采用洗涤法配合生物法对垃圾站的粉尘及臭气进行治理,同时考虑工艺环境特点,提出了除尘除臭净化塔的改进方案。该技术的具体工艺过程:

垃圾站除臭

(1) 垃圾站地坑的上方设置大小合适、数量分布均匀的抽风口,抽风口的后面安装第一道格网,格网后面是沉降室,格网可以有效拦截粒径大的颗粒,当含尘的恶臭气体经过第一道格网时,在重力和惯性力的双重作用下,粒径大的颗粒会发生沉降;

(2) 粒径小的颗粒在经过第二道格网时,又有部分被拦截,经过两步拦截,大部分粉尘会被去除;

(3)随后废气被风机带入净化塔,在净化塔内废气首先通过自激水冲击的方式进一步去除粉尘,然后利用自激水喷雾形成的均匀水膜,碰撞上升的废气,继续去除粉尘,同时完成部分除臭过程。

废气被带进净化塔后,净化塔主要是利用水雾和生物技术实现除尘除臭。首先,气体进入净化塔后冲击塔内水溶液,形成一道气液混合水幕,废气中剩余的粉尘继续溶于水溶液,同时溶液中的药剂分子与恶臭物质发生化学反应,经过以上过程,废气中的粉尘和恶臭可同时被进一步去除。

废气会继续向上流动至净化塔的填料层,与载体上的填料接触,利用填料上已经接种的生物菌来分解臭气。与此同时,净化塔内的喷淋装置喷出的水雾可吸收部分恶臭气体,水雾也为生物菌的生长创造了良好的环境。类似地,通过第一滤料层后的气体,继续向上流动至第二滤料层,第二滤料层与第一滤料层结构及组成类似,通过相同的生物菌分解和水雾吸附过滤,以达到进一步分解吸收臭气的目的。

上海羿清环保是一家专注于生物除臭的环保公司,其生产的生物滤池垃圾站除臭设备能够有效减少恶臭气体,受到业内人士的一致赞誉。
