恶臭废气处理的其他方法

目前,常用的恶臭废气处理方法已经得到广泛应用,那么,还有其他的恶臭废气处理方法吗?接下来,我将具体介绍一下。

恶臭废气处理的其他方法

光催化氧化法

光催化氧化法始于20世纪60年代,90年代广泛应用。目前世界上光催化氧化研究最好的是日本,其次是美国和中国。光催化降解技术原理是光催化剂如二氧化硅在紫外线的照射下被激活,使生成OH自由基,然后OH自由基将恶臭氧化成二氧化碳。用TIOZ催化剂时可采用普通的荧光灯为光源来消除恶臭和非常低浓度的污染物。受催化剂降解效率的影响,光催化氧化法在工业上的应用还待开发。

吸收法

当恶臭气体在水中或其它溶液中溶解度较大,或恶臭物质能与之发生化学反应时,可用液体吸收法治理。恶臭气体常见吸收剂有苛性钠、次氯酸钠、硫酸、盐酸、亚硫酸钠等。

吸收液从塔顶部进入喷淋到填料上,顺着填料滴流;恶臭气体从吸收塔底部进入,通过孔隙空间向上运行;气、液相之间的这种对流方式产生湍流,增大了表面接触面积;吸收液与恶臭气体充分接触后降落至吸收塔的下部。溶液饱和后被收集进入分离塔,经处理去除污染物后溶液再循环使用。净化后的气体从吸收塔顶部排放。

恶臭废气处理的其他方法

上海羿清环保主要采用生物除臭技术进行臭气处理,其生产的生物滤池恶臭废气处理设备能够有效处理臭气,而且没有二次污染,受到业内人士一致好评。
