污水站除臭有哪些方法
污水处理过程中的恶臭气体主要产生在排污泵站、进水格栅、曝气沉沙池、初沉池等处,以及污泥处理过程中的污泥浓缩、脱水干化、转运等工序。污水处理中的除臭工艺在国外已经有几十年的运营经验,国内也开始兴起并有蓬勃发展的趋势。目前,主要的污水处理除臭技术有活性炭吸附法、热氧化法、生物过滤法等。那么,污水站除臭有哪些方法呢?具体是怎样的?接下来,我将具体介绍一下常见的污水站除臭方法。

污水处理过程中的恶臭气体主要产生在排污泵站、进水格栅、曝气沉沙池、初沉池等处,以及污泥处理过程中的污泥浓缩、脱水干化、转运等工序。污水处理中的除臭工艺在国外已经有几十年的运营经验,国内也开始兴起并有蓬勃发展的趋势。目前,主要的污水处理除臭技术有活性炭吸附法、热氧化法、生物过滤法等。那么,污水站除臭有哪些方法呢?具体是怎样的?接下来,我将具体介绍一下常见的污水站除臭方法。

污水站除臭有哪些方法

活性炭吸附法

活性炭吸附法主要是利用活性炭对臭气的物理吸附作用来除臭的方法。该方法的优点是设备简单,缺点是只适用低浓度、小气量臭气的处理。通常不用作第一级主要除臭装置,而是用作后续的精处理装置。

热氧化法

热氧化法主要是利用高温下的氧化作用将臭气分解成C0,和HO或是部分氧化的方法。该方法的优点是对臭气和挥发性有机化合物非常有效;缺点是投资和运营成本较高,适用于处理重度污染的大型设施的高流、难处理的臭气。目前国内尚未了解到有使用该方法的污水处理厂。

生物过滤除臭法

生物过滤除臭法主要是利用细菌和微生物对臭气的吸收和生物降解过程来自然除臭的方法。该方法的优点是投资适中、见效快、运行成本较低、效率高,是真正的绿色环保方法;缺点是难以确立设计标准,不适合用于处理特高浓度的臭气。

污水站除臭有哪些方法

上海羿清环保生产的污水站除臭设备能够有效处理臭气,而且没有二次污染,是目前许多公司都会采用的环保型臭气处理设备。
