摘　　要：针对地下污水处理厂通风和建筑结构的特殊性,结合工程经验及新颁布的《城镇污水处理厂臭气处理技术规程》(CJJ/T 243—2016),对地下污水处理厂除臭工程设计进行总结。地下污水厂除臭应遵循全面收集、分区收集、就近处理、除臭通风合理分工密切配合的设计原则。在沉砂池和周边传动浓缩池采用加罩方式时,应通过合理设计加罩将臭气限定在最小范围内,提高收集效果,降低能耗;结合地下污水厂多立柱且层高受限的结构特点,对地下污水厂风管布置和除臭装置形式进行优化设计;对《城镇污水处理厂臭气处理技术规程》(CJJ/T 243—2016)未明确的构筑物臭气量计算方法提出了补充建议,为设计提供参考。With regard to the characteristic in ventilation and architectural structure of the underground wastewater treatment plants, the underground wastewater treatment plant deodorization project de- sign was summarized according to the project experience and the newly issued specification named Techni- cal Specification for Odor Control of Municipal Wastewater Treatment Plant （ CJJ/T 243 - 2016 ）. The design process should take basis on the following principles： comprehensive collection, sub-regional collection, on-site processing, combination of ventilation and deodorization. Particularly, when the sand settling tank and the peripheral drive condensing tank adopt the cover, the odor should be limited to the minimum range by reasonable design of the cover, so as to improve the collection effect and reduce the energy consumption. Combined with the structural characteristics of multiple columns and limited height of underground wastewater treatment plant, the air pipe arrangement and deodorization device form of underground wastewater treatment plant were optimally designed. Moreover, several supplementary suggestions were put forward on the calculation methods of odor gas emissions for some structures, which were not clarified in Technical Specification for Odor Control of Municipal Wastewater Treatment Plant （CJJ/T 243 - 2016 ）.
