垃圾站恶臭气体的主要来源有哪些?
我国的城市生活垃圾可以分为可回收垃圾、有害垃圾、厨余垃圾和其他垃圾。可回收垃圾主要包括一些废塑料、废纸等可回收利用的废物;有害垃圾主要是一些可能给人体或环境带来潜在风险的垃圾,例如废电池;厨余垃圾主要在家庭及饭店在做饭过程中产生的果皮、剩菜剩饭等。

垃圾站恶臭气体的主要来源有哪些?

       我国的城市生活垃圾可以分为可回收垃圾、有害垃圾、厨余垃圾和其他垃圾。可回收垃圾主要包括一些废塑料、废纸等可回收利用的废物;有害垃圾主要是一些可能给人体或环境带来潜在风险的垃圾,例如废电池;厨余垃圾主要在家庭及饭店在做饭过程中产生的果皮、剩菜剩饭等。其中厨余垃圾是恶臭气体产生的主要来源。厨余垃圾主要是由有机成份组成的,尤其在夏天,大量堆积的厨余垃圾在高温作用下,经过发酵,CH4、H2S、NH4等具有刺激性气味的气体释放出来,对周边环境带来污染,给人体带来不适感。

       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
