Heavy metal sensing and monitoring apparatus

Abstract

The invention provides a heavy metal sensing and monitoring apparatus, and belongs to the field of water pollution monitoring and treatment. The heavy metal sensing and monitoring apparatus comprises a microbiological fuel cell, which comprises an anode chamber, a cathode chamber and a proton exchange membrane (PEM) for separating the anode chamber and the cathode chamber, wherein the anode chamber comprises an anode, microorganisms and organic matters; the cathode chamber comprises a cathode, heavy metal cations and an optionally existed cathode catalyst; the anode and cathode are connected to double terminals of an external resistor through circuits, and the circuits are also connected to a data acquisition apparatus.

Description

technical field [0001] The invention relates to a heavy metal sensing and monitoring device, which belongs to the field of water pollution monitoring and treatment. Background technique [0002] Ecology and the environment are one of the major issues of people's livelihood. Rapid urbanization has put forward higher requirements for the monitoring of wastewater discharge and the improvement of the water quality of polluted rivers. Among them, environmental pollution related to heavy metals, especially water pollution, is Shenzhen and even the whole country. solved problem. There are about 45 kinds of heavy metals, such as copper, lead, zinc, manganese, cadmium, mercury, gold, silver and so on. Although manganese, copper, zinc and other heavy metals are trace elements needed for life activities, most heavy metals such as mercury, lead, cadmium, etc. are not necessary for life activities and are important components of environmental endocrine disruptors and drinking water sour...

AI Technical Summary

Problems solved by technology

[0005] However, the existing heavy metal on-line monitoring equipment has certain limitations in practice. For example, some imported products are not only expensive, but also difficult to apply to the national conditions of the country, such as high concentration of wastewater, complex composition and difficult system maintenance technology, etc. , poor applicability; the shortcomings of domestic products include the stability of the instrument, the inability to monitor multiple parameters at the same time, and the detection limit of certain items such as mercury are too high, etc.

Moreover, most instruments cannot meet the requirements of long-term and continuous monitoring of heavy metal content in high-concentration wastewater
