生物除臭设备从字面意思上就可以知道是通过生物的方法进行除臭的一种除臭装置,那么,从工艺的角度来说,这类生物除臭设备的原理是什么呢?

一、生物滤池臭设备概述

      生物滤池除臭设备:是以生物填料为载体,使微生物在适宜的环境下,在生物填料表面形成生物膜,生物膜中的微生物利用废气中的无机和有机物作为碳源和能源,通过降解恶臭物质维持其生命活动,并将恶臭物质分解成二氧化碳、水、矿物质等无臭物,达到净化恶臭气体的目的。

       二、工艺流程

       恶臭气体收集装置预处理装置生物过滤装置抽风机达标排放

       三、流程说明

       恶臭气体经过管道收集后进入预处理装置,经水洗加湿使废气的湿度达到90%以上,湿气体再进入生物过滤除臭装置,气流与循环液在穿过生物填料层的过程中完成生物的气液扩散、液固扩散、生物氧化三个过程,生物填料表面生物膜中的微生物以恶臭气体物质为营养,恶臭物及VOCs被微生物氧化分解,在转化过程中产生能量,为微生物的生长与繁殖提供能源,使恶臭气体物质的转化持续进行,经净化后的气体由引风机引出排放。

       循环液中含有脱落的生物膜和微生物,经过滤、补充新鲜洗涤液后循环使用,过滤去掉多余的少量生物膜作为污泥定期排放。

        四、系统特点

       1、 全自动控制,性能稳定,无须专人操作;

       2、 使用久性生物填料,微生物能够依靠洗涤液中的养份和气体中恶臭物质生长,无须另外投加营养剂。生物膜生态条件稳定,单位体积内生物量大,微生物菌群具有较高的生物吸附和生物氧化的能力,抗冲击能力强,分解恶臭物质的速度快、效率高;

      3、塔体采用模块式结构,可现场施工,便于安装;

      4、独特的气体分布方式,分布均匀,净化效率高达90%以上。

适用领域: 污水处理、垃圾处理、饲料加工、粪便处理、制药系统等过程产生的含有硫化氢﹑氨﹑硫醇﹑硫醚等恶臭气体的处理。

适用场所:1    污水处理厂预处理、生物处理、污泥处理进行恶臭气体的净化和办理。2    垃圾处理过程中的堆放、分拣、堆肥、埋、焚烧以及垃圾渗透液污水处理站恶臭气体的净化和办理。3    涂料与喷漆、炼焦、制药、橡胶塑料、染印皮革、有机染料及组成材料厂和发酵制药、石油化工、制鞋厂、印刷厂、造纸厂、畜牧饲养、饲料加工、粪便处理等恶臭气体净化和办理。

以上就是关于生物除臭设备以及一些相关知识的介绍,如果您仍然还存在一些方面的疑问,欢迎咨询。
