Apparatus for high-rate upflow treatment of wastewater using two-phase anaerobic reactors and method to treat wastewater using thereit

摘要

In the present invention, in the anaerobic wastewater treatment apparatus, the wastewater to be treated is introduced, an acid-producing reaction of a high concentration of organic matter in the wastewater is performed, and the sulfate of the sulfate in the wastewater is not inhibited so as not to inhibit the formation of methane at a later stage during the introduction of a high concentration of sulfate. An upflow anaerobic acid production reactor having means for discharging the sulfide produced by reduction to the outside (H ₂ S); And an upflow anaerobic methane production reactor, in which the sulfate concentration is lowered and the organic acid is generated, and the methane generation reaction of the wastewater is performed. An anaerobic wastewater treatment apparatus and a wastewater treatment method using the same are disclosed. In the apparatus and the method, in the acid production reactor and the methane production reactor, it is preferable that a media-free upflow granular sludge process is performed. According to the abnormally high efficiency upflow anaerobic wastewater treatment apparatus of the present invention and the wastewater treatment method using the same, it is possible to efficiently treat the high-degradability, particularly the hardly degradable wastewater including sulfate, to prevent the deterioration of methane-producing bacteria by the sulfate. In addition, it achieves the effect of effectively treating high quality methane gas (more than 80%) and high concentration organic materials.;Anaerobic, Wastewater Treatment, Acid Production Reactor, Methane Production Reactor, Methane Gas, Highly Concentrated Organic Wastewater
