植物提取液除臭剂主要应用于产生恶臭气体且恶臭气体不便于收集的构筑物内,如:
(1)垃圾收集与处理,即垃圾站、垃圾转运站、垃圾压缩站、垃圾填埋场、垃圾处理厂等;
(2)污水收集与处理,即污水提升泵站、污水处理厂、污泥处理厂等其中垃圾站、垃圾转运站,污水提升泵站、以及污水处理厂内堆砂场、污泥装卸车间等,均属于较为分散的臭气发生源,且臭气产生量都不太大,适宜采用天然植物提取液除臭工艺。

三、生物法除臭

1.1生物除臭原理

生物法除臭

SHENGWULVCHIFACHUCHOUGONGYISHIYIZHONGANQUANKEKAODECHULIFANGFA,CHUCHOUXIAOLVDAYU90%,QIYUANLISHICHOUQIJINGSHOUJIXITONGSHOUJIHOUJIZHONGSONGDAOSHENGWULVCHICHUCHOUZHUANGZHICHULI,CHOUQITONGGUOSHIRUN、DUOKONGHECHONGMANHUOXINGDEWEISHENGWULVCENG,LIYONGWEISHENGWUXIBAODUIECHOUWUZHIDEXIFU、XISHOUHEJIANGJIEGONGNENG,WEISHENGWUDEXIBAOGETIXIAO、BIAOMIANJIDA、XIFUXINGQIANG、DAIXIELEIXINGDUOYANGDETEDIAN,JIANGECHOUWUZHIXIFUHOUFENJIECHENGCO2、H2O、H2SO4、HNO3DENGWUDUWUHAIDEJIANDANWUJIWU。

生物除臭主要有三个步骤:

(1)SHUIRONGSHENTOU;

(2)SHENGWUXISHOU;

(3)SHENGWUYANGHUA。

第一步:水溶渗透。滤料表面覆盖有水层,臭气中的化学物质与滤料接触后在表层溶解,并从气相转化为水相,以利于滤料中的细菌作进一步的吸收和分解。另外,滤料的多孔性使其具有超大的比表面积,使气、水两相有更大的接触面积,有效增大了气相化学物质在水相中的传送扩散速率(经实验测试所得,其产生的瞬时效应是化学清洗的几百倍)。所以,水溶渗透过程其实是一物理作用过程,高速的传送扩散意味着滤料可迅速将臭气的浓度降到极低的水平。

第二步:水溶液中的恶臭成分被微生物吸附、吸收,恶臭成分从水中转移至微生物体内。

第三步:通过生物氧化来降解污染物的过程。滤料中的专性细菌(根据臭源的类型筛选而得到的处理菌种)将以污染物为食,把污染物转化为自身的营养物质,使碳、氢、氧、氮、硫等元素从化合物的形式转化为游离态,进入微生物的自身循环过程,从而达到降解的目的。同时,专性细菌等微生物又可实现自身的繁殖,当作为食物的污染化合物与专性细菌的营养需要达到平衡,且水份、温度、酸碱度等条件均符合微生物所需时,专性细菌的代谢繁殖将会达到一个稳定平衡,最终的产物是无污染的二氧化碳,水和盐。从而将污染物去除。
