Abstract

The invention discloses a microbial electro-catalysis-based small-sized organic waste treatment device and treatment method for villages and towns; an anaerobic biogas digester is coupled with a microbial electro-catalysis system, and the small-sized movable organic waste treatment device suitable for villages and towns is constructed; and the electro-catalysis performance of electroactive microorganisms is utilized, the bottleneck problem that electron donors are insufficient in the anaerobic fermentation process is solved, deep treatment of organic waste is achieved on the anode, meanwhile, carbon dioxide in biogas is further converted into methane on a cathode, and biogas upgrading and purification are achieved. According to the method, the potential value of rural household biogas engineering can be fully excavated, the problem that the biogas engineering is idle is fundamentally solved, the pressure of rural energy requirements is relieved, the utilization way can be widened, the generated liquid organic fertilizer is used for farmland soil improvement, cooperative treatment of agricultural production and domestic waste can be achieved, and the purposes of heating and cleaning home furnishing, economical and efficient courtyard and harmless agricultural production are achieved.

Description

technical field

[0001] The invention belongs to the field of green energy conversion of organic waste, and in particular relates to a small-scale organic waste treatment device in villages and towns based on microbial electrocatalysis.

[0002] The invention also relates to a method for treating small-scale organic waste in villages and towns by using the above-mentioned device. Background technique

[0003] The scale of biogas projects in villages and towns in my country is increasing year by year. At present, more than 40 million rural household biogas projects have been built nationwide, benefiting more than 200 million people. In villages and towns where fermentation raw materials are abundant and energy consumption is scattered, the popularization and application of household biogas digesters has changed the traditional production and lifestyle of farmers. By combining household biogas digesters with livestock and poultry pens and toilets, the functions of biogas diges...
