Embodiment Construction

[0016] Using the two-stage integrated solid fermentation coupled ionic membrane biofuel cell reactor of the present invention, the organic waste water is directly fed into the BFC or the raw material of the organic biological waste is sent into the fermentation reaction chamber after being pulverized. Under the action, the organic matter is degraded and converted into sugars, organic acids and other substances. After percolation, the filtrate enters the biofuel cell chamber. For hydrogen production or power generation. The parameters of the reaction system, such as pH 4-6, temperature controlled at 30-60°C, growth factors operated according to the following ratios, residues removed for use as fertilizers, and hydrogen or electricity generated are used in a suitable manner. The proportion of growth factors: COD 6~25g / L, urea 0.5~1.0g / L, phosphate 0.1~0.2g / L, the proportion of other major growth factors is MgSO 4 ·7H 2 O: FeCl 3 : NiSO 4 : CaCl 2 :Na 2 BO 7 ·H 2 O:(NH 4...

Abstract

The invention provides a method for generating hydrogen and converting electricity generation with a biological fuel cell reactor, relating to the filed of environment and biological energy source. The invention uses the biological fuel cell (BFC) reactor to treat solid or liquid organic wastes and convert organic matter into hydrogen gas fuel with high added value or electric energy. By adjusting the process of generating hydrogen/ converting electricity generation electrode of the BFC reactor, the invention can improve the conversion efficiency and the use efficiency of the energy. The method couples the electrode of the anaerobic BFC reactor with microorganism into a whole body, ferments the organic matter in way of anaerobism as required, and links a bioelectricity chemical unit to react so as to generate hydrogen or convert electricity generation. By directly converting the electrode process of the BFC reactor of the organic matter biological fermentation, the method can develop the clean biological energy source for generating hydrogen or generating electricity, reasonably switches the hydrogen generation into the electricity generation, and improves reacting efficiency.

Description

technical field [0001] The invention relates to the field of environment and bio-energy, in particular to a method for treating solid or liquid organic waste by using a biofuel cell (BFC) reactor, and converting organic matter into high value-added hydrogen fuel or into electric energy. Background technique [0002] The harmless recycling of organic pollutants has always been a problem faced by countries all over the world. Foot-and-mouth disease, mad cow disease, and bird flu have made people change the traditional way of treating traditional catering organic waste as feed. Dioxins and other harmful gases produced during waste incineration have also led many countries to formulate strict regulations on the use of this technology. Therefore, people increasingly feel the urgency of developing green organic matter treatment and resource recovery system. In order to solve the problem of harmless and resourceful organic wastewater and waste, bio-composting technology is widely ...
