In this study an integrated pre-treatment stage of waste banana peel biosorbent and sonication was investigated to qualify a mixture of brewery (BE) and restaurant (RE) effluents for photo fermentative hydrogen production without using standard medium. Different blending ratios of brewery and restaurant effluents and different sonication amplitudes (30, 60, and 90%) and sonication time (15, 25, 35, and 45 min) were investigated. The experimental results demonstrated that applying the proposed integrated pre-treatment (2 g L⁻¹ waste banana peel biosorbent and 35 min sonication at 60% amplitude) for a mixture of 70% RE and 30% BE enhanced the cumulative biohydrogen production to 110 ± 4 mL (144% enhanced), while applying single pre-treatment stage (2 g L^-1 banana peels waste biosorbent) enhanced the cumulative biohydrogen production to 83 mL (84% enhanced). Furthermore, more than 46% of soluble chemical oxygen demand (SCOD) removal was achieved during photo-fermentative hydrogen production process. The results also demonstrated that the proposed integrated pre-treatment stage is a promising technique not only for enhancing the biohydrogen production but also contributes in the treatment of the wastewater by reducing the COD.

在这项研究中，对废香蕉皮生物吸附剂和超声处理的集成预处理阶段进行了研究，以使啤酒厂（BE）和饭店（RE）废水的混合物不需使用标准培养基即可进行光发酵制氢。研究了啤酒厂和餐厅废水的不同混合比例以及超声处理幅度（30％，60％和90％）和超声处理时间（15、25、35和45分钟）的不同。实验结果表明，对70％RE和30％BE的混合物应用拟议的综合预处理（2 g L ^-1废香蕉皮生物吸附剂和35分钟超声处理，振幅为60％）可将累积生物氢产量提高至110± 4 mL（增强144％），同时应用单个预处理阶段（2 g L ^-1香蕉皮废物生物吸附剂）将累积的生物氢产量提高至83 mL（提高了84％）。此外，在光发酵制氢过程中，去除了超过46％的可溶性化学需氧量（SCOD）。结果还表明，提出的集成预处理阶段不仅是提高生物氢产量的有前途的技术，而且通过减少COD有助于废水的处理。
