Treatment of leachate generated from municipal solid waste using different configurations of ultrasonic (US) reactors in combination with advanced oxidation processes based on ozone, hydrogen peroxide (H₂O₂) and Fenton has been investigated in the present work. US configurations investigated were US horn, US flow cell and US bath with variation in mode of irradiation, operating volume and power consumption. The different approaches investigated were only US, US combined with ozone at fixed flow rate as 500 mg/h (US/O₃), US/H₂O₂ and US/Fenton at different loadings of oxidants. For the case of US horn, the obtained extents of COD removal were 6, 24.5, 42 and 73% for different approaches of only US, US+ ozone, US+ H₂O₂ (5 g/L as the best loading) and US+ Fenton (Fe²⁺/H₂O₂ molar ratio as 1:10) respectively. US flow cell gave extent of COD removal as 44, 50, 72 and 92% when operated in different approaches as only US, US+ Ozone, US+ H₂O₂ (5 g/L as the loading) and US+ Fenton (Fe²⁺/H₂O₂ molar ratio as 1:10) respectively. US bath operated under optimized parameters established from studies in US flow cell as H₂O₂ loading of 5 g/L and Fe²⁺/H₂O₂ ratio of 1:10 resulted in COD removal of 90%. Synergetic coefficient and biodegradability index (BI) were also calculated and the most effective process established was US flow cell+ Fenton yielding maximum COD removal of 92% with increased BI from 0.36 to 0.55 and synergetic coefficient of 3.17. Energy efficiency and cost calculations for the US flow cell and US bath with Fenton established that treatment cost was 28.7 and 25 US$/m³ respectively. Overall the combination of US flow cell with Fenton has been established as the most viable approach for leachate treatment.

在本工作中，已经研究了使用不同构造的超声（US）反应器结合基于臭氧，过氧化氢（H ₂ O ₂）和芬顿的先进氧化工艺处理城市固体废物产生的渗滤液。被调查的美国配置是美国号角，美国流通池和美国浴，它们的照射方式，工作量和功耗都有变化。所研究的不同方法仅是US，US与固定流速为500 mg / h（US / O ₃），US / H ₂ O _2的臭氧组合和US / Fenton在不同的氧化剂负载量下。就美国号角而言，仅使用US，US +臭氧，US + H ₂ O ₂（5 g / L为最佳装载量）和US + Fenton的不同方法，所获得的COD去除率分别为6、24.5、42和73％。（Fe ²⁺ / H ₂ O ₂摩尔比为1∶10）。当以不同方式操作时，US流通池给出的COD去除率分别为44％，50％，72％和92％，因为仅US，US +臭氧，US + H ₂ O ₂（以5 g / L作为装载量）和US + Fenton（Fe ²⁺ / H ₂ O ₂摩尔比分别为1:10）。US槽在优化的参数下运行，该参数是根据在美国流通池中进行的研究确定的H5 g / L的₂ O ₂负载量和1：₂的Fe ²⁺ / H ₂ O ₂比率导致90％的COD去除。还计算了协同系数和生物降解指数（BI），确定的最有效方法是US流通池+ Fenton产生的最大COD去除率为92％，BI从0.36增加到0.55，协同系数为3.17。美国流动池和美国芬顿浴场的能效和成本计算确定，处理成本分别为28.7美元/ m ³和25美元/ m ³。总的来说，US流通池与Fenton的结合已被确定为渗滤液处理的最可行方法。
