摘要
威立雅除臭通风采暖一体化集成系统经多年的发展和在世界多个国家及地区的应用,实际运行均达到了理想的臭气排放标准,保证了厂区良好的通风环境,最大限度地降低了对周边环境及居民的臭气污染。介绍了核心的臭气收集系统设计经验,将地埋厂区空间的通风系统和臭气收集系统整合设计,并通过合理设计换气率、空间除臭、微污染气体的转移等一系列风量平衡措施合理地设计通风和除臭,尽可能地降低总投资成本和运行成本。该系统成功应用于北京槐房再生水厂地下厂区,项目最终排放指标达到北京排水集团企业标准并优于北京市地方标准《大气污染物综合排放标准》(DB 11/501—2007)。
Veolia's deodorization and HVAC integration system has been developed for many years and applied in many countries and regions around the world. The actual operation performance reached the ideal odour emission standards,so that good ventilation environment of the plant could be ensured,and the odour pollution to surrounding environment and residents was reduced to the maximum extent. The paper introduced the key point of design experience of odour collection system. The ventilation and deodorization parts were designed as an integrated system. A series of air volume balance measurements as reasonable air renewal rate,space deodorization,and diluted odour transferring were designed to reduce the total investment and operation costs as far as possible. The integrated system was applied in Beijing Huaifang recycle water treatment plant. The discharge indexes of the plant achieved the emission standard Beijing Drainage Group specifies,and better than Beijing local standard Integrated Emission Standards of Air Pollutants( DB 11/501-2007).
