目前恶臭废气处理受到广泛关注,相应的除臭技术也迭代产生,有很多恶臭废气处理技术种类可供使用。接下来,我将具体介绍一下常见的恶臭废气处理技术种类。

恶臭废气处理技术种类

物理处理法

掩蔽法通常是采用更强烈的芳香气味,或其他令人愉快的气味与臭气掺合,以掩蔽臭气或改变臭气的性质,使气味变得能够为人们所接受,或采用一种能够抵消或中和恶臭的添加剂,以减轻恶臭。掩蔽法的效果因个人各异的感觉程度而有差异。稀释扩散法是将有臭味的气体由烟囱排向高空扩散,或者以无臭的空气将其稀释,以保证在烟囱的下风向及臭气发生源附近的人们不受恶臭的侵扰,不妨碍人们的常生活。通过烟囱排放臭味气体,必须根据当地的气象条件,正确设计烟囱的高度,其目的是保证有人工作和生活的地点,恶臭物质的浓度不超过它的阈值浓度。当以烟囱排放含有的恶臭废气,不能保证下风向地面最大浓度低于阈值浓度时,可考虑掺和清洁空气适当稀释后排放。

生物法

生物法是利用微生物的代谢作用,使气体在通过生物处理装置时,其中的恶臭物质被溶于水,继而为微生物所降解。其实质是利用微生物的生命活动,将气流中产生气味的物质转化成简单的无味物质。现阶段的主要工艺包括:生物过滤法、生物滴滤法以及生物洗涤法。生物洗涤塔适宜于处理净化气量较小、浓度大、易溶且生物代谢速率较低的废气;对于气量大、浓度低的废气可采用生物过滤床而对于负荷较高以及污染物降解后会生成酸性物质的,则以生物滴滤床为好。

恶臭废气处理技术种类

生物法具有安全性好、无二次污染等特点,尤其在处理低浓度、易生物降解的恶臭时更显其经济性,具有广泛的应用前景。上海羿清环保公司是一家专注恶臭废气处理方案设计和设备生产的环保公司,其生产的生物滤池恶臭废气处理设备能够有效处理废气,无二次污染,更加环保。
