Magnetoelectricity strengthened anaerobic bioreactor

Abstract

The invention discloses a magnetoelectricity strengthened anaerobic bioreactor which comprises a barrel body; the lower end of the barrel body is connected with a water inlet pipe; a plurality of iron-nickel bimetallic rods are vertically fixed to the barrel body; the upper end of the barrel body is provided with a gas-liquid separator; a gas outlet is formed above the gas-liquid separator; a water outlet is formed in the side edge of the barrel body and between the lower side of the gas-liquid separator and the upper side of the iron-nickel bimetallic rods; a plurality of permanent magnets are fixed at the lower end of the inner side of the barrel body. For the magnetoelectricity strengthened anaerobic bioreactor, by utilizing the current function generated by bimetallic corrosion, a microorganism function is strengthened, microcurrents can be generated to stimulate growth of microorganisms, and better pollutant treatment effect is obtained; meanwhile, iron ions produced with corrosion can strengthen the microorganism decomposition effect, so that the anaerobic time is greatly shortened, and the equipment investment and the occupying area can be reduced.

Description

technical field [0001] The invention relates to a magnetoelectric enhanced anaerobic bioreactor, which belongs to the technical field of sewage treatment in environmental protection. Background technique [0002] With the rapid development of my country's economy, my country's water environment problems have become increasingly prominent, and urban and rural water environments have encountered unprecedented threats. If a survey shows that more than 90% of the rural water ecology in the Yangtze River Delta region has lost its basic functions, urban and rural rivers have been severely degraded due to pollution and ecosystems, the water quality of the rivers has basically been in the V class or inferior to the V class, and most of the rivers are seriously polluted and rich. Nutritization, lack of oxygen in the water body, turning black and smelly, resulting in a severe environmental and ecological situation. Therefore, vigorously improving the water quality of discharged sewag...

Problems solved by technology

With the increasing shortage of energy in the world, the requirements for energy saving and emission reduction are increasing. The reduction of water consumption makes the concentration of discharged wastewater higher and higher, and the unit pollution load is increasing. At the same time, due to the increasingly complex types of pollutants in wastewater , Relying solely on aerobic biological treatment is far from meeting the needs of wastewater treatment. Anaerobic biological treatment technology has many advantages such as low investment, low energy consumption, recyclable biogas energy, high load, less mud production, and impact load resistance. Attention and research by people in the environmental protection circles, great progress has been made in basic research such as anaerobic microbiology and biochemistry, and a variety of new anaerobic bioreactors have emerged
