FINAL TREATMENT DEVICE OF WASTEWATER CONTAINING HIGH CONCENTRATION OF PERSISTENT ORGANIC MATTER AND SYSTEM USING THE DEVICE AND FINAL TREATMENT METHOD OF WASTEWATER CONTAINING HIGH CONCENTRATION OF PERSISTENT ORGANIC MATTER

摘要

To provide a final treatment device, system, and method of wastewater containing a high concentration of persistent organic matter which enables treatment of the persistent organic matter and also ammonium sulphate and nitrogen fixation matter such as ammonium nitrogen, nitrite nitrogen, or nitrate nitrogen with low running cost.SOLUTION: A final treatment system of wastewater containing a high concentration of persistent organic matter comprises: a decomposition reaction treatment with an ozone microbubble and/or nanobubble and ozone gas; and also a catalytic reaction treatment reacting in an active carbon catalyst an ozone microbubble and/or nanobubble and a free radical generated by crushing of the ozone microbubble with the persistent organic matter of an acrylic type, etc. and an organic matter-based minute solid substance.SELECTED DRAWING: None
