Effect of Supplying Trace Metals of Fe, Co, Ni on Performance of Upflow Anaerobic Filter

摘要

The effect of supplying trace metals of Fe, Co, Ni on the performance of lab-scale upflow anaerobic filter treating simulated coking plant wastewater was studied in this paper. The results showed that the start-up period of the anaerobic filter could be shortened, and the acclimation time for the refractory organic substance could be clearly reduced by supplying these trace metals. The ability to resist shock loading could be enhanced by supplement of trace metals to the anaerobic reactor.
