WASTEWATER TREATMENT APPARATUS

摘要

A wastewater treatment apparatus (10) for treating a wastewater containing a substance being difficult to decompose, which comprises a wastewater treatment tank (12) for treating a waste water (11), an oxidizing agent addition device (14) for adding an oxidizing agent (13) to said wastewater treatment tank (12), and an alkali agent addition device (16) for adding an alkali agent (15) to the wastewater treatment tank (12). The above substance being difficult to decompose in a wastewater can be completely decomposed by setting the pH in the wastewater treatment tank (12) at the alkali side and subjecting the tank to an oxidation treatment with an oxidizing agent.
