Agricultural non-point source pollution control solutions

1. Overview

With the agricultural production mode changing from extensive to intensive, a large number of chemical fertilizers, pesticides and organic fertilizers are applied to the agricultural production process, making a large number of nitrogen, phosphorus and other non-point source pollutants remain in the farmland, and enter the water through runoff under the action of rainfall, resulting in agricultural non-point source pollution. Agricultural non-point source pollution involves a wide range, strong concealment, large randomness, poor traceability andlong incubation period, which makes it difficult to monitor and control. In China, agricultural non-point source pollution has become an important source of eutrophication.

Therefore, it has become a major problem restricting the sustainable development of agriculture, the safety of ecological environment and the improvement of rural human settlements in China.

Opinions of the Central Committee of the Communist Party of China and the State Council on Deepening the Fight against Pollution, Action Plan for Agricultural and Rural Pollution Control(2021-2025),"14th Five-Year Plan for Soil, Groundwater and Rural Ecological Environment Protection," "14th Five-Year Plan for National Agricultural Green Development,""Implementation Plan for Agricultural Non-point Source Pollution Control and Supervision Guidance (Trial)" and other documents clearly put forward to strengthen the prevention and control of agricultural non-point source pollution.Through the implementation of this project, we can basically master the local farming and freshwater aquaculture.

Such as agricultural non-point source pollution situation and current situation, to provide support for agricultural non-point source pollution prevention and control decision-making.

2. Solution overview

In order to solve the problems of agricultural non-point source pollution involving a wide range, strong concealment, large randomness, poor traceability and long incubation period,our company has developed a brand-new sampling equipment, which can be deployed outdoors according to demand,using solar energy + outdoor maintenance-free battery power supply + video monitoring + Internet of Things platform, which can meet the needs of all-weather uninterrupted sampling at any time. At the same time, the equipment has the function of remote control, and users can collect real/real data at any time according to actual needs on PC or mobile phone.

Effective/representative water samples, great convenience for users, saving sampling costs and time.
