生物滤床除臭的原理与工艺流程是怎样的?

       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。

生物滤床除臭


       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。

       对污水处理厂常用的几种恶臭处理技术进行技术经济因素综合比较分析,以寻找高效率、低能耗、无二次污染的除臭技术,为城市污水处理厂选择除臭系统提供科学依据。而现在在除臭中,人们使用生物滤床除臭还是较多的,那么生物滤床除臭的原理是什么呢?

       生物滤床除臭原理是将气体收集并加湿后通过管道输入生物滤床底部并使其扩散于土壤内,臭气中多种污染成分溶于水后吸附于土壤颗粒表面。经过一段时间在土壤颗粒表面可逐渐培养出针对致臭物质的微生物,并可不断将致臭物质分解,完成脱臭。

       生物滤床法的工艺流程为:臭气收集→风管输送→抽风机→预洗池加湿→生物滤池→排气。滤床填料可采用海绵、干树皮、干草、木渣、贝壳、果壳及其混合物等。广州猎德污水处理厂采用洗涤-生物滤床联合除臭工艺对污泥浓缩池、脱水间臭气进行处理,NH3去除率大于90%,H2S去除率大于99%。
