生物滤池的除臭气体来源及成分
一般地,城镇污水处理厂的恶臭气体来源于两类:一类是直接从污水中挥发出来的有机组分,另一类是微生物对有机物降解过程中产生的还原性代谢产物。恶臭气体的成分繁多,其中硫化氢、氨气、硫醇和挥发性脂肪酸是产生臭味的主要物质。

一般地,城镇污水处理厂的恶臭气体来源于两类:一类是直接从污水中挥发出来的有机组分,另一类是微生物对有机物降解过程中产生的还原性代谢产物。恶臭气体的成分繁多,其中硫化氢、氨气、硫醇和挥发性脂肪酸是产生臭味的主要物质。

生物滤池的除臭气体来源及成分

臭气体的现有处理方法

恶臭气体的处理方法主要有:吸收法活性炭吸附法、化学氧化法、燃烧法、等离子体分解法、光催化氧化法、天然植物提取液喷洒技术和生物除臭法等。

受技术、投资和运行费用的影响,当前城镇污水处理厂恶臭气体采用的处理方法主要有吸收法、化学氧化法、等离子体分解法和生物除臭法。其中生物除臭法是20世纪50年代后期发展起来的恶臭气体处理方法,具有处理效率高、无二次污染、设备简单、便于操作、投资适中、运行费用低廉和管理方便的特点。

物除臭原理

生物除臭主要分为三个步骤:第一是将部分恶臭气体由气相转变为液相的传质过程;第二是溶于水中的恶臭气体通过微生物的细胞壁和细胞膜被微生物吸收,不溶于水的恶臭气体先附着在微生物体外,由微生物分泌的胞外酶分解为可溶性物质,再渗入细胞;第三是恶臭气体进入细胞后,在体内作为营养物质被微生物分解、使用,使恶臭气体得以去除。

上海羿清环保公司就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臭气,而且不会产生二次污染,受到业内人士的一致好评。
