A constructed wetland device coupled with clustered microbial fuel cells

Abstract

The invention discloses a constructed wetland device coupled with cluster type microbial fuel cells, comprising a wetland cavity, the wetland cavity is divided into two parts, a purification area and a water collection area by a partition, and the bottom of the partition is provided with a connection for connecting the purification area and the collection area. The sink in the water area. A water purification pipeline is arranged in the purification area, and a cluster microbial fuel cell is arranged in the water purification pipeline. There is a water distribution diversion channel connected to the drainage outlet of the water purification pipeline, and the remaining space in the purification area is filled with wetland fillers, and wetland purification plants are planted. The invention has the advantages of simple structure, modular assembly, etc. The multiple filter structures and the rapid replacement structure of the inner casing are beneficial to strengthen the purification efficiency of the system, solve the problem of system blockage, achieve the purpose of reducing the footprint of the wetland, prolonging the service life of the wetland, and realizing artificial Scale engineering application of wetland-microbial fuel cell systems.

Description

technical field [0001] The invention belongs to the field of environmental engineering, in particular to an artificial wetland device coupled with a cluster type microbial fuel cell. Background technique [0002] Compared with traditional centralized sewage treatment systems, constructed wetlands have the advantages of low construction and operating costs, simple maintenance, and good landscapes, and have been widely used in the decentralized treatment of various types of sewage. However, in order to maintain efficient and stable purification efficiency, constructed wetlands often need to occupy a large area of ​​land. [0003] Microbial fuel cells catalyze the decomposition of organic matter by microorganisms at the anode of low potential to generate electrons and protons, and then the electrons pass through the external circuit to the high potential cathode and interact with the electron acceptor (O 2 , NO 2 - and NO 3 - etc.) and protons from the anode combine to deg...
