什么是土壤式生物除臭?
生物除臭是利用生物滤料过滤含有污染物的气体,去除挥发性有机化合物和恶臭污染物的过程。生物过滤介质中含有大量自然产生的微生物,可在安全、潮湿、富氧的环境中将有机物转化为二氧化碳和水,将恶臭污染物转化为无味无臭物。

生物除臭是利用生物滤料过滤含有污染物的气体,去除挥发性有机化合物和恶臭污染物的过程。生物过滤介质中含有大量自然产生的微生物,可在安全、潮湿、富氧的环境中将有机物转化为二氧化碳和水,将恶臭污染物转化为无味无臭物。


生物除臭法


土壤式生物除臭系统由钢筋混凝土、碳钢防腐、FRP等材料制作池体,池体预埋通风管和给排水管;配气管与通风管连接。配气管道为HDPE波纹管、FRP风管、碳钢防腐管之一,配气方式为穿管方式;气体由风机送入,经过一定级配的配气系统,然后均匀分布在由砾石、卵石等组成的扩散层中;扩散层上方为缓冲层,主要由火山岩、陶粒等无机烧结填料组成;生物土层由鹅卵石、当地土壤、陶粒、珍珠岩、火山岩、石英砂和石灰石组成。填充层设置一层或多层,设置湿度传感器检测湿度,实现自动控制和报警;生物土层上方设置草坪和喷灌管道。我们的生物土壤过滤器是根据废气的不同成分和性质制备的。它有一个非常适合微生物活动的环境、培养的微生物群和稳定均匀的气流分布。土壤生物除臭系统最重要的部分是过滤介质。适当建造和维护土壤过滤器是为了创造一个活跃和高效的微生物环境。

土壤层中使用的介质是表层肥沃土壤,尤其是腐殖质土壤。如有必要,需要进行改进,使土壤形成具有吸附作用的胶体颗粒,并增加床层通风。据监测,土层中有大量的细菌、防线菌、霉菌、原生动物、藻类等微生物,每克土壤高达数亿菌类。其中藻类能促进细菌繁殖,细菌是原生动物的饲料。这些微生物构成了一个稳定的生物群落系统,具有很强的分解污染物生物除臭的能力。
