摘要

通过在废水中加入NaCl电解质,考察了电解阳极间接氧化法制药废水的处理效果。实验分析了废水中电解质NaCl对制药废水电解过程中COD_Cr、色度去除的影响,并对不同用量NaCl电解效果进行了对比。另外还用电解质Na₂ SO₄ 、NaNO₃ 作了对比实验来说明NaCl产生的电解阳极间接氧化的存在。最后对甲红霉素废水进行中试实验,结果表明,NaCl电解产生的NaClO具有极强的氧化性,促进了COD_Cr的去除,同时还发现,废水中氨氮的存在不利于废水COD_Cr的去除。

Abstract

Experiments are conducted to study the role of anode indirect oxidation of electrolysis in treatment efficiency.In this investigation, the ef fects of NaCl on removing chromaticity and COD_Crof pharmaceut ical wastewater have been studied.The study is also done to advance the know ledge of the influence of NaCl dosage on the electrolysis efficiency.Compared w ith the effects of Na₂SO₄, NaNO₃ on the elect rolysis ef ficiency,the results show that the COD_Cr removal can be mainly attributed to the indirect oxidation ef fect of NaCl in elect rolysis process.In practical pharmaceutical wastew ater t reatment, the results indicate that the use of NaCl can achieve higher COD_Cr removal.In addition, the existence of ammonium will result in a decreased COD_Cr removal efficiency.

Key words： electrolysis; pharmaceutical wastewater; indirect oxidation; NaCl; ammonium
