我国应用生物技术资源化利用城市剩余污泥的研究进展

Utilization of resource from sewage sludge with biotechnology in China

对我国近年来应用生物技术对城市剩余污泥进行厌氧发酵产沼气、厌氧发酵产氢气、厌氧发酵产生化产品以及污泥堆肥农用等四个领域的研究现状和进展进行了综述。分析发现,厌氧发酵产沼气和堆肥技术比较成熟,得到了比较广泛的应用,而污泥产氢气还处于试验室和中试研究阶段,污泥产生化产品和微生物燃料电池则刚处于起步阶段,具有很大的发展前景。

The current status and progress of utilization and resource of sewage waste sludge by biotechnology in China, including methane production, hydrogen production, biochemicals production and compost production, were analyzed. Currently, methane production and compost production are well developed biotechnology and have been used practically. However, hydrogen production is still in lab scale or pilot scale. The biochemicals production and microbial fuel cell are promising biotechnologies and still in their initial stage.
