近年来,生物除臭技术以其工艺相对成熟、基建费用低、操作维护简单、无二次污染等特点而在实际应用中逐渐推广,已成为城市污水厂臭气处理的主流工艺。那么,生物除臭处理装置有哪几类呢?接下来我将具体介绍一下。

生物除臭

生物洗涤器

生物洗涤器通常由一个装有填料的吸收塔和一个具有活性污泥的再生反应池构成,生物悬浮液经喷淋柱从吸收塔顶部向下喷淋,废气中的污染物被填料表面的水吸收后转入液相,然后被水带进再生反应器,通过微生物的氧化作用最终得以去除。生物洗涤法可以处理大气量的废气,压降低,填料不易堵塞,操作处理单元容易控制,生物量累积能保证有效的污染物降解能力;但设备多,成本较高,需要额外投加磷、钾等营养物质,不适合处理低浓度的恶臭污染物。此外,该装置的处理能力依靠气体的溶解,只能有效处理溶解度较高的污染物。目前,该装置在污水厂的实际应用较少。

生物滤池

生物滤池脱臭是研究最早、工艺最成熟、最常用的方法。生物滤池由于生物相和液相都不流动,只有一个反应器,气、液相接触面积大,所以运行费用低,不需外加营养物,处理效率高,适合处理流量大、含硫化合物浓度低的废气。目前,生物滤池在市政污水处理厂的臭气治理中得到了广泛应用。但是生物滤池占地面积大,对高浓度的恶臭气体、复杂的混合气体处理效果不佳。
