近年来,随着人口的快速增长、城市化的不断扩张,作为公共服务设施的医院也在不断改扩建中,作为医院配套设施的污水处理站也越来越收到人们的关注。

污水站除臭—双离子除臭技术应用原理

污水站尾气的来源

污水站区内尾气的来源主要为:①格栅:格栅的臭气则是由于渣的积累和刮渣机的运行造成的。②污水预处理装置,如预搅拌调节池。如果进水BOD浓度较低,会造成缺氧,将产生大量还原性恶臭物质;另外预搅拌空气搅动也带动的气体的扩散问题。③污水生化处理装置,处于充氧状态的曝气池气体外溢产生臭气扩散。污水处理系统中采用厌氧水解,产生的臭气更是不可避免的。

尾气的产生的危害

尾气通过嗅觉系统影响人休健康。嗅觉是由鼻腔上部感觉细胞产生兴奋,在传人大脑皮质而产生活动的结果,尾气污染除了对嗅觉产生影响引起心理厌恶外,还会产生某些身体上的不适,常见的症状有恶心、头痛、食欲不振。其中对人类危害较大的恶臭物质有硫化氢、氨、甲基胺、苯乙烯和酚类等50多种。尾气除对人体产生危害外,不少臭源还会滋生蚊蝇,造成疾病传播。

双离子除臭技术应用原理

双离子空气净化系统是国外的高新技术,它能有效地清除空气中的细菌、可吸入颗粒物、硫化合物等有害物质。其工作原理是置于设备内的离子发生装置发射出高能正、负离子,它可以与空气当中的有机挥发性气体分子(VOC)接触,打开VOC分子化学键,分解成二氧化碳和水;对硫化氢、氨同样具有分解作用;离子发生装置发射离子与空气中尘埃粒子及固体颗粒碰撞,使颗粒荷电产生聚合作用,形成较大颗粒靠自身重力沉降下来,达到净化目的;发射离子还可以与室内静电、异味等相互发生作用,同时有效地破坏空气中细菌生存的环境,降低室内细菌浓度,并将其完全消除。
