Farmland non-point source pollution surface runoff monitoring device and method

Abstract

The invention provides a farmland non-point source pollution surface runoff monitoring device and method. The device comprises water volume sensors, a wireless measure and control module and a remote receiving module, wherein the water volume sensors are arranged at the outlets of runoff collection pipes of all surface runoff monitoring communities; the runoff collection pipes are communicated with runoff collection tanks of the surface runoff monitoring communities, and used for acquiring the surface runoff data of each surface runoff monitoring community, and sending the acquired surface runoff data to the wireless measure and control module; the wireless measure and control module is used for receiving the surface runoff data sent by the water volume sensors, and sending the received surface runoff data to the remote receiving module; the remote receiving module is used for receiving the surface runoff data sent by the wireless measure and control module. Through the adoption of the device, automatic monitoring of surface runoff and remote transmission of monitored runoff data can be realized, and the monitoring result is more accurate.

Description

technical field [0001] The invention relates to the technical field of farmland non-point source pollution monitoring, in particular to a device and method for monitoring surface runoff of farmland non-point source pollution. Background technique [0002] At present, the loss of farmland nutrients into the environment has caused many problems such as eutrophication of surface water, excessive nitrate in groundwater, reduction of farmland production capacity, and decline of ecological environment quality. It is imperative to protect the water quality of water bodies and reduce the migration of farmland pollutants to water bodies. Only by monitoring farmland non-point source pollution and clarifying its occurrence process and development characteristics under different conditions can we formulate targeted non-point source pollution prevention and control strategies . At present, the devices and methods generally used for surface runoff monitoring of farmland non-point source ...

AI Technical Summary

Problems solved by technology

[0004] In view of this, how to overcome the current problems such as the inability to monitor the surface runoff volume of non-point source pollution in farmland in real time and the large error of monitoring results has become a technical problem that needs to be solved at present.
