摘要
利用化学沉淀与固定化微生物组合处理技术对焦化废水进行处理试验。结果表明,经过化学法预处理后,废水中氨氮、苯酚和COD去除率分别为79.82%、26.61%和12.65%;出水再利用厌氧-固定化微生物进一步处理,废水中氨氮、苯酚和COD去除率分别为65.2%、97.22%和96.15%。化学沉淀与固定化微生物组合,氨氮、苯酚和COD总去除率分别达96.6%、99.8%和98.1%。
In this study,it was a treatment test combining chemical precipitation with immobilized live-cell to degradate coking wastewater.Research showed that using the chemical precipitation to remove the ammonia-nitrogen,phenol and COD of waste water,removal rate can reach 79.82%,26.61% and 12.65%,respectively.It was a feasible process in advanced treatment of outflow using the technology of combining anaerobic with immobilized live-cell.The ammonia nitrogen,phenol and COD in waste water removal rates were 65.2%,97.22% and 96.15%,respectively.The result showed we can effectively remove the organic compound combining chemical precipitation with immobilized microorganisms,removal rate of ammonia,phenol and COD can reach 96.6%,99.8% and 98.1%,respectively.
