Final treatment device for wastewater of high-concentration hardly decomposable organic matter, system using the device, and final treatment method for wastewater of high-concentration hardly decomposable organic matter

摘要

Discharge of high-concentration hard-to-decompose organic substances that enables treatment of hard-to-decompose organic substances and further nitrogen-fixed substances such as ammonium sulfate, ammonium, nitrite, or nitrate nitrogen and that does not require running costs. A final processing apparatus, system, and method are provided. SOLUTION: Decomposition reaction treatment with ozone microbubbles and / or nanobubbles and ozone gas, free radicals generated by crushing of ozone microbubbles and / or nanobubbles and ozone microbubbles, and hardly decomposable organic substances and organic substances such as acrylics It is configured to include a catalytic reaction process for reacting with a microfine solid substance under an activated carbon catalyst.
