摘要: Highlights: • Effect of low frequency ultrasound pretreatment on leachate was investigated. Three different energy inputs (200, 400 and 600 W/l) applied. Low-frequency treatment increased soluble COD in landfill leachate. Application to biogas production about 40%. total methane rate 20%. - Abstract: The aim this study is increase yield from anaerobic batch reactors by using as a step. In the first part study, optimum conditions for solubilization organic matter samples were investigated various sonication durations at an 20 kHz. level during ultrasonic experiments determined calculating ratio chemical oxygen demand (sCOD) (tCOD). sCOD/tCOD 47% raw 63% after 45 min W/l. Non-parametric Friedman’s test indicated that has significant effect sCOD parameter (p < 0.05). second operated bothmore » ultrasonically pretreated untreated order assess rate. reactor feed with leachate, 40% more obtained compared control reactor. For statistical analysis, Mann–Whitney U performed compare rates it been found significantly enhanced 0.05) reactors. overall results showed can be potentially used wastewater management especially integration processes.« less
