Document Type and Number:
Japanese Patent JP7479998
Kind Code:
B2
Abstract:
To provide a biological nitrification apparatus using a panel water tank with an improved water flow rate for a solid-liquid separator.SOLUTION: A biological nitrification apparatus 402 for groundwater using a panel water tank includes a biological nitrification tank 420 (430). The biological nitrification tank 420 (430) is a circulating flow tank for biological treatment of treated water using nitrifying bacteria carriers 600 (700). The biological nitrification tank 420 (430) has an outflow part for discharging the biologically-treated water out of the tank, and a tubular wedge wire screen (solid-liquid separator 422 (432)) is connected to the outflow part.SELECTED DRAWING: Figure 5
