摘要
本研究结果表明,对生产维生素C低浓度有机废水。采用酸化——生物接触氧化处理,比单纯的生物接触氧化工艺具有较大的优越性。本文探讨了酸化反应的废水停留时间、温度及浓度对处理效果的影响和酸化手段,对提高废水可生化性的贡献。当酸化柱的平均COD_(Cr)容积负荷为7.16kg/m^3d,好氧柱的平均COD_(Cr)容积负荷为1.78kg/m^3d时,COD_(Cr)平均总去除率达88.64％,BOD_5平均总去除率达92.65％;在进水的COD_(Cr)浓度达1000mg/l时,出水的COD_(Cr)、BOD_5及SS的含量仍可达标。
By experiment the results showed that treatment of low concentrated Vitamin C wastewater with acidi- fication-biological contact oxidation was more effective than the process of biological contact oxidation only. The experiment also approaching the acidification which may be influenced by time interval,tem- perature and concentration of wastewater for treating effect,and the contribution of acidification measures for promoting biodegradability.
