臭氧氧化去除水中泰乐菌素的研究

A study on the removal of tylosia by ozone oxidation

探究了臭氧预氧化方法对水环境中普遍存在的泰乐菌素的去除效率,研究了泰乐菌素初始浓度、溶液p H值、臭氧投量和腐殖酸对臭氧氧化去除泰乐菌素效率的影响。结果表明,氧化反应20 min后,泰乐菌素的去除率基本稳定。随泰乐菌素初始浓度的增加,其去除率呈降低趋势;溶液p H值对泰乐菌素的去除率存在一定影响,泰乐菌素的去除率随溶液p H的增加而降低;随臭氧投量的增加,泰乐菌素去除率也随之升高;腐殖酸对泰乐菌素的氧化去除有一定的抑制作用,且浓度越高,抑制作用越强烈。

Focused on ozone oxidation removal of tylosia,a widespread pharmaceuticals in water environ-ments. The effects of initial concentrations of tylosia,solution pH,the dosage of ozone and the humic acid on the removal efficiency were examined. The results show that a high removal could be achieved after 20 min reaction time. When tylosia initial concentration increased,the removal rates were decreased. The solution pH affected the removal efficiencies of tylosia,the removal efficiencies increased as the pH in-creased. As the dosage of ozone increased,the removal efficiencies of tylosia were also increased. The hu-mic acid existed in the solution would inhibit the removal efficiency and the inhibition would be more ob-vious if the concentration of humic acid was higher.
