Online agricultural non-point source pollution monitoring system

Abstract

The invention discloses an online agricultural non-point source pollution monitoring system. The online agricultural non-point source pollution monitoring system comprises multiple monitoring stations, a communication network and a monitoring centre; the monitoring stations are arranged in different non-point source pollution points, and used for acquiring sewage in real time, performing water quality analysis, and transmitting water quality analysis data to the monitoring centre through the communication network; a sampling and pre-processing unit, a water quality analysis unit, an illumination unit and a monitoring unit are arranged in the monitoring station; the sampling and pre-processing unit comprises a sampling pump and a filter; the water quality analysis unit comprises a samplingtank and an analyzer arranged in the sampling tank; the analyzer is connected to a control cabinet; a control unit is arranged in the control cabinet; and the control unit is used for controlling theaction of the sampling pump, a water level indicator and the analyzer in the monitoring station and communication with the monitoring centre, and transmitting a water quality analysis result and an illumination condition in the monitoring station and the monitoring information of the monitoring unit to the monitoring centre. By means of the online agricultural non-point source pollution monitoringsystem disclosed by the invention, multi-point online monitoring of agricultural non-point source pollution is realized; the automation degree is high; and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of monitoring systems, in particular to an online monitoring system for agricultural non-point source pollution. Background technique [0002] Agricultural non-point source pollution refers to the water pollution caused by pollutants produced in agricultural production activities entering rivers, lakes, reservoirs, and bays through surface runoff of farmland, drainage of farmland, and underground seepage under the action of precipitation and runoff. The existing agricultural non-point source pollution detection device has a single function and cannot perform regular detection, automatic detection, or long-distance detection. It is inconvenient to use, and the detection process is easily affected by environmental factors. [0003] First of all, it is necessary to sample, analyze and monitor the water sources polluted by agricultural non-point sources, but the water sources are seriously polluted, so the water...

The existing agricultural non-point source pollution detection device has a single function and cannot perform regular detection, automatic detection, or long-distance detection. It is inconvenient to use, and the detection process is easily affected by environmental factors.

[0003] First of all, it is necessary to sample, analyze and monitor the water sources polluted by agricultural non-point sources, but the water sources are seriously polluted, so the water sources should be simply filtered before sampling and analysis; Both the process and the result are inconvenient; when some are filtered, due to the use of chemical or biological filtration, not only the filtration process is complicated and the cost is high, but also the analysis characteristics of the water source are destroyed, which affects the final monitoring results

[0004] Among the sampling pools used in the monitoring system, the existing sampling pools have poor sealing performance, which can easily affect the analysis results, and are inconvenient to clean. The instruments used for monitoring and analysis cannot be conveniently fixed on the sampling pools. The installation of the instruments takes time and effort. inconvenient

Publication number CN 106226486 discloses an online automatic monitoring system for water pollution sources. It adopts data communication methods (network, mobile phone) to receive monitoring data and historical data reported by data acquisition instruments. Based on online monitoring of pollution sources, it meets the needs of environmental supervision and environmental monitoring. ; Before monitoring the polluted water source, there is no pretreatment of the water source, and multi-point monitoring cannot be realized
