Abstract

The invention discloses a microalgae culture- and microbial fuel cell-coupled integration system and a method. The microalgae culture- and microbial fuel cell-coupled integration system comprises an upper cover board, a lower cover board, an outer cylinder, an inner cylinder, a liquid inlet, an air outlet, a waste water outlet and a waste water inlet. The microalgae culture- and microbial fuel cell-coupled integration system is characterized in that the inner cylinder is arranged in the outer cylinder; a space between the inner wall of the outer cylinder and the outer wall of the inner cylinder is taken as a microalgae culture chamber; a microalgae culture medium is arranged in the microalgae culture chamber; meanwhile, the microalgae culture chamber is also taken as a cathode of the microbial fuel cell; the wall surface of the inner cylinder is arranged in a hollow-out manner; an anion-exchange membrane and a cation exchange membrane are alternately arranged on the hollow-out wall surface; a cell cathode is arranged on the outer side of the wall surface of the inner cylinder; and a battery anode is arranged in the inner cylinder. The microalgae culture- and microbial fuel cell-coupled integration system can be widely applied to the fields such as chemical industry, biology and environmental protection.

Description

technical field [0001] The invention relates to an integrated system, in particular to an integrated system and method for coupling microalgae cultivation and microbial fuel cells. Background technique [0002] With the rapid development of my country's economy, the urban population has increased dramatically, which not only greatly increases the demand for energy, but also poses a great threat to the ecological environment due to the discharge of toxic and hazardous waste. According to the 2013 Environmental Status Bulletin of the Ministry of Environmental Protection, the total national energy consumption in 2013 was 3.75 billion tons of standard coal, of which coal consumption accounted for 66.0% of the total energy consumption, and oil consumption accounted for 19.4%. The use of fossil fuels has caused a large amount of harmful smoke emissions. In 2013, the main pollutant CO in the exhaust gas 2 , SO 2 And the total emission of nitrogen oxides is more than 50 million to...
