碱渣废水水量少、污染负荷高,是炼油行业高浓度、难降解有机废水.研究了铁铜微电解工艺对碱渣废水处理效果,结果表明:当初始pH为5,曝气时间为8 h,填料填充率为35%时,微电解工艺对COD_(Cr)和色度的去除效率分别达到60%和91%,出水BOD/COD提高至0.44,从而满足后续生化处理的水质需求.GC-MS图谱表明:废水中有机物在微电解工艺中得到有效削减.微电解工艺处理碱渣可行性高,出水水质得到有效改善,降低了炼油厂排放的污染物负荷.

Refinery alkaline wastewater was characterized as toxic,anti-biodegradable with high-organic load although its flux was fairly low.Treatment of refinery alkaline wastewater by iron-copper inner-electrolysis was investigated.The results showed that removing rates of COD_(Cr) and color were 60% and 91% respectively in aeration of 8 hours with 35% filling of carrier at pH=5.The biodegradability of effluent was increased from 0.05 to 0.44,which could match the sequent requirements for biochemical treatment.GC-MS spectrum showed that organic matters in effluent were greatly reduced.Treatment of refinery alkaline wastewater with iron-copper inner-electrolysis was a potential technology,which improved the quality of effluent and reduced the organic load of discharge for refinery plant.
