控制污水中硫化氢的生成──减轻大气污染和设备腐蚀

石油和石化企业所排放的含硫污水给水环境带来的污染是众所周知的，但它对大气环境的间接污染却常被人们忽视。而含硫污水中逸出的硫化氢是引起恶臭的主要原因之一，与水共存时又会对金属设备造成严重腐蚀，因此，控制污水中硫化氢的生成可有效地减轻污水所带来的大气污染和腐蚀现象。

Control of H2S Formation in Waste Water-Reduction in Atmospheric Pollution and Equipment Corrosion

It is well known that sour water discharged from oil and petrochemical enterprises causes pollution of the water environment but its indirect pollution of the at-mospheric environment is often ignored by people.H2S escaped from sour water is one of the principal causes bringing about foul smell,and also causes grave corrosion of metallic equipment while coexisting with water,therefore,control of H2S formation in waste wa-ter can effectively reduce atmospheric pollution and corrosion caused by waste water.
