一种超声协同氧化锌/石墨烯光催化联合预处理老龄垃圾渗滤液的方法
摘要：
本发明属于污水处理领域，涉及老龄垃圾渗滤液的预处理技术，具体涉及的是一种超声协同氧化锌/石墨烯光催化联合预处理老龄垃圾渗滤液的方法，该方法为取待处理渗滤液，调节PH为10倒入反应器中，加入氧化锌/石墨烯复合材料，搅拌使之混合均匀，超声处理同时进行曝气，反应10min～30min，关闭超声设备和曝气设备；打开高压汞灯照射1.5h～3.0h；本发明与单独采用超声波氧化处理的方法相比，采用超声协同氧化锌/石墨烯光催化联合预处理的方法COD的去除率提高了35％至40％，NH3‑N的去除率提高了45％至50％；与单独采用氧化锌/石墨烯光催化氧化处理的方法相比，采用超声协同氧化锌/石墨烯光催化联合预处理的方法，COD的去除率提高了35％至37％，NH3‑N的去除率提高了40％至42％。
摘要（英）：

The invention belongs to the field of sewage treatment and relates to a mature landfill leachate pretreatment technology, in particular to an ultrasonic and synergic zinc oxide/graphene photocatalysis combined mature landfill leachate pretreatment method. The method comprises the steps that to-be-treated leachate is taken, PH is regulated to 10, the leachate is poured into a reactor, a zinc oxide/graphene composite material is added and is stirred and evenly mixed, aeration is performed while ultrasonic treatment, reaction is performed for 10-30 minutes, and an ultrasonic device and an aeration device are closed. A high-pressure mercury lamp is started to perform irradiation for 1.5-3.0 hours. Compared with a method singly adopting ultrasonic wave oxidation treatment, the COD removal rate of the ultrasonic and synergic zinc oxide/graphene photocatalysis combined pretreatment method is improved by 35%-40%, and the NH3-N removal rate is improved by 45%-50%. Compared with a method singly adopting zinc oxide/graphene photo-catalytic oxidation pretreatment, the COD removal rate of the ultrasonic and synergic zinc oxide/graphene photocatalysis combined pretreatment method is improved by 35%-37%, and the NH3-N removal rate is improved by 40%-42%.
