在对国内污水处理厂除臭技术调查的基础上,分析了目前污水处理厂除臭技术存在问题,对常用的几种除臭技术进行了技术经济综合比较;并针对我国除臭技术的研究和发展现状,提出宜采用组合式除臭技术处理污水处理厂的恶臭污染。  相似文献   

H2S Emissions from a Submerged Pilot‐Scale Fixed Bed Biofilm Reactor

A study was performed in two submerged, pilot‐scale biofilm bioreactors operated under different conditions to determine the relationship between the operating parameters and H₂S emission. H₂S was always detected in the exhaust air at concentrations varying from 1 to 353 ppm_v. The specific aeration rate was the most influencing parameter, with As < 30 kg COD (dissolved oxygen concentrations <4 mg L^?1) increasing noticeably the H₂S production. The periodical removal of the accumulated sludge reduced H₂S emissions by ～14%.  相似文献
