specific Embodiment approach 1

[0012] Specific implementation mode one: combine figure 1 and figure 2 Illustrate that this embodiment utilizes the method for protein to produce hydrogen in the microbial electrolysis cell to realize according to the following steps:

[0013] 1. Start the reactor in electricity production mode: a resistor 1 is set in the closed circuit using the electrolytic cell as the power supply, and the domestic sewage and the nutrient solution A are uniformly mixed according to the volume ratio of 1:1 to obtain the mixed solution C, and then the mixed solution The liquid C is passed into the electrolytic cell, and the new mixed liquid C is replaced under the condition that the voltage across the resistance 1 of the closed loop is lower than 25mV, and the mixed liquid C is continuously replaced until the voltage across the resistance 1 is greater than 500mV;

[0014] 2. Dissolve the protein in the nutrient solution B to obtain the mixed solution D, then replace the mixed solution C in ...

specific Embodiment approach 2

[0020] Embodiment 2: This embodiment differs from Embodiment 1 in that the domestic sewage in step 1 is obtained from the primary sedimentation tank of the urban sewage treatment plant. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0021] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the cathode Pt load in step one is 0.5 mg / cm 2 . Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

A method for generating hydrogen in microorganism electrolysis cell with protein relates to a hydrogen generation method. The invention settles a problem that the prior fermentation method can not use protein for generating hydrogen. The method of the invention comprises the following steps: 1. actuating a reactor when the electrolysis cell is in a power generation mode; 2. using the protein as zymolyte for domesticating the functional microorganism of anode; and 3. using the protein as zymolyte for generating hydrogen when the electrolysis cell is in a hydrogen generation mode. The invention uses a microorganism electrolysis cell technique for directly preparing hydrogen from protein. The method of the invention has the advantages of high utilization factor of protein and high removal rate to COD, and can be used for treating the organic waster water and organic solid waste which are rich in protein and can be simultaneously used for recycling the energy product of hydrogen gas with higher economic value. The method has a characteristic of combing pollution control and energy production.

Description

technical field [0001] The invention relates to a method for producing hydrogen. Background technique [0002] Hydrogen energy is a non-polluting, renewable and high-energy-density energy source, and is recognized as the most attractive alternative energy source. There are three main production methods at present: 1. Using fossil fuels as raw materials to prepare hydrogen through chemical means such as catalytic cracking and gasification; 2. Generating hydrogen through electrolysis of water; 3. Biologically producing hydrogen by fermentation; The third method has the advantages of high energy consumption and secondary pollution. Because renewable biomass energy can be used as raw material, it has the advantages of cleanliness, low energy consumption, recyclability and pollution control at the same time. approach, but this method mainly uses carbohydrates and organic acids as raw materials, and the existing fermentation methods cannot directly use protein as raw materials. ...
