the (cloud) online platform is abnormal, and on the other hand, the online platforms of the company and other information network systems are relatively independent and have confidentiality, if the data are directly transmitted to the (cloud) online platform by each analyzer or module, not only the hardware technology of the corresponding analyzer cannot be achieved, but also the synchronism of the data cannot be ensured, and the obtained data are difficult to use. It should be noted that, in the embodiment of the present invention, the data acquisition and transmission instrument is a part of the monitoring system, and in other embodiments, the data acquisition and transmission instrument may be an independent part connected to the monitoring system, and is connected to the monitoring system through RS485 cable to acquire data of the analyzer or the module.
As shown in fig. 3, an embodiment of the present invention provides a rainwater monitoring method, which can be applied to the plant rainwater monitoring system, and includes steps S100 to S300:
and S100, acquiring rainfall.
Specifically, it is obtained by a rain gauge, and the amount of rainfall characterizes whether there is rainfall.
S200, when rainfall represents that rainfall exists, detecting the rainwater flow of a rainwater outlet of the plant area.
In the embodiment of the invention, the rainwater flow rate indicates whether rainwater flows.
It should be noted that the rainfall characterization may include at least one of the following modes (1), (2), and (3):
(1) when the rainfall reaches the minimum resolution of the rain gauge.
Alternatively, the minimum resolution of the rain gauge is adaptively changed according to different rain gauges, and the minimum resolution is the highest accuracy that can be detected, for example, the minimum resolution of the rain gauge of the embodiment of the present invention is 0.1mm, and when the rainfall reaches (initially reaches) 0.1mm, it is considered that there is rainfall and is a part of the early rainfall (specifically, the early rainfall). It should be noted that, because a large amount of volatile organic gases exist in the air of the industrial plant area, and various pollutants such as grease, heavy metals, solid waste particles and the like also exist on the ground surface, the initial rainwater is most likely to contain a large amount of the above-mentioned objects and is regarded as non-point source pollution, and is not suitable for being directly discharged from the plant area through a pipeline, so the importance of the judgment of the initial rainwater and the water quality analysis monitoring is high.
(2) When the rainfall reaches the rainfall threshold.
It should be noted that the rainfall threshold may be set as needed, and in the embodiment of the present invention, the rainfall threshold is exemplarily illustrated as 20 mm. Specifically, when the rainfall amount ranges from 0.1mm to 20mm, the rainwater can be considered as early-stage rainwater (specifically, another part of the early-stage rainwater) when the monitoring system performs water quality analysis, and when the rainfall amount reaches a rainfall threshold value of 20mm (for example, above the rainfall threshold value), it is considered that rainfall exists and the rainfall is in a middle and late stage.
(3) When the rainfall reaches the rainfall threshold, the rainfall threshold is increased every time the rainfall is increased.
Specifically, after the rainfall reaches the rainfall threshold value of 20mm, the water quality analysis of the rainwater in the middle and later periods can be performed for the Nth time through the monitoring system for the rainfall in the middle and later periods, and the monitoring system is started to perform the water quality analysis once when the rainfall increases by 20mm, so that the analysis is regarded as the (N + 1) th time analysis of the rainwater in the middle and later periods (N is more than or equal to 1).
S300, when rainfall represents that rainfall exists and rainwater flow represents that rainwater flows, controlling a monitoring system to start, and analyzing the water quality of the rainwater at the rainwater outlet through the monitoring system.
It should be noted that, the indication of the rainfall indicates whether there is rainfall, which refers to one of the conditions of real rainfall, when the indication of the rainfall indicates that the rainfall reaches one of the conditions of real rainfall, and when the indication of the rainfall indicates that there is rainfall and the flow of rainwater indicates that rainwater flows, it is determined that there is real rainfall (or the rainfall reaches a degree that the monitoring system can effectively analyze the water quality), that is, it is required to simultaneously satisfy two conditions of the indication of the rainfall and the flow of rainwater, that there is rainfall, and it is determined that there is real rainfall (or the rainfall reaches a degree that the monitoring system can effectively analyze the water quality), so as to start the monitoring system, and perform the water quality analysis on the rainwater at the rainwater outlet through the monitoring system. For example, the degree of rainfall to which the monitoring system can effectively perform water quality analysis includes, but is not limited to, effective data indicating that the monitoring unit can measure rainwater at the rainwater discharge outlet.
Specifically, in step S300, the rainwater at the rainwater outlet is analyzed by the monitoring system, which includes steps S310 to S320:
and S310, analyzing the rainwater at the rainwater outlet through the monitoring unit.
Optionally, turbidity of rainwater at the rainwater outlet is measured in real time by a turbidity analysis module, the pH value of the rainwater at the rainwater outlet is measured in real time by a pH analysis module, and the temperature of the rainwater at the rainwater outlet is measured in real time by a temperature module. Optionally, the turbidity, the ph value and the temperature generated by the monitoring unit constitute the analysis data/analysis result obtained after the analysis.
S320, preprocessing the rainwater at the rainwater outlet, and analyzing the preprocessed rainwater through a COD analyzer.
Optionally, step S320 includes steps S3201-S3203:
s3201, emptying rainwater in the pretreatment water tank and the sampling water tank.
If the analysis of the initial rainwater is currently performed or the analysis of the middle and late rainwater is performed for the nth time, the rainwater in the pretreatment water tank and the sampling water tank may be emptied without performing the steps S3202 to S3203.
It should be noted that in the embodiment of the present invention, for example, when rainwater is stored in the pretreatment water tank and the sample injection water tank, and at this time, water quality analysis of initial rainwater needs to be performed, or the analysis is shifted from the analysis of initial rainwater to the analysis of middle and later rainwater, or the analysis is shifted from the analysis of the middle and later rainwater of the nth time to the analysis of the middle and later rainwater of the N +1 th time, rainwater in the pretreatment water tank and the sample injection water tank needs to be emptied. Specifically, switch on through controlling first valve A2 and second valve B2 and carry out the rainwater unloading, then control first valve A2 and second valve B2 behind the rainwater unloading and cut for the rainwater of the rainwater drain outlet of new collection can be stored in the preliminary treatment water tank, can store in advance a kind water tank after making the rainwater of new collection through preliminary treatment water tank preliminary treatment, in order to carry out the water quality analysis of current rainwater. Optionally, the rainwater emptying can be performed according to a preset corresponding time length, and the emptying is considered to be completed when the time length is reached, so that the first valve A2 and the second valve B2 are controlled to be cut off.
S3202, pretreating the rainwater at the rainwater outlet through a pretreatment water tank, and storing the pretreated rainwater through a sample injection water tank.
S3203, analyzing the pretreated rainwater in the sample injection water tank through a COD analyzer.
Specifically, the COD analyzer analyzes the pretreated rainwater in the sample injection water tank to obtain a COD analysis result, the COD analysis result and the analysis data form a water quality analysis result, the water quality analysis result is transmitted to the data concentration module, and the water quality analysis result is transmitted to the online platform through the data concentration module to be monitored by related personnel.
