Wetland soil heavy metal intelligent identification and monitoring device

Abstract

The invention relates to the technical field of soil pollution monitoring in the field of environmental protection, in particular to a wetland soil heavy metal intelligent identification and monitoring device which comprises a reaction cylinder, an electrode assembly is embedded in the top end of the reaction cylinder, and three conductive connecting rods are annularly arranged at the top end of the electrode assembly. A control box is jointly installed at the top ends of the three conductive connecting rods, a wire is embedded in the upper end of the control box, the electrode assembly comprises a cylinder cover, and a working electrode is arranged at the lower end of a third connecting column. Water in a large range can be sucked into the reaction cylinder through the water collecting pipe, and liquid is filtered through the filter membrane layer and the inner filter screen, so that solid impurities entering the reaction cylinder can be effectively reduced, the working electrode can react in the reaction cylinder without external interference, the detection precision is improved, the liquid level sensor is mounted in the cylinder shell, and the one-way electromagnetic valve is mounted below the cylinder shell so that soil can be detected randomly in different time periods.

Description

technical field [0001] The invention relates to the technical field of soil pollution monitoring, in particular to an intelligent identification and monitoring device for wetland soil heavy metals. Background technique [0002] Nowadays, with the development of modern agriculture and science and technology, automatic, intelligent, comprehensive and precise rapid detection of heavy metals in soil technology has become an inevitable trend. The pollution of industrial "three wastes" and the excessive heavy metal content in soil are serious and common. This not only poisons the soil-plant system and reduces the quality of plant species, but also pollutes surface water through runoff and leaching, especially through the food chain, especially After the wetland is polluted, it will have a great impact on the environment and ecology, and many fish and poultry will be affected. Therefore, it is necessary to detect the heavy metal content in the wetland soil. [0003] A Chinese pate...

[0003] A Chinese patent discloses an online monitoring, early warning and real-time processing system for farmland heavy metal pollution (authorized announcement number CN108896737B). This patented technology sends out early warning signals according to the severity of soil pollution; the control processing device is used to receive and analyze early warning signals and issue control instructions; The heavy metal real-time processing device is used to receive control instructions and carry out adsorption treatment on heavy metals, but it is greatly disturbed by the external environment during the monitoring process, resulting in large detection errors and low accuracy
