摘要传统地下污水处理厂以职业接触限值或污染物排放限值为设计标准,难以满足人员对健康和舒适的基本诉求。某地下净水厂基于更严格、更高标准的环境控制目标,采用了针对性的臭气密闭隔离和处理工艺,一体化整合通风、除臭系统,首次在南方地区将工艺设施操作层衔接下沉庭院等改进的技术措施与设计方法。实测结果表明,多处区域未检出硫化氢,臭气浓度低于20;与庭院衔接的区域自然风速稳定,污染物浓度为厂内最低水平;经处理后的尾气污染物排放值和厂界污染物浓度明显优于标准限值。项目实现了以人为本的环境质量效果,为建设舒适运维、和谐共生的地下污水处理厂提供了技术参考。 Traditional underground wastewater treatment plants are designed with occupational exposure limits or pollutant emission limits,which are difficult to meet the basic demands of personnel for health and comfort.Based on stricter and higher standards of environmental control objectives,an underground wastewater treatment plant(WWTP)adopted improved technical measures and design methods such as formulating targeted odor sealed isolation and treatment process,integrating ventilation and deodorization systems,and connecting the operation layer of process facilities to the sunken courtyard for the first time in the southern region.The results of measurements show that no hydrogen sulfide is detected and the odor concentration is below 20 in areas;The natural wind speed in the area connected to the courtyard is stable and the pollutant concentration is the lowest level in the WWTP;After deodorization,the emission values of exhaust pollutants and the concentrations of pollutants at the plant boundary are obviously better than the standard limit value.The project achieves the people-oriented environmental quality effect and provides a technical reference for building a comfortable operation and harmonious symbiotic underground WWTP.
