Embodiment 1

[0021] Such as figure 1 As shown, the present invention discloses a microbial fuel cell type three-dimensional combined ecological floating bed device, which combines a combined ecological floating bed with a microbial fuel cell. The upper layer and the middle layer are fixed lower metal trays 5, the upper layer aquatic plant unit is composed of floating aquatic plants 1 and conductive materials 2 for fixing floating water plants, and the middle layer aquatic plant unit is composed of submerged aquatic plants 3 and fixed submerged aquatic plants 3 is made of lightweight silk screen 4; the conductive material 2 is led out of the device through a wire 6 connected to an external circuit load 7 to form a microbial fuel cell air cathode electrode; The anaerobic environment forms an anaerobic reduction reaction zone to constitute the anode electrode of the microbial fuel cell. The floating aquatic plant 1 is water spinach. The conductive material 2 is made of activated carbon felt...

Embodiment 2

[0024] It is basically the same as Example 1, except that the floating aquatic plant 1 is cress. The conductive material 2 is made of living stainless steel wire mesh. A group of 4 cm round holes are opened on the conductive material 2 to fix the floating aquatic plants 1 . The submerged plants are hornworts. The lightweight screen 4 is made of polyamide chemical synthetic fiber material. The wire 6 is a copper wire. The metal tray 5 is made of stainless steel.

Embodiment 3

[0026] The floating aquatic plant 1 is calamus. The conductive material 2 is made of carbon cloth. A group of 4 cm round holes are opened on the conductive material 2 to fix the floating aquatic plants 1 . The submerged plants are foxtail algae. The lightweight screen 4 is made of polyamide chemical synthetic fiber material. The wire 6 is a titanium wire. The metal tray 5 is made of stainless steel.

Abstract

The invention discloses a microbial fuel cell type three-dimensional combined ecological floating bed device. The device is formed by combining a combined ecological floating bed and a microbial fuel cell; the combined ecological floating bed comprises an aquatic plant unit arranged at the upper layer, an aquatic plant unit arranged at the middle layer and a metal pallet arranged at the lower layer and used for fixing the upper layer and the middle layer, and a conductive material is led out of the device through a lead connected with an external circuit load, thus an air cathode electrode of the microbial fuel cell is formed; and an anaerobic reduction reaction region is formed by the metal pallet by means of an anaerobic environment of sediments, thus an anode electrode of the microbial fuel cell is formed. The invention also discloses an application of the device. By using the device, the polluted bottom mud is degraded fundamentally, meanwhile, the energy is recovered, and pollutants in a water body are simultaneously degraded, so that the pollutant dissolution equilibrium effect between the bottom mud and the water body is weakened, and the device is suitable for large-scale, modeled and mechanized operation.

Description

technical field [0001] The invention belongs to the field of energy and environmental restoration, in particular to an MFC (Microbial Fuel Cell, microbial fuel cell) type three-dimensional combination ecological floating bed device and its application, which are suitable for the joint purification of shallow surface water bottom mud and water body and recovery of electric energy and biomass energy . Background technique [0002] Nowadays, people pay more and more attention to the control and remediation of water pollution, and the remediation of sediment pollution is even more important. Pollutants are adsorbed, complexed, flocculated, and settled by water particles and deposited in the sediment. After the external pollution is effectively controlled, these pollutants in the sediment may still cause "secondary pollution" to the water body, which will seriously affect Remediation and prevention of water pollution. Studies have shown that the pollutants contained in the poll...
