An Engineering Example of Deodorization for Municipal Sludge Drying System by Quality Separation Method
In order to effectively solve the problems of difficult control and high investment of municipal sludge drying odor,we adopted a method of quality separation,collected and efficiently controlled 80,000 m3/h odor pollutants of sludge drying system from a city in Southern China.This essay introduces the project background,process flow,the core equipment design,equipment operation effect,project investment and operation cost.The operation results showed that the average operating air volume of the high-concentration deodorization was 41439 m3/h,and 40,922 m3/h for the low-concentration deodorization.In addition,the high and low concentration deodorization emission met both the unit border fugitive and the organized emissions standard.The total construction cost was about 15~17 million yuan,and the operation cost was about 20~23(yuan/h)/(m3/h).Overall,the controlling system has good controlling effect on the odor pollutants of sludge drying system,and the system has steady operation,which can provide a reference for other deodorization for sludge drying system.
