城市污水站中的废气处理
目前,城市生活污水生物处理主要有厌氧、缺氧、好氧处理环节,特别是厌氧处理过程中,需要对大量臭气进行废气处理。这种气味主要是一些硫化物或硫醇类化合物,而且臭气的组成和浓度随污水、污泥处理工艺的不同而变化。

城市污水站中的废气处理

目前,城市生活污水生物处理主要有厌氧、缺氧、好氧处理环节,特别是厌氧处理过程中,需要对大量臭气进行废气处理。这种气味主要是一些硫化物或硫醇类化合物,而且臭气的组成和浓度随污水、污泥处理工艺的不同而变化。

污水站生产过程中产生的臭味对人体造成的危害主要表现在呼吸系统、神经系统、心理等方面。生物学原理,废气生物净化原理是利用反应器内填充物中的微生物,进行代谢,排出的污染物转化为细胞质,硫酸盐,二氧化碳,水,硫酸盐和微生物,废气中挥发性有机污染物分解为二氧化碳,水及其他简单无机物;含硫恶臭污染物中的硫化物在环境中转变为稳定硫酸盐,含有氮的化合物转化为硝酸盐或氮。

 

相对于高耗能、高耗能的化学氧化法,生物法因其经济性,被众多工业废水处理工艺所青睐。目前常用的生物处理方法主要有厌氧和好氧两类,使用这些微生物的代谢能力通过生物降解这些有机和无机物,可以有效去除工业废气中的污染物但对于大风量而言,传统的生物滤池随着设计尺寸的增加、去除能力下降,反应器中的微生物要求有一个适应期,使其应用受到限制。

 

城镇污水处理厂,特别是临近居民区的污水处理厂,臭气对环境和城市社区的影响是一个复杂的问题。要从根本上解决这一问题,必须解决一系列技术、工程投资等问题,有些问题很难在短期内得到彻底解决。

 

要做到这一点,必须城市各管理部门全面协调,加强对废气处理的管理,避免发生纠纷,形成社会不稳定因素。事实上,解决这一问题,有广泛的法理依据,为妥善解决城市污水处理厂臭气排放对环境和城市社区的影响而产生的争议打下了良好的基础。
