Non-point source pollution online monitoring and early warning method in county territory

Abstract

The invention discloses a non-point source pollution online monitoring and early warning method in a county territory. The non-point source pollution online monitoring and early warning method includes the following steps that step one, multi-environment monitoring is performed; step two, monitoring data summary transmission is performed; step three, a remote monitoring center is set up; step four, information management and decision is performed; in the step 1, multi-environment monitoring includes the following steps of establishing an outdoor water quality monitoring station, establishing afarmland runoff monitoring station, establishing a microclimate monitoring station, establishing a soil moisture monitoring station and establishing a hydrological monitoring station. The non-point source pollution online monitoring and early warning method combines the Internet of Things, big data and a GIS geographic information system with non-point source pollution, the development of non-point source pollution modeling is accelerated, and the quantitative and precise trend of non-point source pollution is promoted; the monitoring intensity and early warning capability of non-point sourcepollution are greatly improved, and feasible methods and means for solving the increasingly prominent contradiction between economic development and water resources are provided.

Description

technical field [0001] The invention relates to the technical field of non-point source pollution, in particular to an online monitoring and early warning method for non-point source pollution in the county area. Background technique [0002] Today, non-point source pollution has become one of the three major environmental pollutions in my country, and it is also a serious environmental problem of common concern to the world. Non-point source pollution is that dissolved and solid pollutants flow into receiving water bodies (including rivers, lakes, reservoirs and bays, etc.) Eutrophication or other forms of pollution of water bodies. It is mainly composed of soil and sand particles on the surface, nutrients such as nitrogen and phosphorus, harmful substances such as pesticides, solid waste such as straw and agricultural film, manure and sewage from livestock and poultry farming, bait and drugs from aquaculture, rural domestic sewage and garbage, and various atmospheric part...

AI Technical Summary

Problems solved by technology

[0003] Compared with point source pollution, non-point source pollution has the following characteristics: (1) strong randomness; (2) significant spatial and temporal differences in pollution load; (3) large source area of ​​pollutants; Deep, difficult to research, control and manage
