METHOD FOR TREATING WASTE WATER CONTAINING SULFUR-CONTAINING ORGANIC COMPOUND

摘要

PROBLEM TO BE SOLVED: To prevent the generation of a bad smell and reduce the treatment cost when the water which is to be treated and contains an organic compound containing sulfur such as dimethyl sulfoxide (DMSO) is treated by physicochemical treatment and biological treatment.

SOLUTION: The subject waste water treating method is carried out by using the physicochemical treatment process 4 and the biological treatment process 8 for biologically treating the water treated at the process 4. When the water 2 to be treated is treated, a part or the whole of the water 2 is sent directly to the process 8 through a bypass line 10 without sending it to the process 4.
