摘要
污水处理厂产生的城市污泥数量庞大、成分复杂,超临界水气化技术处理城市污泥可以产生H_(2)。介绍了超临界水的特点和超临界水气化过程中发生的主要反应,重点对污泥超临界水气化制氢的影响因素以及产物的安全性进行了综述。此外,针对该技术所存在的问题提出了解决方法,并对未来的研究方向进行了展望。
Wastewater treatment plants generate a large amount of municipal sewage sludge with complex compositions.Hydrogen can be produced in the treatment of municipal sewage sludge by supercritical water gasification technology.The characteristics of supercritical water and main reactions took place in supercritical water gasification treatment process are analyzed.The influence factors for supercritical water gasification treatment of sewage sludge to produce hydrogen and the safety of products are introduced in detail.In addition,available solutions are put forward to the existing problems of this technology,and future research directions are also discussed.
