城镇污水站除臭常用除臭技术
城镇污水处理厂在污水处理过程中产生的恶臭气体主要来源于污水和污泥处理,其物质组成主要有碳、氢和硫元素,主要成分为NH3、H2S、甲硫醇等物质。恶臭气体不仅能刺激人的嗅觉器官使人感觉不愉快,而且能损害人的消化、循环、内分泌和神经系统,对人的精神状况产生不利影响。随着人们公众环境意识的增强,大气恶化问题逐渐得到关注,恶臭气体的妥善处理也成为人们研究的焦点之一。

污水站除臭效果和运行成本
在城市污水处理厂建设时,除污水厂与敏感建筑物之间应有一定防护距离,并设置绿化带等隔离措施外,还需要对臭气经过收集处理达标后排放,而在臭气控制过程中,对散发臭气的构筑物和设备进行加盖密闭既要满足污水处理厂的操作管理要求,又要防止臭气的散发,特别是在构筑物尺寸较大的情况下,选择合适的加盖结构,直接影响到臭气能否有效控制和投资成本。

污水站生物除臭技术
通常污水中,印染废水占85%左右,同时还有15%左右的生活污水及其他各种医药、制革等工业废水,属于典型的综合性工业废水。

生物除臭原理
恶臭是指大气、水体、废弃物等物质中能够引起人体厌恶或不愉快的挥发性气味。是一种通过空气介质作用于人的嗅觉器官而被感知的嗅觉污染。工业和市政污水处理设施中的废水处理池是产生挥发性有机化合物(VOCs)的主要源头,此恶臭属于由废水引起的二次污染。污水处理厂中比较典型的产生VOCs的处理池包括:气浮池、沉淀池、生化池、曝气池、污泥浓缩池等几种类型,由于气体成分的不同,产生的恶臭程度也不相同。

生物除臭处理技术前景
根据国家标准《恶臭污染排放标准》 (GB14554—93)中给出恶臭的定义为:一切刺激嗅觉器官引起人们不愉快及损坏生活环境的气体物质。随着环保要求的严格,国家对污水处理场恶臭气体的治理工作也越来越重视。

物化一生物组合式除臭技术
由于微生物降解污染物需要保持一定的生物量和停留时间,因此对于生物降解慢的物质难以有效地去除。另外,当生物反应器的负荷突然增大时,臭气中的污染物不能及时被微生物降解,易出现排放气体不达标的现象。物化技术和生物技术都有其各自的优点和局限性,通过组合可以发挥各自的优势,有效地去除不同类型的臭气。

真菌生物除臭反应器
真菌生物反应器主要依靠真菌的作用去除臭气中的疏水性或水溶性差的物质。真菌通常具有菌丝,增大了菌体与周围环境接触的表面积。真菌具有坚硬的细胞壁,可在较干燥的环境中生长,水溶性差的物质能够直接与真菌接触并被降解。

常规生物除臭技术
生物滴滤池被认为是介于生物滤池和生物洗涤塔之间的处理技术,臭气中污染物的吸收和生物降解同时发生在一个反应装置内。生物滤池是应用最广泛的生物处理技术,目前己被大量用于污水、污泥以及生活垃圾处理等过程中产生的含硫化氢和氨等恶臭物质的臭气处理。生物洗涤塔可用于控制污水处理厂散发的臭气。使用生物滴滤池处理堆肥产生的氨气,去除率可达94.3%。生物滤池、生物洗涤塔和生物滴滤池各有其特点和应用条件,可根据臭气中污染物的特性和条件,选择适宜的处理技术。
