排水処理装置
Document Type and Number:
Japanese Patent JP6976556
Kind Code:
B2
Abstract:
To provide promotion of transfer of solids to another treatment tank.SOLUTION: The wastewater treatment device includes a plurality of treatment tanks including an anaerobic treatment tank and an aerobic treatment tank on the downstream side of the anaerobic treatment tank, a partition wall partitioning between the anaerobic treatment tank and the aerobic treatment tank, an aerobic treatment tank installed in the aerobic treatment tank, a transfer pump for transferring the water in the anaerobic treatment tank to another treatment tank different from the anaerobic treatment tank and the aerobic treatment tank among the plurality of treatment tanks, and an advection opening forming portion provided on the downstream side of the aerobic treatment tank to form an advection opening for advection of water to the downstream side. The partition wall has one or more first openings and one or more second openings. The size of the advection opening limits the amount of water flowing through the advection opening to a small amount when the amount per unit time of influent water to the wastewater treatment device temporarily increases due to peak inflow. Thus, the water levels of the anaerobic treatment tank and the aerobic treatment tank are temporarily raised.SELECTED DRAWING: Figure 8
