METHOD AND APPARATUS FOR TREATING DIMETHYL SULFOXIDE-CONTAINING ORGANIC WASTEWATER

摘要

PROBLEM TO BE SOLVED: To recover dimethyl sulfoxide (DMSO) without completely decomposing it, and treat organic matter-containing wastewater.;SOLUTION: In a DMSO-containing wastewater treatment apparatus, after decomposing DMSO in the wastewater to DMS in an anaerobic treatment tank, the DMS is vaporized and recovered, which enables reuse of the DMS as a synthetic raw material of DMSO, and inhibits generation of odorous gas due to decomposition of the DMS. An organic matter other than DMSO in the organic matter-containing wastewater after the anaerobic biological treatment is treated in an aerobic treatment tank.;COPYRIGHT: (C)2010,JPO&INPIT
