<p><P>PROBLEM TO BE SOLVED: To provide a wastewater treatment system in which the enlargement of a water treatment apparatus and the increase of running cost are inhibited, and the treatment can be performed stably and efficiently. <P>SOLUTION: The wastewater treatment system includes: an aeration tank 111 which aerates wastewater containing an organic substance, and discharges aeration gas containing the organic substance; a wastewater treatment apparatus 200 which connects with the aeration tank, supplies the wastewater to an adsorption element 211 which adsorbs the organic substance by making the wastewater contact, and desorbs the organic substance absorbed by making heated gas contact, to discharge as a treated water, supplies heated gas to the adsorption element, makes the organic substance desorb from the adsorption element, and discharges as the gas containing the organic substance; a combustion apparatus 310 which connects with the aeration tank and the wastewater treatment apparatus, makes the mixed gas of the discharged aeration gas containing the organic substance and the desorption gas burn to carry out oxidative decomposition, and discharges the decomposition gas, wherein the wastewater treatment apparatus makes the part in which the desorption treatment of the adsorption element is finalized shift to the part which performs the adsorption treatment, and makes the part in which the adsorption treatment of the adsorption element is finalized shift to the part which performs the desorption treatment. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
