城镇地下污水处理厂环境控制策略与设计标准简析
Brief analysis on environmental control strategies and design standards for urban underground sewage treatment plants
摘要：
针对地下污水处理厂除臭系统和通风系统在传统设计中未能统筹考虑而导致空气环境失控的问题，通过简要分析地下污水处理厂地下空间空气环境特性、污染物排放标准、污染物初始浓度标准及臭气治理的重点和难点，结合多个地下污水处理厂工程实践经验，提出了地下污水处理厂通风与除臭系统相结合的环境控制策略及设计标准。
Abstract：
In view of the problem that the air environment is often out of control because the deodorization system and ventilation system of underground sewage treatment plants are not considered as a whole in the traditional design, this paper analyses the underground space air environment characteristics, pollutant discharge standards, initial concentration standards of pollutants and key points and difficulties of odor treatment, combined with the practical experience of several underground sewage treatment plants. The environmental control strategy and design standard of the combination of ventilation and deodorization system in underground sewage treatment plants are put forward.
