AI Technical Summary
Technical Problem
Existing advanced oxidation technologies suffer from catalyst loss and lack of specificity, resulting in high persulfate usage and poor removal of antibiotic resistance genes.
Method used
Lanthanum ferrite supported on silica is used as the adsorbent. The adsorption effect is enhanced by the binding of lanthanum ferrite particles with antibiotic resistance genes. Iron is used to activate the oxidant for oxidation. Combined with magnetic response characteristics, it is easy to recycle and regenerate.
Benefits of technology
It improves the adsorption efficiency of antibiotic resistance genes and the specificity of oxidation treatment, reduces catalyst loss and oxidant usage, and lowers wastewater treatment costs.

Abstract
本发明公开了一种废水处理方法，涉及环境保护技术领域，所述废水处理方法包括：将吸附剂加入废水中，得到处理后的废水；其中，所述吸附剂包括二氧化硅负载的镧铁氧体，用以吸附所述废水中的抗生素抗性基因。二氧化硅负载的镧铁氧体粒子与废水中吸附底物结合的接触面积较大，增强了吸附剂对废水中的抗生素抗性基因的吸附效果；吸附剂在完成吸附后，抗生素抗性基因直接与铁元素接触，便于铁元素对氧化剂进行激活和激活后的氧化剂对抗生素抗性基因进行氧化，提高了后续氧化处理的专一性；吸附剂中镧铁氧体具有磁响应特性且二氧化硅载体也增强了镧铁氧体的沉降性能，因此吸附剂更容易从废水中分离回收并重复利用，降低了废水处理的成本。
