Plant-SMFC system for electricity generation and algae-rich water body remediation and application equipment thereof

Abstract

The invention discloses a plant-SMFC system for electricity generation and algae-rich water body remediation and application equipment thereof. Plants in the system are hydrilla, the system comprisesa cathode and an anode which are made of graphite materials, the anode is located in bottom mud of a water body, the cathode is located in overlying water, a resistor is electrically connected betweenthe cathode and the anode, and the resistor is connected with an external electric appliance in parallel. The bottom mud contains sedimentary algae, and compared with other plants, the hydrilla can obviously enhance electricity generation capacity of the SMFC, so that a better synergistic effect is achieved. The equipment for planting the hydrilla can bring hydrilla seedlings to the surface of underwater bottom mud, the roots of the hydrilla seedlings can be inserted into the bottom mud, rapid and large-area hydrilla seedling planting is achieved, the difficulty of hydrilla seedling plantingis reduced, the roots of the hydrilla seedlings are inserted into the bottom mud, upward floating of the hydrilla seedlings is avoided, and the survival rate of the hydrilla seedlings is increased.

Description

technical field [0001] The invention relates to the technical field of black algae planting, in particular to a plant-SMFC system and its application equipment for power generation and algae-rich water restoration. Background technique [0002] With the development of my country's economy, the process of industrialization and urbanization has accelerated, the amount of domestic sewage and industrial wastewater has increased, and a large amount of untreated or substandard wastewater has been discharged into natural water bodies, resulting in the pollution of water bodies such as rivers and lakes. , heavy metals, persistent organic compounds and other pollutants accumulate in large quantities in water bodies, posing a huge threat to people's living and production water; [0003] At the same time, the release of sediment pollution to the water body is also a major concern. Pollutants will migrate and transform between the water body and the sediment. When the external source pol...

Problems solved by technology

[0008] When repairing the bottom mud, it is necessary to plant the black algae in the bottom mud of the water body, and the roots of the black algae need to be inserted into the bottom mud in the water, so that the artificial underwater planting of the black algae will cause inconvenience and increase the risk of planting the black algae. Difficulty in the process, and because the bottom mud (upper bottom mud) close to the water is relatively loose, when the root system of the hydra is inserted into the bottom mud shallowly, it is easy to break away from the bottom mud, so that the hydra is easy to float upwards and the survival rate of the hydra is not high. At the same time In order to install the cathode plate and the anode plate in place while planting black algae, we propose a plant-SMFC system and its application equipment for electricity generation and algae-rich water restoration
