臭气全流程治理技术在全地下水质净化厂的应用

Application of Full Process Odor Control Technology in All Underground WWTP

以深圳市全地下水质净化厂——洪湖水质净化厂预处理区和生化区臭气为研究对象,文中结合地下水质净化厂的特点及不同水处理段的臭气浓度特征,采用全流程臭气治理技术,对项目臭源点全识别封闭、臭气全输送、多种处理工艺高效组合治理。总体采用生物法处理,整体除臭规模为95 000 m^(3)/h,系统运行智能简便、运营成本较低。对投产运行后2年的臭气污染物监测数据分析,臭气监测值远低于《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级标准值,处理效果优于预期除臭目标。

The odor in the pretreatment unit and biochemical unit of Honghu wastewater treatment plant(WWTP),an underground WWTP in Shenzhen is studied in this paper,based on the characteristics of WWTP and odor concentration characteristics of different water treatment sections,the whole process odor treatment technology has been adopted,and carried out the odor source points identification and sealing,odor transportation and multiple treatment processes.The overall oder is controlled by biological method,the deodorization scale is 95000 m^(3)/h,the system operation is intelligent and simple,low operating cost.According to the analysis of odor pollutant monitoring data for 2 years after operation,the odor monitoring values are much lower than the first level standard values of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918—2002),and the treatment effect is better than the expected deodorization target.
