Electricity-assisted anaerobic bioreactor

Abstract

The invention discloses an electricity-assisted anaerobic bioreactor, which comprises a barrel body, wherein the lower end of the barrel body is connected with a water inlet pipe; a plurality of ferrum-nickel bimetal rods are vertically fixed in 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 wateroutlet is formed in the side edge of the barrel body, and is positioned in a position between the lower side of the gas-liquid separator and the upper side of the ferrum-nickel bimetal rods; a plurality of carbon fibers are wound among the plurality of ferrum-nickel bimetal rods. The current effect generated by bimetal corrosion is utilized, the microbe effect is enhanced; micro current can be generated; the micro current is used for stimulating the microbe growth; the good contaminant treatment effect is obtained; meanwhile, ferrum ions generated through the corrosion can reinforce the microbe decomposing effect; the anaerobic time is greatly shortened; the equipment investment and the occupied area can be reduced.

Description

technical field [0001] The invention relates to an electrically assisted 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 sewage ...

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
