Abstract

A method of increasing an anaerobic biological hydrogen production yield from organic waste water or waste is disclosed. According to the method, a magnetic field with certain intensity is evenly disposed on the outer wall of a traditional anaerobic hydrogen-producing reactor by means of permanent magnets or electrified coils, or a proper amount of a magnetic carrier material is added into the hydrogen-producing reactor and adopted as a carrier to which hydrogen-producing bacteria are attached, and temperature and a primary pH value of the organic waste water or the waste fed into the hydrogen-producing reactor are controlled, thus enhancing natural selection of anaerobic mixed flora, promoting culture and enrichment of anaerobic bacteria and improving biological activity and settling performance of the hydrogen-producing bacteria, and therefore objectives of efficiently enriching the hydrogen-producing bacteria and efficiently producing hydrogen from the organic waste water or the waste are achieved under a condition that inoculated sludge and the organic waste water are free of pretreatment.

Description

technical field [0001] The invention belongs to the field of organic waste water or waste treatment technology and clean energy, and specifically relates to an intensified method in the technology of utilizing organic waste water or waste anaerobic fermentation to produce new energy hydrogen. Background technique [0002] Hydrogen is a safe, clean, efficient and environmentally friendly renewable energy, and an ideal substitute for fossil energy. Anaerobic biological fermentation hydrogen production technology has attracted extensive attention due to its advantages of economy, simple operation, wide range of raw materials, and energy recovery from organic wastewater or waste. However, the anaerobic fermentation hydrogen production process is restricted and affected by various environmental factors and the amount of hydrogen-producing dominant bacteria in the inoculated sludge. Whether it can maintain enough hydrogen-producing dominant bacteria in the anaerobic fermentation r...
