A reaction system suitable for resource utilization of organic solid waste

Abstract

A reaction system suitable for resource utilization of organic solid waste, which belongs to the field of anaerobic biological treatment of solid waste, can solve the problems of easy "acidification" in the reaction process of the prior art, low fermentation efficiency and gas production efficiency, including high temperature Hydrolysis fermentation reaction device, medium temperature acidification fermentation reaction device and methane fermentation reaction device, three independent reaction devices respectively form hydrolysis dominant bacteria group, acid production dominant bacteria group and methanogenic bacteria group and provide the best conditions for their growth , which can effectively avoid the phenomenon of "acidification" and cause the reaction device to fail to operate normally. Each device injects the biogas slurry into the next reaction device through the water distribution device through the jet pump on the connecting pipe, which can not only fully stir the reaction device, increase the contact area between the reaction substrate and the sludge, and reduce the failure of mechanical agitation, Problems such as high energy consumption can also achieve the purpose of biogas slurry circulation, so that organic solid waste can be thoroughly fermented again, and the generation of biogas residue can be reduced.

Description

technical field [0001] The invention relates to an anaerobic fermentation device for organic solid waste, belonging to the technical field of anaerobic biological treatment of solid waste. Background technique [0002] With the rapid development of social economy, the amount of solid waste is increasing day by day. How to reduce its quantity and recover resources and energy therefrom has become an urgent problem to be solved. [0003] Solid wastes such as agricultural waste, meal waste, distiller's grains, excess sludge and organic domestic waste contain a large amount of organic matter, which can be converted into energy, stable products and other useful substances by means of biological action, and at the same time realize the efficiency of solid waste treatment and disposal. Reduction, recycling and harmless, to achieve comprehensive recycling of resources. [0004] Compared with aerobic biological treatment technology, anaerobic biological treatment technology is more ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a reaction system suitable for resource utilization of organic solid waste, which solves the problems of easy "acidification" in the reaction process of the prior art, low fermentation efficiency and gas production efficiency, and can overcome the problems in the prior art at the same time. Mechanical agitation is prone to failure, energy consumption and difficulty in handling biogas residues, which is conducive to the stable operation of high load and high efficiency in the reaction system
