污水处理厂恶臭治理
污水处理厂恶臭现有治理方法按处理进程可分为预处理、主处理、深度处理。预处理主要有物理和化学方法,如掩蔽法和水洗涤法;主处理有化学方法、物理化学方法和生物方法,如化学药剂法、生物降解法(生物滤池、活性污泥法、土壤除臭法等)、吸附法等

污水处理厂恶臭治理

目前我国污水处理厂恶臭治理方案主要有分散收集、集中处理和就地分散处理2种。

分散收集、集中处理:即将各构筑物中臭气统一收集,送到除臭系统集中处理;

就地分散处理:即根据各构筑物中恶臭浓度的不同分别采用不同原理的除臭装置加以处理。

若污水处理厂规模较大,恶臭浓度大,则分散收集、集中处理可节省建设恶臭治理设施费用及运行费用,降低处理成本。但分散收集的输送管道较多,相应的压力损失也就增大,因此必须确保各管段的密封性。如果污水处理厂水质复杂,各恶臭产生源相距较远且浓度差异很大,则就地采用不同方法处理可缩短输送管道距离,提高除臭效率,减少单机设备负荷,降低设备故障事故。
