为了有效地解决污水臭气问题,应综合考虑各方面因素,对水质不同、臭气散发特性不同的污水处理厂应采取不同的处理措施,主要有恶臭源处理和溢气处理两种。

生物除臭在污水站治理中的应用

臭气来源控制

臭气源控制是除臭技术的重要组成部分,它包括臭气源抑制和散发控制。通过投掷适当的化学药剂等方法控制恶臭源抑制剂的状态,可以保证系统的正常运行,减少恶臭污染物的产生。排出控制主要是通过对臭气源集气与排气系统进行设计,以较少的排气量实现良好的排出,控制后续脱臭装置的规模。有效的臭气收集是整个臭气控制的重要一环,可采用以下方法进行臭气收集:封闭臭气源,设置局部吸风口。

溢气治理

治理泄漏气体是除臭的一个重要方面。市政下水道除臭是指恶臭分子通过一定的方法掩盖、吸收、破坏或降解的过程。近几年来,我国污水处理厂除臭技术发展迅速,从传统的物理化学方法和生物法逐步转变为新的生物法,如天然植物液除臭、高能离子除臭法和活性氧氧化法。多种方法的结合已成为一个重要的发展趋势。

生物学方法

生物学方法是利用自然界的微生物和细菌对臭气中的硝化降解作用进行自然除臭,其原理是在适宜的条件下,将收集到的废气通过长满微生物的固体载体,由填料吸收,由微生物氧化分解。去除臭味的过程大致可分为从气相到液相的三个阶段,臭味污染物进入微生物体内,臭味分子作为养分分解利用。生化处理技术具有处理效果好,设备简单,成本低等优点,在城市污水处理厂中应用最为广泛。

生物除臭在污水站治理中的应用

上海羿清环保生物滤池污水站的除臭设备能有效处理各种污水中的臭气,具有节能、高效、环保、不产生二次污染等诸多优点,深受业界好评。
