On-line agricultural non-point source pollution monitoring and automatic sampling system

Abstract

The invention provides an on-line agricultural non-point source pollution monitoring and automatic sampling system and belongs to the field of environmental scientific and farmland ecological research equipment. The system comprises an automatic rainfall amount monitoring subsystem for monitoring rainfall amount and a rainfall process, an automatic flow monitoring subsystem for monitoring agricultural non-point source pollution runoff gathered into a trapezoid weir, an on-line sampling subsystem for obtaining a water sample of the agricultural non-point source pollution runoff from the trapezoid weir, an on-line non-point source pollution index monitoring subsystem for monitoring a preset non-point source pollution index of the agricultural non-point source pollution runoff in the trapezoid weir, a system control and data processing subsystem for acquiring data from the connected subsystem and processing and storing the acquired data, and a solar power supply subsystem which is connected with the system control and data processing subsystem and is used for supplying power to all the subsystems. According to the technical scheme disclosed by the invention, the agricultural non-point source pollution charge and a production process thereof can be automatically sampled and monitored.

Description

technical field [0001] The invention relates to the fields of environmental science and farmland ecology research equipment, in particular to an on-line monitoring and automatic sampling system for agricultural non-point source pollution. Background technique [0002] In the current research work, pollution monitoring can be divided into artificial fixed-point monitoring and automatic monitoring. Fixed-point monitoring is time-consuming and laborious. For special conditions (such as precipitation) or pollution monitoring in special areas, it appears to be lagging behind and powerless. Therefore, automatic monitoring is increasingly becoming the leading role in pollution monitoring, and artificial fixed-point monitoring is used as an auxiliary means. This is the general trend of pollution monitoring work at present. [0003] In automatic pollution monitoring, point source pollution monitoring is the main focus. Because the pollution source is fixed and the pollution dischar...

Problems solved by technology

Therefore, compared with point source monitoring, its monitoring has certain difficulties. At present, there are few automatic monitoring systems for non-point source pollution, or its monitoring methods are not yet mature.
