specific Embodiment approach 2

[0044] Specific embodiment two: this embodiment is different from specific embodiment one: the activated carbon carrier inside the fluidized bed (2) is 0.5-1mm, and a layer of biofilm will be formed after the microbial activated carbon surface grows, and its particle size will change big. Other structures and connections are the same as in the first embodiment.

[0045] Activated carbon and activated sludge are separated at the beginning, and the particle size of activated carbon particles is 0.5-1mm. After the device is officially started, biofilm will adhere to the surface of activated carbon particles, so the particle size will become larger.

specific Embodiment approach 3

[0046] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the materials of the cathode and the anode are mostly carbon rods, steel mesh, titanium mesh, etc., the aperture size is 2-8mm, the shape of the cathode is sheet, and the anode The shape is cylindrical. Other structures and connections are the same as in the first embodiment.

Abstract

The invention discloses an anaerobic fluidized bed series constructed wetland type microbial fuel cell device and method. The anaerobic fluidized bed series constructed wetland type microbial fuel cell device comprises an anaerobic fluidized bed and a constructed wetland type microbial fuel cell which are connected in series; the anaerobic fluidized bed cultures a carrier to which a biofilm is attached as an anode of the constructed wetland type microbial fuel cell. Compared with a traditional active sludge method, a novel sewage treatment system of the anaerobic fluidized bed and the constructed wetland type microbial fuel cell, provided by the scheme, has the advantages that two devices are connected in series to realize deep treatment of sewage and improve the treatment effect of waterquality; the anaerobic fluidized bed can culture the carrier to which the biofilm is attached, and the carrier is used for the anode of the constructed wetland type microbial fuel cell, so that startof the microbial fuel cell can be accelerated.

Description

technical field [0001] The invention relates to the technical field of water treatment and utilization, in particular to an anaerobic fluidized bed series constructed wetland type microbial fuel cell device and method. Background technique [0002] (1) Energy is an important material basis for human survival and sustainable social development. Fossil fuels have maintained industrial and economic development, but energy consumption has intensified with population growth. Fossil fuels have been unable to meet the needs of rapid population and economic growth. Energy shortages not only limit industrial and economic development, but also cause water pollution. Resource shortage problem. [0003] (2) With the growth of the world's population, the world's water consumption is increasing rapidly, and the problem of water pollution is becoming more and more serious. About 1 billion people in the world cannot enjoy sufficient drinking water. my country has also become one of the 13 ...
