Embodiment 1

[0029] Brewery wastewater with a COD concentration of 12,500 mg / L flows continuously at a rate of 1,680 liters / day into a hydrogen production reactor with an effective volume of 700 liters for hydrogen production by fermentation. The fermentation process is carried out under anaerobic conditions, and the fermentation reaction temperature is 34°C, so that 4.0m per day can be produced 3 of hydrogen.

Embodiment 2

[0031] The beer wastewater with a COD concentration of 17000mg / L is continuously flowed into a hydrogen production reactor with an effective volume of 700 liters at a rate of 1680 liters per day for hydrogen production by fermentation. The fermentation process is carried out under anaerobic conditions, and the fermentation reaction temperature is 32 ℃, so that 5.1m 3 of hydrogen.

Abstract

The present invention relates to hydrogen preparing method, and is especially one kind of hydrogen preparing method with industrial organic waste water and microbe. Inside one common hydrogen generator, industrial organic waste water as material and biological hydrogen preparing fermenting liquid are used to prepare hydrogen via fermentation under anaerobic condition. The method is a normal temperature and normal pressure hydrogen preparing process, and can prepare hydrogen as clean energy source in low cost while treating industrial waste water. The present invention has wide material source, simple metabolite and industrial practicability.

Description

technical field [0001] The invention relates to a method for preparing hydrogen, in particular to a method for preparing hydrogen by utilizing industrial organic waste water. Background technique [0002] At present, fossil fuel reserves as the main body are limited, and CO2 is produced when burned 2 And nitrogen, sulfur and other oxides, once these substances are discharged into the atmosphere, they are all air pollutants that affect the living environment of human beings. In order to promote the coordinated development of economy and environment and implement a sustainable development strategy, it is necessary to seek a new way of rational utilization of energy. The development and transfer to other renewable new energy sources has reached a worldwide consensus, which makes hydrogen an ideal development object unanimously recognized by researchers from all over the world. [0003] Hydrogen only produces water when it is burned, and it is a clean energy that can achieve z...
