2024/3/11/ · This study demonstrated the advantages and feasibility of ionizing irradiation pretreatment for the anaerobic fermentation of kitchen waste with the aim of

2012/10/1/ · Fermentation yielded 670 NL biogas/kg volatile solids (VS) with the CSTR and 550 NL biogas/kg VS with the FBR. The productivities were 3.9 NL biogas/ (L*d) with the CSTR and 3.4 NL biogas/ (L*d) with the FBR. The average methane concentration was approximately 60% for both reactor systems.

This design is a set of large-scale fresh kitchen waste energy-saving and emission reduction device. The device is mainly composed of three systems: garbage bin transportation and dumping unloading system, fresh kitchen waste crushing and pushing system, proportioning and fermentation monitoring electronic control system.It can

Here, we review the bottlenecks of anaerobic digestion treatment of kitchen waste, with focus on components inhibition, and energy recovery from biogas slurry and residue. We

2022/11/10/ · A two-phase kitchen waste chain elongation fermentation system is presented. • Organic loading and pH have significant effects on acidification phase. • The optimal acetate to butyrate ratio for chain elongation was 1.00. • Relative abundance of Clostridium kluyveri increased by 109 % or 277 %.

2023/7/28/ · Anaerobic fermentation (AF) can effectively dispose of kitchen waste (KW) without the shortcomings of traditional such as incineration and sanitary landfill. However, KW has a high organic content, which easily leads to acidification and ammonia inhibition during digestion. To mitigate this issue, anaerobic co-digestion

2021/1/1/ · Co-digestion in anaerobic fermentation has been widely used to improve biogas production. The biogas production from co-digestion of glucose and glycerol was studied in laboratory-scale batch

2012/12/13/ · Kitchen waste is defined as left-over organic matter from restaurants, hotels and households [3]. Tons of kitchen wastes are produced daily in highly populated areas. Kitchen wastes entering the mixed-municipal waste system are difficult to process by standard means, such as incineration, due to the high moisture content [2].

2022/2/21/ · To develop a proper system for waste management, one has to understand the availability of resources, the waste generated, and the environmental conditions of that very area. To enhance the pH reaction of the enzyme, the dosage is examined. In addition to this, in the further examination, fermentation of WG by using the

2010/6/1/ · The results indicated that the incubation of yeast presented an obviously inhibition on the lactic acid-producing bacteria in kitchen waste anaerobic fermentation system. Owing to the available

2013/2/1/ · After Large pericarps were removed, the kitchen waste was crushed by an electrical blender and then. SCFA production from WAS and kitchen waste in anaerobic fermentation system: model fitting, data analysis and process optimization. The experimental and predicted responses of SCFA production based on CCD tests are

Anaerobic fermentation of kitchen waste can produce methane while processing kitchen waste, Effects of the added carbon materials on the anaerobic fermentation of food waste [1] 2.1. System ...

About 1.6 billion tons of food are wasted worldwide annually, calling for advanced to recycle food waste into energy and materials. Anaerobic digestion of kitchen waste allows the efficient recovery of energy, and induces low-carbon emissions. Nonetheless, digestion stability and biogas production are variables, due to dietary habits and seasonal

The direct control of anaerobic fermentation tank adopts STM32 single chip microcomputer and DSP as the lower machine, laptop computer as the upper machine, equipped with expert system.Nano-Fe3O4 iron powder was innovatively used to complete the work of temperature regulation module and agitation module, and the fermentation efficiency of
