Wastewater treatment equipment, power generation equipment, desulfurization treatment equipment, power generation method and desulfurization method

摘要

PROBLEM TO BE SOLVED: To provide a wastewater treatment apparatus, a power generation apparatus, a desulfurization treatment apparatus, a power generation method and a desulfurization method capable of more efficient energy recovery / utilization or desulfurization treatment as a technique associated with wastewater treatment. To provide. SOLUTION: In a wastewater treatment apparatus for treating water to be treated, in order to solve the above problems, a wastewater treatment apparatus and a power generation apparatus for performing power generation or desulfurization treatment by a reaction using a reducing substance in the water to be treated as an electron donor. , Desulfurization treatment equipment, power generation method and desulfurization method. According to the present invention, by performing power generation or desulfurization treatment by a reaction in which a reducing substance contained in water to be treated is directly used as an electron donor, mass transfer is not hindered by microorganisms, which is efficient. Power generation and desulfurization can be performed. In addition, the wastewater treatment equipment can be downsized as compared with the case where the equipment related to power generation and desulfurization treatment by the microbial fuel cell is separately provided.
