摘要: Experiments were conducted in virgin granular activated carbon (GAC) columns supplied with treated surface water and the synthetic organic chemicals (SOCs) phenol 2,4-dichlorophenol (DCP). The was subjected to one of three chemical treatments: chlorination, no oxidant addition, or ozonation. GAC seeded only microorganisms that passed through conventional treatment. main objective a determination time required initiate significant biodegradation trace concentrations SOCs. impact naturally occurring compounds type pretreatment on also interest, as sorbed Significant DCP liquid phase commenced after month operation contact times <1 min. Sorbed biodegraded large extent, whereas negligible. Total removal across dependent pretreatment. Ozonation caused an increase microbial activity comparison but this did not provide improved DCP.
