Abstract: A high efficiency biometric device for producing hydrogen and methane mainly uses a two-stage anaerobic fermentation device to transform an organic wastewater mixed solution into hydrogen, methane, carbon dioxide and a removal liquid, and then uses a solid liquid separation tank to filter and separate the removal liquid to reduce the sludge and obtain the treated water with a good property. The characteristic lies in that the two-stage anaerobic fermentation device comprises a first anaerobic fermentation tank, a neutralization tank, a feeding tank and a second anaerobic fermentation tank composed of anaerobic fermentation tanks disposed in parallel. The biometric device can increase the removal rate and the methane recovery, and also has a generator for combusting the recycled gas to advantageously have the low energy consumption. Thus, the organic waste contamination is decreased, and the green energy production pathway is also increased.

Abstract: A hybrid renewable energy supply system is mainly applied to a stationary or mobile actual mass-production power generating operation to transform a lot of organic waste into electric energy using a gaseous biomass power plant, and may be combined with renewable energy such as solar energy, wind energy, micro-hydro energy and the like, thereby providing a self-operating system without using mains. The gaseous biomass power plant can use an organic material source, such as food wastewater, livestock farming wastewater, agriculture waste or the like, to generate a biomass gas, thereby possessing dual effects of waste recovery and clean energy production. The hybrid renewable energy supply system comprises at least one renewable energy device for transforming nature energy into electric energy; and an electric energy control device, which connects the renewable energy device to a mains grid and controls storage and output of electric energy of the renewable energy device.

Abstract: Disclosed herein is a process for enhancing anaerobic biohydrogen production, including: adding into a reactor an organic waste containing hydrogen-producing anaerobic bacteria, a first substrate, and a carrier that permits the hydrogen-producing anaerobic bacteria to adhere and grow thereon, so as to form a mixture; acclimating the mixture at a first agitation speed ranging from 5 to 60 rpm, so that the hydrogen-producing anaerobic bacteria adhere to and proliferate on the carrier, followed by the formation of granular biomasses within the acclimated mixture; and feeding a second substrate into the reactor at a second agitation speed ranging from 5 to 60 rpm, so that the content of the granular biomasses is increased while the second substrate is anaerobically fermented by the hydrogen-producing anaerobic bacteria in the granular biomasses to result in the production of hydrogen.
