WASTEWATER TREATMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a wastewater treatment system which efficiently removes volatile organic components contained in wastewater at a low cost and also efficiently clarify environmental pollution object components originating from volatile organic components contained in wastewater. SOLUTION: The wastewater treatment system for wastewater containing volatile organic components comprises a wastewater storage tank 1 to store wastewater containing volatile organic components and a gas decomposition tank 2 to decompose volatile organic components generated from wastewater in the wastewater storage tank 1. A vapor-liquid separation tank 3 is connected to the gas decomposition tank 2 for vapor-liquid separation of a treated gas 15. A clarification tank 4 is connected to the wastewater storage tank 1 and the vapor-liquid separation tank 3 to clarify the drainage. An ozonolysis tower 6 is connected to the vapor-liquid separation tank 3 to decompose ozone contained in the treated gas 15.
