PROBLEM TO BE SOLVED: To provide a wastewater treatment system capable of maintaining treatment performance, reducing energy consumption, and safely and stably treating wastewater, even when the wastewater load varies beyond a designed value.SOLUTION: The wastewater treatment system includes: an aerator 111 which vaporizes and removes organic substances from wastewater; a continuous adsorption-desorption-type wastewater treatment device 200 connected to the aerator, which adsorbs organic substances through contact with wastewater containing organic substances and desorbs organic substances through contact with heated gas; and a combustion device 300 which burns the mixed gas of aeration gas containing organic substances discharged from the aerator and the continuous adsorption-desorption-type wastewater treatment device and desorption gas for oxidative decomposition, and discharges the decomposition gas as outlet gas. The wastewater treatment system is provided with means 322 for detecting the inlet gas temperature and the outlet gas temperature, or the difference in temperature between the inlet gas and the outlet gas, and controlling the gas volume supplied to the continuous adsorption-desorption-type wastewater treatment device and the repetition cycle of the adsorption-desorption corresponding thereto. |
