摘要
Abstract
A pilot-scale study on the denitrification treatment of cold rolling waste water utilizing IBR process was carried out in a steel plant,and the treatment effect under design parameters was investigated.The experiments showed that total nitrogen removal loading was more than 0.08 kg TN/kg MLSS · d and removal rate was as high as 96.66％,under the design parameters pH value≈8.0,MLSS ≈6 000 mg/L,T≈30 ℃,R≈10,DO≈4.0 mg/L (anoxic zone),DO＜0.5 mg/L (oxic zone).Effluent indexes such as TN,COD concentration could meet the relevant requirements of subsequent biofilm process.Compared with other process technologies,IBR process could maintain high sludge concentration with no internal moving parts,operation cost was low and less field area was used.Also,technical improvements on the process were convenient and cheap because of its simplicity.关键词
