Anaerobic treatment equipment and anaerobic treatment system

Abstract

The object of the present invention is to provide an anaerobic treatment apparatus and anaerobic treatment system that enables improved treatment efficiency by maintaining or improving the stirring efficiency inside the tank when performing anaerobic treatment using a carrier-type anaerobic treatment tank. [Solution] To solve the above problems, an anaerobic treatment apparatus and an anaerobic treatment system equipped with this anaerobic treatment apparatus are provided, comprising a carrier-type anaerobic treatment tank and a contact member provided inside the anaerobic treatment tank and in contact with the carrier, wherein the contact member is fixed to the side wall of the anaerobic treatment tank so as to span horizontally between any two points on the inner circumference of the anaerobic treatment tank. According to the present invention, it is possible to improve the stirring efficiency in the anaerobic treatment tank, and consequently, an appropriate shear force is applied to the carrier. This makes it possible to release gases contained within the biofilm and detach attached carriers while suppressing damage to the carrier, thereby improving treatment efficiency.
