Online monitoring and early warning and real-time treatment system and method for heavy metal pollution in farmland

Abstract

The invention provides an online monitoring and early warning and real-time treatment system and method for heavy metal pollution in a farmland. The system comprises online heavy metal monitoring and early warning equipment, a real-time heavy metal treatment device, a heavy metal pollution monitoring platform and a control treatment unit. The field online monitoring and early warning and real-time heavy pollution treatment processes are combined, and the system has the characteristics of rapidness and simplicity in test, accurate result, low cost, low detection limit and high sensitivity, is not destructive on the sample, is capable of greatly shortening the detection period and is suitable for online field detection of the heavy metal content and real-time treatment of the heavy metal pollution. The requirements on professional skills of operators are reduced, and a technical target for integrally performing online monitoring and early warning and real-time treatment on the heavy metal pollution in the farmland is achieved. Moreover, according to the system, the concentration of a certain heavy metal in an area can be measured, the total heavy metal pollution degree in the area can also be measured, the testing sensitivity is high, and any heavy metal content can be simultaneously detected.

Description

technical field [0001] The invention relates to the technical field of heavy metal pollution treatment, and more specifically, to an on-line monitoring, early warning and real-time processing system and method for heavy metal pollution in farmland. Background technique [0002] In recent years, the phenomenon of heavy metal pollution in soil has become increasingly serious, mainly due to factors such as excessive and illegal discharge of industrial production, random dumping of urban sewage and domestic garbage, sewage irrigation in agricultural production, and unreasonable use of pesticides and fertilizers. Pollutants enter agricultural soils in a number of ways. However, heavy metals are difficult to degrade and easy to accumulate. The heavy metals accumulated in the soil are not easy to be leached with water, and are not easy to be degraded by microorganisms. They will enter the crops with the absorption of plant roots and affect the growth and development of crops. Afte...
