污水除臭技术选择
随着社会经济的发展、生活水平的提高和公众环境意识的日益增强,城市污水处理厂的恶臭污染也就成为亟待解决的首要问题。因此在建设污水处理厂的过程中,除了设置必要的污水、污泥处理与处置系统外,还需针对污水处理厂臭气物质的成分和臭气的强度,选择合适的除臭技术,设置经济有效的除臭系统。 1、生物滤池 生物滤池主要包括增湿器和生物处理装置两部分。由引风机收集的臭气经增湿装置预处理(有的预处理还包括温度调节、去除颗粒物等)后进入生物处理装置,气体中的污染物从气相主体扩散到填料外层的水膜并被填料所吸附,最终降解为二氧化碳、水等,处理后的气体从生物滤池的顶部排出。生物滤池的填料层是具有吸附性的滤料(如土壤、堆肥、活性炭等)。堆肥生物滤池因其较好的通气性和适度的通水和持水性,以及丰富的微生物群落,能有效地去除烷烃类化合物如丙烷、异丁烷,对酯及乙醇等生物易降解物质的处理效果更佳。 2、植物提取液除臭 植物提取液除臭的机理为臭气中的异味分子被喷洒分散在空间的植物提取液液滴吸附,在常温下发生各种反应,生成无味无毒的分子。在污水厂中,植物提取液除臭剂主要应用于提升泵房、生

随着社会经济的发展、生活水平的提高和公众环境意识的日益增强,城市污水处理厂的恶臭污染也就成为亟待解决的首要问题。因此在建设污水处理厂的过程中,除了设置必要的污水、污泥处理与处置系统外,还需针对污水处理厂臭气物质的成分和臭气的强度,选择合适的除臭技术,设置经济有效的除臭系统。

污水除臭技术选择

1、生物滤池

生物滤池主要包括增湿器和生物处理装置两部分。由引风机收集的臭气经增湿装置预处理(有的预处理还包括温度调节、去除颗粒物等)后进入生物处理装置,气体中的污染物从气相主体扩散到填料外层的水膜并被填料所吸附,最终降解为二氧化碳、水等,处理后的气体从生物滤池的顶部排出。生物滤池的填料层是具有吸附性的滤料(如土壤、堆肥、活性炭等)。堆肥生物滤池因其较好的通气性和适度的通水和持水性,以及丰富的微生物群落,能有效地去除烷烃类化合物如丙烷、异丁烷,对酯及乙醇等生物易降解物质的处理效果更佳。

2、植物提取液除臭

植物提取液除臭的机理为臭气中的异味分子被喷洒分散在空间的植物提取液液滴吸附,在常温下发生各种反应,生成无味无毒的分子。在污水厂中,植物提取液除臭剂主要应用于提升泵房、生物处理池、污泥脱水车间等产生恶臭气体且恶臭气体不便于收集的构筑物内。

3、高能离子除臭

高能离子净化系统工作原理是置于室内的离子发生装置发射出高能正、负离子,它可以与室内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。

生物除臭

生物滤池系统在欧洲诸国应用于医院、办公楼、公众大厅等,以空气净化以致达到模拟自然森林空气清新的效果。近些年逐步开发应用于污水处理厂和污水提升泵房的脱臭方面,法国、英国、苏格兰、瑞典等国的应用实例很多。

上海羿清环保科技有限公司,专注于恶臭废气处理,自主研发国际领先的光催化剂和除臭催化剂等核心技术,在各行业积累了丰富的治理经验,并不断开发和完善满足不同行业客户需求的一站式废气综合解决方案。
