固体废弃物处理与产氢技术

Solid Wastes Treatment Process and Biohydrogen

摘要:

氢气能作为一种清洁能源和工业上的原料所使用。目前国际上氢气的获得主要有化学制取和电解水制取两种方法, 但这些方法都需要耗费大量的能源, 特别是化学制取法在耗能的同时还极易对环境造成污染。相比之下, 生物制氢有着极大的优势, 它主要是通过微生物发酵或者光合微生物的作用, 将有机废弃物进行分解从而获得氢气。利用废弃物制氢即可以低廉的获得氢能源同时又能资源化利用废弃物。以下对固体废弃物的类型、产氢的方法等进行了综述。

Abstract:

As a clean energy source and industrial material, hydrogen is very valuable. Electrolysis of water and chemical methods are well-known for producing hydrogen, however, all of these methods need additional energy supply. Besides highly energy cost, the chemical methods will lead to serious environment pollution. Compared with traditional methods, biological production of hydrogen has showed significant advantages. Bio-hydrogen can be produced by anaerobic and photosynthetic microorganisms during treatment of organic waste. It provides a low cost method for producing hydrogen gas, and a way of utilizing waste at the same time. This paper summarized the procedures of treatment of solid waste and the production of bio-hydrogen.
