The technical scheme of the invention is further described in detail below with reference to the accompanying drawings and examples.
Embodiment 1, as shown in fig. 1, is a miniature water quality early warning method, comprising the following steps:
s1, searching construction points: and (5) on-site investigation of important drainage ports or sections, and selection of construction points of the early warning stations.
When the key drainage or section is surveyed on site, the drainage information of the river can be used for conducting investigation and tracing, and the investigation work can be conducted through the technical means of manual on-site investigation, satellite remote sensing, unmanned aerial vehicle aerial photography, unmanned ship monitoring, underwater robot detection and the like, so that the drainage distribution condition in the area can be cleared.
When the construction point of the early warning station is selected, the following principle is mainly considered:
1) The drainage is large, and the drainage of main pollution sources, or the drainage of enterprises and public institutions of special pollutants with important attention, the drainage of sewage centralized treatment facilities, and the like.
2) The water environment problem is prominent, such as the drainage ports near the water quality section, such as the drainage ports at the upstream and downstream of the river reach with the water quality section exceeding the water quality index.
3) Attention is paid to the discharge port of a region with high requirements on the quality of water environment, such as a pollution source discharge port at the upstream of a reservoir, and the water pollution risk of a drinking water source is controlled and controlled.
4) Important examination sections such as a city test, a national test or a village and town are monitored in real time and data support is provided for manually calculating the pollution source concentration of the section.
S2, monitoring in real time: and (5) monitoring the water quality, the water quantity and the video of the key drainage port or the section in real time.
The adopted water quantity real-time monitoring device is any one of a Doppler ultrasonic flowmeter and an electric wave radar flow rate meter for monitoring, and the section flow rate is obtained through the measured flow rate, water level and section size.
The Doppler ultrasonic flowmeter comprises a flow rate sensor, a pressure sensor and a temperature sensor which are respectively used for measuring the speed, the water depth, the fluid temperature and the sound speed compensation of the fluid flow. The method is suitable for measuring dirty water and slurry with more impurities, such as urban sewage, sludge and the like. The Doppler ultrasonic flowmeter is arranged at the downstream of a straight section of the channel with a fixed section, and the length of the straight section is 15-20 times of the hydraulic radius of the channel.
The radar flow velocity meter adopts Doppler principle to detect the flow velocity of water flow in non-contact mode, and is installed above water bodies such as rivers, channels and the like along the direction of the included angle of the water surface of about 45-60 degrees. The device can be used for monitoring the water flow surface flow velocity of river channels, open channels and underground sewage disposal wells.
After the flowmeter is installed, the cable, the solar panel power supply system and the communication interface are confirmed to be normally connected, the starting software starts to automatically monitor the discharge flow, and the flow data are displayed in an instantaneous flow value and an accumulated flow value.
The real-time monitoring indexes of the water quality comprise pH, conductivity, dissolved oxygen, turbidity, temperature, COD, ammonia nitrogen, total nitrogen and total phosphorus. Other indexes can be expanded according to the requirements of users, and the measuring range can be calibrated according to the actual conditions of the water area. The water quality monitoring method adopts any one of a hyperspectral method and an electrode method for monitoring.
The hyperspectral technology is one of remote sensing technologies, ultraviolet-visible light-near infrared active light sources in the range of 200nm-2500nm are used for irradiating detection water, light signals reflected by water substances are received through a detector, the spectral information of the substances is collected through the spectroscopic technology, and the composition and content change trend of the water substances are reflected through the energy values of each wave band. The hyperspectral method separates the detection water body from the detector, realizes a non-contact detection technology, does not have chemical reagents, greatly reduces energy consumption and secondary pollution, and realizes green ecological monitoring.
The electrode method is one of the sensing technologies, and only the sensor is needed to be put into the water sample to be detected, and no sample pretreatment or sample transmission is needed.
Before monitoring, starting the water pump, synchronously starting the water outlet, automatically cleaning the water collecting pipeline, cleaning for 1 minute, and closing the electromagnetic valve of the water outlet after cleaning to start water storage in the water tank. When the water quantity exceeds the water gap, triggering a water level probe of the water gap, and after confirming that the water level requirement is met, commanding the water pump to be closed to stop water collection. The monitor is started according to the set monitoring period (30 minutes/time) to detect.
The video monitoring adopts a 360-degree rotatable camera with a face recognition function, and the monitoring range covers 20 meters around the river inlet and the river outlet. The video monitoring has a face recognition function, and when information except the pre-recorded face information appears in the monitoring range, warning information can be sent, and video monitoring images and the warning information are sent to the management platform through a wireless transmission network.
