随着城市垃圾污水产生大量臭气,严重影响人们的日常生活。那么,恶臭废气处理的工艺类型有哪些呢?具体是什么?接下来,我将具体介绍一下常见的恶臭废气处理的工艺类型。

恶臭废气处理的工艺类型

液体吸收法

化学吸收法是采用碱液、酸液等,将气体中带气味的无机类物质通过洗涤的方式去除,吸收的主要是像NH3H2S等具有酸碱性的气体,其原理是酸碱中和反应,该方法适用于高浓度恶臭气体,并能够有针对性的处理某种恶臭气体,技术比较成熟,弊端是对中性的有机成份不能起到很好的吸收效果,未端还需连接其他的治理设施。

光氧催化除臭法

UV光解除臭是在臭氧存在的环境下,采用特定波段的高能紫外线光束进行照射,在催化剂的作用下分解为CO2H2O的过程。对氨、乙酸丁酯、三甲胺、二硫化碳、二甲二硫、甲硫氢、甲硫醇、甲硫醚、乙酸乙酯和苯乙烯、硫化物H2S,VOC类具有非常好的裂解效果。这种除臭方法具有效率高、无需填加吸附介质、去除种类多、设备占地面积小等优势。

燃烧除臭法

燃烧除臭是最直接的除臭方法,废气收集后送入焚烧炉,将有机气体通过焚烧的方式生成CO2H2O后排放。该种除臭方法对有机成份具有很好的除臭效果,燃烧充分后对环境基本不会产生影响,对无机的H2SNH4等需考虑废气中H2SNH4所占比例,如果比例很高的话还需在末端连接脱硫脱氮设备。燃烧除臭法具有耗能高、运行费用大、设备占地面积大的特点。

恶臭废气处理的工艺类型

上海羿清环保是一家专注于生物除臭的环保公司,其生产的生物滤池恶臭废气处理设备能够有效处理恶臭气体,而且不会产生二次污染,受到业内人士的一致赞誉。
