Use of Fixed-Film, Anaerobic Bioreactors for Energy-Conserving Treatment of Meatpacking Wastewaters

摘要

A new wastewater treatment process based on the anaerobic approach has been developed at Oak Ridge National Laboratory. This treatment process is based on a packed-bed reactor to which anaerobic microorganisms have been added. An attempt was made to determine experimentally if waste waters from a meatpacking plant could be treated in a laboratory-scale ANFLOW (anaerobic upflow) bioreactor. This included evaluating a packing material for use in the bioreactor, demonstrating the development of fixed films in the bioreactors, and determining the times required for system start-up. The performance of the bioreactor in removing carbon from the waste waters and in producing methane as a by-product is evaluated. (ERA citation 09:010133)
