污水除臭技术有哪些?优缺点是什么?
污水站是汇集来自各个方向的污水、废水。有洗菜、洗衣服的废水,有上厕所冲马桶的污水,还有一些工业排放的废水,而这些污水、废水汇集到一起会产生一些难闻的气体,有的甚至会对人体产生危害,好在有污水除臭技术的出现,而污水除臭技术分好多种,那么哪一种比较好呢?以下是污水除臭技术的种类和比较

污水除臭技术有哪些?优缺点是什么?

        污水站是汇集来自各个方向的污水、废水。有洗菜、洗衣服的废水,有上厕所冲马桶的污水,还有一些工业排放的废水,而这些污水、废水汇集到一起会产生一些难闻的气体,有的甚至会对人体产生危害,好在有污水除臭技术的出现,而污水除臭技术分好多种,那么哪一种比较好呢?以下是污水除臭技术的种类和比较

       一、掩蔽法
        脱臭原理:采用更强烈的芳香气味与臭气掺和,以掩蔽臭气,使之能被人接受。
        适用范围:适用于需立即地、暂时地消除低浓度恶臭气体影响的场合,恶臭强度2.5左右,无组织排放源。
        优点:可尽快消除恶臭影响,灵活性大,费用低。
        缺点:恶臭成分并没有被去除。
        二、稀释扩散法
        脱臭原理:将有臭味的气体通过烟囱排至大气,或用无臭空气稀释,降低恶臭物质浓度以减少臭味。
        适用范围:适用于处理中、低浓度的有组织排放的恶臭气体。
        优点:费用低设备简单。
        缺点:易受气象条件限制,恶臭物质依然存在。
        三、热力燃烧法、催化燃烧法
        脱臭原理:在高温下恶臭物质与燃料气充分混和,实现完全燃烧。
        适用范围:适用于处理高浓度、小气量的可燃性气体。
        优点:净化效率高,恶臭物质被彻底氧化分解。
        缺点:设备易腐蚀,消耗燃料,处理成本高,易形成二次污染。
        四、水吸收法
        脱臭原理:利用臭气中某些物质易溶于水的特性,使臭气成分直接与水接触,从而溶解于水达到脱臭目的。
        适用范围:水溶性、有组织排放源的恶臭气体。
        优点:工艺简单,管理方便,设备运转费用低。
        缺点:产生二次污染,需对洗涤液进行处理;净化效率低,应与其他技术联合使用,对硫醇,脂肪酸等处理效果差。
        五、药液吸收法
        脱臭原理:利用臭气中某些物质和药液产生化学反应的特性,去除某些臭气成分。
        适用范围:适用于处理大气量、高中浓度的臭气。
        优点:能够有针对性处理某些臭气成分,工艺较成熟。
        缺点:净化效率不高,消耗吸收剂,易形成二次污染。
