餐厨垃圾处理站恶臭气体处理工程设计与运行

Design and operation of deodorization engineering in a food waste processing station

采用组合式生物除臭技术对北京市通州区某餐厨垃圾处理站产生的恶臭气体进行处理,结果表明,在工程稳定运行期,氨和硫化氢的去除效率分别达99%和98%,出气浓度分别为0~0.22 mg/m^3和0~0.19 mg/m^3,达到北京市《大气污染物综合排放标准》(DB 11/501—2017)排放要求。工程投资和运行费用低、维护和运行管理方便,运行过程无二次污染物产生。

The combined biological deodorization equipment was developed to treat odors emitted from a food waste processing station in Tongzhou district of Beijing city.The results showed that the removal efficiencies of ammonia and hydrogen sulfide were 99%and 98%,respectively,and the outlet gas concentrations were 0~0.22 mg/m 3 and 0~0.19 mg/m 3,respectively,when the combined biological deodorization device was in stable operation period,which could reach the emission requirements of Beijing Comprehensive Emission Standard of Atmospheric Pollutants(DB 11/501—2017),when the biological deodorization device was in stable operation.The project had advantages of low investment and operating costs,convenient maintenance and operation management,and no secondary pollutants produced.
