臭气处理设备的除臭方法

通常,一般环保公司都是采用臭气处理设备进行臭气处理,那么这些臭气处理设备的除臭方法是哪些?接下来,我将简单阐述一下。

恶臭废气处理

植物提取液喷淋法

植物提取液含有大量的多聚糖、活性肽、酶等种类繁多的代谢产物,被喷洒到空间后能直接与空气中的臭气物质反应,使其发生物理或化学上的变化,从而消除恶臭污染。在污水厂内,植物提取液除臭剂主要应用于提升泵房、生物反应池、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。

活性炭吸附法臭气处理设备

活性炭吸附法主要是利用活性炭的吸附作用,使恶臭气体通过吸附剂填充层而被吸附去除。由于运行费用高,活性炭法一般应用于风量较小、臭气浓度较低、出气要求较高的废气处理,也经常作为其它除臭方法的后处理。

植物提取液+生物过滤臭气处理设备

这是一对简单的臭气处理组合工艺,主要适用于臭气收集系统并不完善的污水厂。生物过滤池用于处理收集恶臭,而植物提取液则可喷淋至提升泵房、生物反应池、污泥脱水车间等地处理散发余臭。

化学洗涤+生物过滤臭气处理设备

本组合属于化学法和生物法的联合除臭工艺。其搭配方式有多种,而最完备的组合装备包括臭气导入区、前级(化学)洗涤区、生物滤床过滤区、后级化学洗涤区、净化气体排出区,其中前后两级洗涤区可采用不同的洗涤剂。当污水厂收集臭气气量偏高或气温较低时,生物滤床处理效果下降,两级洗涤区需同时启动,前者对臭气进行除尘及加湿,后者通过化学反应去除生物滤床未除去的恶臭污染物,从而确保达标排放;其它正常情况下,可不激活后级化学洗涤处理。广州猎德污水厂采用化学洗涤一生物滤床联合除臭工艺处理臭气效果显著,NH3去除率大于90%,H2S去除率大于99%。该组合工艺操作灵活、经济高效,具有广阔的研究应用前景。

上海羿清环保是一家专注于生物除臭的环保公司,其生产的生物滤池臭气处理设备能够有效处理恶臭气体,受到业内专业人士的一致好评。
