An exploration into the symbiotic impact of sonic-tenside (SDBS - sodium dodecyl benzene sulfonate) on biomass disintegration potential and to reduce the energy consumption was studied. At optimized condition (specific energy input 9600 kJ/kg TS; SDBS dosage 0.07 g/g SS), higher percentage of biomass lysis and solids reduction (23.9% and 19.8%) was obtained in blended sonic-tenside disintegration (STD), than sonic disintegration (SD) (17.6% and 9.8%). The bioacidogenic potential (BAP) assay in terms of volatile fatty acids (VFA) production (722 mg/L) was found to be higher for STD, in comparison to SD (350 mg/L). The impact of STD on anaerobic digestion was evident from its methane yield (0.239 g/g COD), higher than SD (0.182 g/g COD). A monetary evaluation of the present study provides a net gain of 2 USD/ton for STD, indicating the profitability of the technique.

声波表面活性剂对生物质分解潜力的协同影响：产酸和甲烷潜力研究、动力学和成本分析


研究了声波表面活性剂（SDBS - 十二烷基苯磺酸钠）对生物质分解潜力和降低能耗的共生影响。在优化条件下（比能量输入 9600 kJ/kg TS；SDBS 剂量 0.07 g/g SS），混合声波表面活性剂崩解 (STD) 获得了更高的生物质裂解和固体减少百分比（23.9% 和 19.8%），声波崩解 (SD)（17.6% 和 9.8%）。与 SD (350 mg/L) 相比，STD 的挥发性脂肪酸 (VFA) 产量 (722 mg/L) 的生物产酸潜力 (BAP) 测定更高。 STD 对厌氧消化的影响从其甲烷产量 (0.239 g/g COD) 可见一斑，高于 SD (0.182 g/g COD)。本研究的货币评估显示 STD 的净收益为 2 美元/吨，表明该技术的盈利能力。
