目前,生物除臭受到广泛应用,那么生物除臭具体是怎样的呢?接下来,我将具体介绍一下生物滤池除臭。

生物滤池除臭工艺类型

化学除臭法

该方法利用化学反应通过多级吸收系统,高效、广泛地去除了臭气成分和残余成分,最后经除雾装置后直接排放或混合稀释后排放至大气。该系统可以通过调节加药量和溶液的循环流量来适应气流量和臭气浓度的变化,具有较强的操作弹性,而且反应速度快、耐冲击负荷强,因此可减少臭气对人畜、设备和环境等的损害程度。但此法投资大、运行成本高且易造成二次污染,化学反应后的产物有造成二次环境污染的可能性,需要对洗涤之后的化学产物进行严格处理。

生物滤池

该方法的优点是生物相和液相都不流动,气、液接触面积大,且只有一个反应器,可操作性强,运行费用低;缺点是反应条件较难控制,填料也需要定期更换,占地面积大。对于城市污泥好氧发酵工程而言,由于发酵产生臭气的成分复杂、浓度低、臭气流量大,生物滤池均能实现臭气的去除,且填料更换周期远远长于其他几类工艺,筛分后的好氧发酵产物也可作为非常有效的除臭滤料循环使用,因此生物过滤法在城市污泥高温好氧发酵工程项目中应用前景广阔。

气的扩散空间处理和除臭材料

扩散空问处理工艺可分为催化分解、悬挂式吸附、液态除臭剂喷淋、顶吸罩负压抽风四种方式。对于大型的城市污泥高温好氧发酵工程,发酵仓内经常多个堆体同时运行,运行过程中因为蒸腾和曝气作用会产生大量的水汽和臭气。普通的吸附剂要取得良好的除臭效果,需要架设多级吸收盘,且在吸附过程中极易因为高温、高湿、气量大而饱和。无论是增加现场再生设备还是不断更换吸附剂,都将增加巨额工程投资和人工投入。
