Embodiment Construction

[0027] Implementation column 1:

[0028] The schematic diagram of the experimental device is as follows: figure 1 As shown, the reaction temperature is 37°C, the gas volume is collected by a gas bag and then measured by the drainage method, and the hydrogen content is measured by a gas chromatograph. Before and after the anaerobic dry fermentation reaction, the concentration of carbohydrates, proteins, SCOD and liquid phase end fermentation products in the reaction system were measured; the determination methods were all analyzed by national standard methods (Table 1).

[0030]

[0031] In the experiment, 300g of anaerobic granular sludge, 100 pieces of dried kitchen waste and 0g, 0.3g, 0.6g, and 0.9g of chloroform were added to a 1L Erlenmeyer flask (Table 2).

Abstract

The invention discloses a method for strengthening anaerobic dry fermentation hydrogen production of kitchen waste, and belongs to the technical fields of treatment and utilization of solid waste and environmental protection purification treatment. The hydrogen production effect of the kitchen waste is strengthened by adding chloroform into an anaerobic dry fermentation system, the kitchen waste is effectively disposed, harmless and resourceful treatment for the kitchen waste is realized, the production efficiency of hydrogen is further improved, and the recycling of hydrogen energy is realized. The hydrogen production quantity can be obviously improved by adopting only 0.05% of chloroform, the maximum accumulated hydrogen production quantity is 29.66 mL/g TS, and the degradation rate of carbohydraten reaches 43.07%.

Description

technical field [0001] The invention relates to a method for intensifying hydrogen production by anaerobic dry fermentation of kitchen waste, and belongs to the technical fields of solid organic waste treatment and utilization, and environmental protection purification treatment. Background technique [0002] Food waste refers to food residues and wastes generated in catering activities such as households, catering services, or unit meals. Food waste contains a large amount of organic matter such as starch, plant cellulose, animal oil, protein, etc., which is prone to corruption and odor. If it is not strictly managed and disposed of, it will easily cause harm to the environment. [0003] At present, the treatment methods of food waste include aerobic composting, landfill, incineration, anaerobic fermentation and feed, among which anaerobic fermentation is considered to be one of the ideal ways to deal with food waste because it can realize energy recovery. Anaerobic fermen...
