城市下水道硫化氢防治技术研究进展

城市下水道硫化氢造成的危害日益严重，常见的硫化氢治理药剂包括氧气、过氧化氢、次氯酸钠、三氯化铁和硫化亚铁等，但治理成本较高。近年来通过化学和生物处理方法治理硫化氢的研究取得了一些进展。介绍城市下水道系统中硫化氢防治技术方面的研究现状，微生物燃料电池和噬菌体将在今后城市下水道硫化氢治理中发挥重要的作用。

Research progress in prevention and control technology of hydrogen sulfide from urban sewer

The hydrogen sulfide from urban sewer does increasingly serious harm to the environment.The common treatment agents for hydrogen sulfide removal include oxygen,hydrogen peroxide,sodium hypochlorite,ferric chloride and ferrous sulfate,etc.The shortcoming of the control method of sewer hydrogen sulfide is high cost.The treatment of hydrogen sulfide in the sewage treatment system by using chemical and biological methods has made some important progress in recent years.The research status of current and new technology of hydrogen sulfide emission control in sewer systems was introduced in this paper.Microbial fuel cells and bacteriophage for the treatment of hydrogen sulfide from urban sewer will play an important role in the future.
