Description

A kind of agricultural wastes prepare the method for anode of microbial fuel cell electrode
Technical field
The present invention relates to technical field of microbial fuel battery, especially one agricultural wastes prepare micro-life The method of thing fuel cell anode electrodes.
Background technology
In recent years, along with the exhaustion day by day of fossil energy, the burning of the Fossil fuel such as Yi Jimei, oil is to ring The harm that border is caused, finds a kind of resources conservation, environmentally friendly novel energy has become the task of top priority.
It is reported, within 2014, Chinese soybean yield is at about 12,350,000 tons, and import volume is 7140.4 ten thousand tons, Export volume is 2,070,000 tons, and domestic Semen sojae atricolor Apparent con-sumption is 8354.7 ten thousand tons.China is as processing in the world One of major country of Semen sojae atricolor, bean dregs (account for full dried tofu weight as by-product maximum in soybean processing industry 15%~20%), the 16000000 wet bean dregs of t are the most about produced, in current recycling, how as feedstuff Recycle Deng agricultural byproducts, however general bean dregs water content 85%, protein 3.0%, fat 0.5%, Carbohydrate (cellulose, polysaccharide etc.) 8.0%, nutritive value is relatively low, therefore how using bean dregs as agricultural Garbage processes with combustion system, and causing environment to a certain degree affects, and how to carry out it reasonably Recycle and also become a focus merited attention.
Microbiological fuel cell is a kind of to utilize microorganism that the chemical energy in Organic substance is directly translated into electric energy Device.Its basic functional principle is: under anode chamber's anaerobic environment, and Organic substance decomposes under microbial action And discharging electronics and proton, electronics relies on suitable electron transfer mediator to enter between biological components and anode Row effectively transmission, and it is delivered to negative electrode formation electric current by external circuit, and proton is transmitted by PEM To negative electrode, oxidant (generally oxygen) obtains electronics at negative electrode and is reduced and is combined into water with proton, has The feature that generating efficiency is high, low in the pollution of the environment.
In traditional microbiological fuel cell, use active carbon fiber felt as electrode material, be close to Reactor wall, has high specific surface area effective area 2513cm2While), there is good product electricity effect Really (patent name: a kind of three-diemsnional electrode biofilm system being applicable to process low ratio of carbon to ammonium high ammonia-nitrogen wastewater, Number of patent application: 201110373581X).Also have been reported that and use the graphite carbon plate load being wound around NACF Metallic copper palladium is as electrode material (patent name: electrochemistry-biomembrane synergism reactor and having nitrogenous Application in machine waste water, number of patent application: 2013101777107).Electrode performance prepared by these modes is relatively Good, but by analyzing it is seen that, its preparation and raw material relatively costly.But as in the micro-life using preparation While thing fuel cell electrode solves energy problem, agricultural wastes material can be carried out again resource profit With, this technology then has more dissemination.
In recent years, how by agricultural wastes such as useless bean dregs, being allowed to turn waste into wealth has had become as a focus, Cause the close attention of various countries.In order to enable to be formed loose structure in raw material, currently mainly there are two kinds of sides Method.One is template, utilizes template to carry out effective control hole structure, thus prepares structurally ordered, aperture Homogeneous material.(patent name: a kind of based on sacrificing template structure DMFC nanoporous The method of structure membrane electrode, number of patent application: 2013105249177) but this method, relate to template The using and removing of agent, step is complicated, and specific surface area is difficult to promote further.The present invention uses carbonization-activation Method, this is a kind of traditional method preparing porous carbon electrodes, and technical maturity utilizes alkali to carry out low to material with carbon element Cost activates, and prepares high-specific surface area, high capacitance, has the electrode material of good biocompatibility.
