厨余垃圾站恶臭废气处理的方法,你get到了吗?
Date﹕2020-11-18|Source:Eclear Environmental
       垃圾站恶臭废气是如何产生的?大家常常有这样的疑问。其实人们在生活中都会产生各种垃圾,尤其是厨余垃圾。像瓜果蔬菜,剩菜剩饭等,这些东西都会被一起放到垃圾站,统一处理,而这些厨余垃圾堆积到一起就会产生浓烈的恶臭废气,让附近的居民都苦不堪言,不仅如此,恶臭废气还会造成周边环境被严重污染。所以,垃圾站恶臭废气处理迫在眉睫,那么,有关垃圾站恶臭废气的影响因素有哪些?又该如何解决这种恶臭废气处理问题呢?下面我们就来分析一下。

垃圾分类点


       厨余垃圾恶臭废气的影响因素

       影响厨余垃圾的发酵产生气味的因素有很多,例如温度、pH值等。不同季节温度的变化是影响发酵的主要因素,夏天的气味要比冬天的气味重一些;不同地区饮食习惯不同,厨余垃圾的组成成份也会发生相应的变化,不同的组成成份,厨余垃圾的pH值也是不同的,不同菌种都有适宜生长的pH环境,研究发现,当pH值控制在4.5~6.0之间时,主要发生的是乙酸性发酵,在这样的环境下,厨余垃圾就会产生刺鼻的酸臭味,主要反应如下:

C6H12O6+2H2O→2CH3COOH+2CO2+4H2

       恶臭废气处理的办法

       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NH3、H2S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CO2和H2O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

          燃烧除臭是比较直接的除臭方法,废气收集后送入焚烧炉,将有机气体通过焚烧的方式生成CO2和H2O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H2S、NH4等需考虑废气中H2S、NH4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。
