Problems solved by technology

Unavoidable, it needs to be carried out in the laboratory, which cannot meet the requirements of real-time monitoring of water bodies and timely feedback of data
Second, the cost of using chemical analysis and instrumental detection is high
Especially for the instrument detection method, the price of the instrument is high and the maintenance cost is high
Furthermore, the current common detection methods have relatively high requirements on the knowledge base of the testers, which limits the application of the detection methods.
Finally, as a simple detection method, the above method cannot achieve the purpose of energy recovery and stable treatment of electroplating wastewater

Embodiment 1

[0038] The MFC toxicity sensor of this embodiment is divided into two parts: a main body and an external circuit. The main body includes a first acrylic component 1, a second acrylic component 2, a third acrylic component 3 and a fourth acrylic component 4 connected in sequence. The first acrylic member 1 has the same structure as the fourth acrylic member 4, the first acrylic member 1 and the fourth acrylic member 4 are cuboids with a length of 1 cm, a width of 8 cm and a height of 8 cm; The structure of the third acrylic member 3 is the same. The outside is a cuboid with a length of 6.8cm, a width of 8cm and a height of 8cm. The corners of -4 are provided with through holes ( figure 1 and figure 2 Not shown in ) for long screw fixing members 1-4; the middle of the second member 2 and the third member 3 is hollowed out as a cylinder. In order to ensure that the cylindrical chambers of the second member 2 and the third member 3 can form a closed space for storing cathode an...

Embodiment 2

[0059] The MFC toxicity sensor adopted in this embodiment has the same structure as that in Embodiment 1, and detects the influent containing only nickel ions (denoted as MFC1), and the influent containing four heavy metal ions of nickel, copper, zinc, and cadmium. Fix the influent concentration of three kinds of heavy metal ions, change the influent concentration of nickel ions (denoted as MFC2), change the influent concentration of three kinds of heavy metal ions, fix the influent concentration of nickel ions (denoted as MFC3). The specific heavy metal concentration gradient details are shown in Table 3.

Abstract

The invention discloses an MFC toxicity sensor and application thereof. The MFC toxicity sensor comprises a body and an external circuit, the body comprises a first component, a second component, a third component and a fourth component which are sequentially connected, a proton exchange membrane is arranged between the second component and the third component, water inlets are formed in the upper surfaces of the second component and the third component, and the external circuit comprises a wire and a resistance box. A titanium wire is connected with the resistance box through a lead to form a loop. The toxicity sensor does not depend on a power supply and an instrument, and the sensor device can move freely and is not constrained by conditions. Therefore, in-situ detection of the nickel element can be realized, information can be conveniently and timely transmitted, and real-time monitoring is facilitated.

Description

technical field [0001] The invention relates to the technical field of new energy and environmental engineering, in particular to an MFC toxicity sensor and its application. Background technique [0002] The current industrial development is rapid, and the accompanying environmental pollution is also becoming more and more serious. As one of the three major industrial wastewaters, the treatment of electroplating wastewater has become a major problem, and metal nickel is the main component of electroplating wastewater. The traditional detection methods of nickel include atomic absorption spectrometry, inductively coupled plasma mass spectrometry, capillary electrophoresis, microprobe and adsorption method, etc. However, these detection techniques are all carried out in the laboratory, the cost is high, and continuous monitoring cannot be realized, and the concentration change cannot be reflected in real time. Microbial fuel cell (MFC) is a water treatment concept that conve...
