| titleOfInvention | Removal of dioxins, pcb's and other halogenated organic compounds from wastewater |
| abstract | ABSTRACT Combinations of physicochemical and biological treat-ment processes are capable of removing dioxins, polychlorobi-phenyls (PCB's) and other halogenated organic compounds from wastewaters; the dioxins and PCB's are removed by at least 90 percent in the pretreatment steps of neutralization, oxidation, and sedimentation; the residual amounts are removed in a powdered activated carbon enhanced sequencing batch reactor (PAC-SBR) operating at high mixed liquid suspended solids concentration ( > 5000)mg/L); power activated carbon (PAC) is supplemented to the bioreactor to ensure complete removal of the dioxins (<0.8 ppt) and PCB's (<2 ppb); the PAC-SBR enhanced biological treatment process is capable of meeting stringent effluent limits not only on dioxins and PCB's hut also on other toxic halogenated organic compounds; the treatment cost of this process is sub-stantially less than either the conventional granular acti-vated carbon adsorption technology or two stage treatment of biodegradation and carbon absorption. |
