污水废气处理的影响因素有哪些

污水除臭受到广泛重视,生物除臭被认为是目前具有优势的除臭方法。而填料是决定污水废气处理效果的重要因素。

污水废气处理的影响因素有哪些

填料

填料是影响生物除臭最关键的因素之一。在相同的工况条件下,采用生物除臭技术去除恶臭污染物,选用不同性质的填料,其除臭效果大不相同。大量研究证明,不同性质的填料,其理化性质、挂膜难易程度、生物生长速度、使用寿命大不相同。刘波、羌宁等人对不同填料生物除臭技术的性能进行了研究。性能优良的填料不但具有较高的比表面积、良好的保水性、稳定的理化性质、优异的挂膜性能,还能为生物提供微量营养元素并具有缓冲生物系统pH值的能力。

钙基复合填料生物除臭技术介绍

由于一些恶臭成分的降解会产生酸性物质,如果这些酸性产物未被及时排除将会对生物的活性产生抑制作用。为了稳定控制生物系统的pH值,可采取在填料中添加石灰、大理石、贝壳等钙基填料的方式提高生物除臭系统的缓冲能力。其作用机理是,钙基复合填料是以CaCO3为主体的复合填料,其在运行过程中能够缓慢向水体中释放CaCO3,从而形成缓冲体系。当恶臭污染物浓度较高时,生物代谢产生的酸能够被缓冲体系中和,使pH值稳定在一定范围内,基本一致,但实测噪声值略高于预测值,特别是在300m处,该点距离源强较远,可能实测值受其他声源影响。
