Experiments in this reactor[electric current 60 mA, hydraulic retention time(HRTs) 6.0 h] showed that the removal of COD_ Cr, ammonia nitrogen and total nitrogen in the biofilm-electrode reactor were 2.5%, 1.2%, 14.9%, respectively, higher than those in a traditional biofilm reactor.展开更多
文摘The denitrification of municipal sludge was improved by combining biofilm process with the electro-chemical effect in a single novel reactor. Experiments in this reactor[electric current 60 mA, hydraulic retention time(HRTs) 6.0 h] showed that the removal of COD_ Cr, ammonia nitrogen and total nitrogen in the biofilm-electrode reactor were 2.5%, 1.2%, 14.9%, respectively, higher than those in a traditional biofilm reactor.
