青霉素生产废水不同深度处理方法的比较

Comparison of Different Treatment of the Wastewater in the Production of Penicillin

采用Fenton试剂氧化、Cu/Fe催化还原、曝气铁碳微电解3种方法,对青霉素生产废水生化处理后的出水进行了深度处理,考察了不同影响因素对3种处理方法处理效果的影响。结果表明,在H_2O_2添加量为100.0mL/L,H_2O_2/Fe^(2+)(摩尔比)为10,pH值为3.0,反应时间为1.5h时,Fenton试剂氧化法处理效果最好,COD_(Cr)去除率达到83.4%;在铜和铁的总添加量为60.0g/L,Fe/Cu(质量比)为10,pH值为4.0,反应时间为1.0h时,Cu/Fe催化还原法处理效果最好,COD_(Cr)去除率达到62.2%;在铁碳添加量为120.0g/L,pH值为4.0,反应时间为2.0h时,曝气铁碳微电解法处理效果最好,COD_(Cr)去除率达到58.7%。3种处理方法均可有效处理青霉素生产废水生化处理后的出水,其中Fenton试剂氧化法的效果最好。

This paper uses three methods to deal with the wastewater in the production of penicillin. They are Fenton reagent oxidation,Cu / Fe catalytic reduction and Aeration iron-carbon micro-electrolysis. It also investigates the effect of different influence factors on the treatment effect of 3 different treatment methods. The result indicates that when the dosage of H2O2 is 100. 0 m L / L,H2O2/ Fe2＋（ molar ratio） is 10,pH value is 3. 0,reaction time is 1. 5 h,and in that case Fenton reagent oxidation method gets the better effect,and the removal rate of CODCr achieves 83. 4%. When the dosage of copper iron is 60. 0g / L,Fe2/ Cu（ mass ratio） is 10,pH value is 4. 0,reaction time is 1. 0 h,and Cu / Fe catalytic reduction method gets the better effect,and the removal rate of CODCr achieves 62. 2%. When the dosage of iron carbon is 120. 0 g / L,pH value is 4. 0,reaction time is 2. 0 h,Aeration iron-carbon micro-electrolysis method gets the better effect,and the removal rate of CODCr achieves 58. 7%. These three methods can treat the wastewater in the production of penicillin after biochemical treatment effectively,among which Fenton reagent oxidation method can get the best effect.
