<p><P>PROBLEM TO BE SOLVED: To provide a wastewater treatment apparatus which can improve the treatment efficiency of nitrogen wastewater containing hydrogen peroxide, and realize compactification and reduction of a running cost. <P>SOLUTION: In the wastewater treatment apparatus, the nitrogen wastewater containing hydrogen peroxide is treated with micro-nano bubbles in a micro-nano bubble reaction tank 18, increasing the activity of microorganisms in the following denitrification tank 3 and nitrification tank 11 to improve the treatment efficiency by the microorganisms, which enables a size reduction of the denitrification tank 3 and nitrification tank 11. As a result, the wastewater treatment apparatus can improve the treatment efficiency of the nitrogen wastewater containing hydrogen peroxide to reduce the initial cost and running cost for the wastewater treatment. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
