Embodiment 1

[0018] Such as figure 1 and 2 As shown, a box made of PVC material with an upper end opening is fixed on the graphite electrode plate 1. The side of the box close to the graphite electrode plate is the graphite electrode plate as its side. The shape of the box is preferably one with a wide opening and a small bottom. shape, it is convenient to insert in the bottom mud, it is preferably a wedge-shaped box 4 (its side longitudinal section is triangular, figure 1 ) or trapezoidal box 2 (its side longitudinal section is trapezoidal, figure 2 ).

[0019] Such as image 3 and Figure 4 As shown, three graphite electrode plates (20cm×30cm, Figure 4 A) in parallel and connected with the same electrode lead A 3 ( Figure 4 The physical picture in A), use waterproof glue to protect the connection. Insert the graphite electrode plate 1 and the wedge-shaped box 4 into the bottom mud of a river in Guangzhou until the bottom mud covers the upper opening of the box and fills up the ...

Abstract

The invention discloses a method for acquiring an in-situ bottom mud sample from a bottom mud type fuel cell. A box with an opening at the upper end is fixed on the surface of a hard electrode plate;one surface, close to the electrode plate, of the box uses the electrode plate as a side surface; the hard electrode plate with the box is inserted into the bottom mud, so that the bottom mud immersesthe box; one end of an electrode wire A is connected with the hard electrode plate, the other end of the electrode wire A is connected with a resistor; one end of an electrode wire B is connected with the resistor, and the other end of the electrode wire B is arranged in upper-layer water, and a bottom mud fuel cell is successfully constructed. After the bottom mud fuel cell runs for set time, the hard electrode plate is pulled out, and an in-situ bottom mud sample immersed in the box is obtained. According to the invention, a bottom mud sample recovery device is fixed on the electrode, can be arranged into mud along with the electrode, and collects bottom mud samples around the electrode. The method provided by the invention is used for realize convenient, effective and low-cost acquisition of the bottom mud sample near the electrode of the bottom mud fuel cell, and a method for researching the performance and the ecological environment effect of the bottom mud fuel cell is provided.

Description

technical field [0001] The invention belongs to the technical field of energy and environmental protection, and in particular relates to a low-cost, simple and effective method for obtaining in-situ sediment samples from a sediment-type fuel cell. Background technique [0002] Energy crisis and environmental pollution have become two important limiting factors for world development. Large amounts of chemical energy are stored in waste and pollutants in the environment. Microbial fuel cells (MFC) can convert the chemical energy in these pollutants into electrical energy, which has the function of "turning waste into energy". [0003] In the MFC, the sediment-type MFC can oxidize and degrade organic matter or pollutants through the respiration and metabolism of microorganisms in the sediment, and directly output bioelectricity. Since this century, sediment-based fuel cells have developed rapidly and are increasingly used in practical environments. At present, the functions ...
