广东省《城镇地下污水处理设施通风与臭气处理技术标准》的编制思路

Thoughts of Compiling Guangdong Technical Standard for Underground Municipal Wastewater Treatment Plant Ventilating&Odor Controlling System

对正在编制的广东省标准《城镇地下污水处理设施通风与臭气处理技术标准》主要内容进行了介绍,包括压差控制、设置缓冲间、臭气风量、气流组织、主要恶臭污染物室内外排放指标、防烟排烟设计等方面的规定,以及最基本的节能措施等。该标准考虑了地下污水处理厂现状与发展趋势,从工艺、建筑、风、水、电等方面做好对恶臭污染源的监测、控制与臭气处理,避免不同区域之间臭气的扩散。该标准在地下污水处理设施内外部空气环境控制效果方面做出了目前我国现有标准规范中最严格的规定,体现了对地下污水处理厂的臭气处理只有在设计、建设、运营等各个环节全过程中严密控制才能满足要求的编制思路与特点。

The main contents of Guangdong Technical Standard for Underground Municipal Wastewater Treatment Plant Ventilating&Odor Controlling System being compiled is introduced,including the differential pressure control,buffer room setting,odor air volume,air diffusion,indoor and outdoor emission indexes of main odor pollutants,smoke control and exhaust design,as well as basic energy saving measures,etc.This standard takes into account the current situation and development trend of underground wastewater treatment plants,and does a good job in monitoring,controlling and treating odor pollution sources from the aspects of technology,architecture,ventilating,water and electricity,so as to avoid the diffusion of odor between different areas.The standard has made the most stringent provisions in the existing standards and specifications in China in terms of the control effect of internal and external air environment of underground sewage treatment facilities,which reflects the compilation ideas and characteristics that only by strict control in the whole process of design,construction and operation can it meet the requirements of odor treatment of underground sewage treatment plants.
