Problems solved by technology

Chemical methods are all at the cost of consuming mineral energy, which inevitably causes environmental pollution in the production process, and all of them need to be carried out under the conditions of high temperature, high pressure or strong acid and strong alkali except the electrolysis method, the reaction conditions are harsh and the cost is high

Embodiment Construction

[0023] 2.1 Experimental principle

[0024] The experimental principle is shown in Figure 1. Anaerobic bacteria can decompose various organic substances into organic acids to obtain the energy and reducing power they need to maintain their own growth, and produce part of hydrogen to eliminate electron accumulation. From the free energy shown in Figure 1, it can be seen that since the reaction can only proceed in the direction of free energy reduction, in the organic acids obtained by decomposition, the removal of formic acid can further decompose H 2 and CO 2 In addition, other organic acids cannot continue to decompose, which is the reason why the hydrogen production efficiency of anaerobic bacteria is very low, and the low hydrogen production efficiency is the main obstacle to the practical application of hydrogen production by anaerobic bacteria. However, photosynthetic bacteria can use light energy to overcome the positive free energy barrier faced by the further decomposi...

Abstract

The present invention discloses hydrogen producing process and apparatus with pig excrement and sewage and photosynthetic bacterium, and aims at providing one solution to the problems of energy source shortage and environmental pollution. The present invention provides the research results on the issue of producing hydrogen with pig excrement and sewage and photosynthetic bacterium Rhodopseudo monas phaeroides AS1.1737. The present invention gives the influence of material concentration, temperature, intensity of illumination, material pH value and other factors on the hydrogen production with the photosynthetic bacterium, and the optimized technological conditions of producing hydrogen with pig excrement and sewage and photosynthetic bacterium Rhodopseudo monas phaeroides AS1.1737, including temperature of 30 deg.c, pH 7.0, intensity of illumination 1600 lux, and sewage concentration of 5687 mg / l.

Description

technical field [0001] The invention relates to a method and device for hydrogen production, in particular a method for producing hydrogen by using photosynthetic bacteria in pig manure sewage and a hydrogen production device thereof. Background technique [0002] With the rapid development of my country's economy, since the end of 1990s, the supply of energy has been in short supply, and the fast-growing economy is facing the dilemma of insufficient "power". In 2004, the total national energy consumption reached 1.97 billion tons of standard coal, an increase of 16% over 2003. In the summer of 2003 and 2004, about 2 / 3 of the provinces in the country implemented blackouts or fixed power supply in turn. The shortage of energy supply has become a bottleneck restricting my country's economic and social development. [0003] At present, the energy we use is mainly coal, oil, natural gas and other mineral resources, which are not renewable. The use of these energy sources also ...
