Abstract
The invention discloses an ecological floating bed-sediment microbial fuel cell coupled device for water body remediation, belonging to the technical field of natural water body remediation. Accordingto the invention an ecological floating bed is coupled with a sediment microbial fuel cell; the ecological floating bed comprises an ecological floating bed body and an ecological floating bed frame,and the upper part of the ecological floating bed body is provided with ecological floating bed plants; the sediment microbial fuel cell comprises an ecological floating bed substrate which simultaneously functions as a negative electrode and an ecological floating bed plant substrate, and the ecological floating bed substrate is arranged in a substrate fixing net connected with the ecological floating bed and is internally provided with a current collector; and the current collector is connected with a positive electrode through a resistor, and the positive electrode is buried in the sediment of a water body. The ecological floating bed-sediment microbial fuel cell coupled device of the invention removes pollutants from a water body and treats the sediment through the sediment microbialfuel cell, so the device effectively solves the problem of endogenous pollution of the water body, thoroughly treats water body pollution, and has significant environmental and economic benefits.
Description
technical field [0001] The invention belongs to the technical field of restoration of natural water bodies, and in particular relates to a device for restoring natural water bodies by coupling an ecological floating bed with a sedimentary microbial fuel cell. 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 rivers, lakes and other water bodies. Excessive use of chemical fertilizers and pesticides in agriculture, along with the runoff of rainwater into water bodies, has now accumulated a large amount of pollutants such as nitrogen, phosphorus, heavy metals, and persistent organic compounds in water bodies, posing a huge threat to people's living and production water. [0003] At th...
