Abstract

The aim of the work was to optimize the ratio of weight of solid (food waste) and liquid (water) phases in order to ensure high efficiency of molecular hydrogen synthesis and degradation of multi-component food waste. Assessment of the efficiency of fermentation process was carried out using colorimetric and potentiometric methods for pH and redox potential measuring, volumetric and chromatographic methods for volume and composition of gas investigation, and mathematical calculations for fermentation parameters determination. The dynamics of hydrogen fermentation of waste in the horizontal reactor using different ratios of solid (food waste) and liquid (water) phases was investigated. The optimization of the ratio of solid and liquid phases was shown to lead to the increase in efficiency of molecular hydrogen synthesis and destruction of waste particles. The ratio of solid and liquid phases 1:3 was determined to be optimal for the effective synthesis of hydrogen as well as for maximum waste decomposition. It provided effective hydrogen fermentation of multi-component food waste and allowed to rationally use material and technical resources. Obtained results are promising for further development of efficient industrial biotechnologies for waste destruction with the simultaneous synthesis of environmentally friendly energy carrier, i.e. molecular hydrogen.

通过优化食物垃圾发酵参数提高产氢效率

这项工作的目的是优化固体（食物垃圾）和液体（水）相的重量比，以确保分子氢合成和降解多组分食物垃圾的高效性。使用比色法和电位法测量pH值和氧化还原电位，体积法和色谱法研究气体的体积和成分，以及数学计算确定发酵参数，对发酵过程的效率进行评估。研究了在水平反应器中，使用不同比例的固相（食物垃圾）和液相（水）对垃圾进行氢气发酵的动力学。固相和液相比例的优化被证明可以提高分子氢合成的效率和破坏废物颗粒。固相和液相的比例1:3被确定为有效合成氢气以及最大限度分解废物的最佳比例。它为多组分食物垃圾提供了有效的氢气发酵，并使材料和技术资源得到合理利用。所获得的结果有望进一步开发用于废物销毁的高效工业生物技术，同时合成环境友好的能源载体，即分子氢。
