1、摘要目前,我国城市污水处理厂的建设很少考虑臭气的处理问题,但随着人民生活水平的提高,对环境质量的要求越来越高,对恶臭气体所带来的污染也更加敏感,有关污水处理设施臭气影响市民生活质量和健康的投诉案例屡见报端,呈上升的趋势。在污水处理过程,保护和提高处理现场及周围的环境,减少恶臭影响,如何对恶臭进行有效控制已成为急需解决的课题。为了保护和提高各类处理现场及周围环境卫生质量,减少对空气造成二次污染,对恶臭进行有效的控制已势在必行。本文介绍了城市污水处理厂恶臭气体的主要成分和污水厂的气味分布情况,主流的处理恶臭技术方法:湿式洗涤法、活性炭吸附法、臭氧处理法、焚烧法、生物洗涤法、掩蔽剂法等,而生物滤池除
2、臭法具有设备少、操作简单、不需外加营养物、投资运行费用低、除臭效率高等特点而受到越来越广泛的重视。该处理量10万m3/d污水厂产生的恶臭浓度为4000,适合生物滤池法的处理浓度要求。 本文阐述影响生物滤池除臭法的因素和滤料的选择,生物滤池除臭法的设计过程和施工运行费用。关键词: 污水处理厂,恶臭,生物滤池AbstractAt present, Chinas urban sewage treatment plant building rarely consider the smell of dealing with the problem, but as the peoples standard
