Application of Full Process Odor Control Technology in All Underground WWTP
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 m3/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.
