生物滤池设备系统介绍
生物滤池设备技术采用生物分解法,臭气通过吸气管连接到生物除臭装置,混合气体通过生物过滤器时,与附着在填料上的生物接触,生物体通过自身的生化反应吸收混合气体中的恶臭成分,转化为二氧化碳、水,维持生物体的新陈代谢。

焦化污水站生物滤池

          羿清环保小编和大家聊的生物滤池设备中机械过滤有哪些,希望能对大家有所帮助。

1.1恶臭的来源和危害。

污水处理、污泥处理和垃圾处理设施是臭气的重要来源。废水处理过程中,不同的处理设备和工艺会产生各种各样的臭气。污水处理装置进水泵房产生的主要气味是硫化氢,厌氧消化过程中产生的气味主要是硫化氢等含硫气体,污泥消化稳定过程中会产生氨等挥发性物质。好氧消化和污泥干燥过程可能产生少量硫化氢,但主要产生硫醇和二甲基硫气体。

恶臭对人体呼吸、消化、心血管、内心泌及神经系统都会造成影响。高浓度的恶臭还可使接触者发生肺水肿,甚至窒息死亡。臭味污染常伴随着甲醛和苯等对人体有直接危害的物质,吸入后具有很强的致癌作用。同时,内分泌系统的分泌功能障碍也会影响身体的代谢活动。氨和醛对眼睛有刺激作用,导致眼泪、疼痛、结膜炎、角膜浮肿等。

1.2 国家对恶臭的法规要求

经处理后的废气应符合 GB14554-93 《 恶臭污染物排放标准 》,具体数值参见下表:

恶臭污染物厂界标准值

1.3 臭气处理系统基本原理

在适当的环境条件下,附着在生物填料上的微生物利用废气中的污染物作为能量,维持生命活动,分解成CO2、H2O和其他无机盐类,净化废气。恶臭废气+微生物→CO2+H2O+生物组份 

1.4 工艺说明

生物滤池设备技术采用生物分解法,臭气通过吸气管连接到生物除臭装置,混合气体通过生物过滤器时,与附着在填料上的生物接触,生物体通过自身的生化反应吸收混合气体中的恶臭成分,转化为二氧化碳、水,维持生物体的新陈代谢。
