摘　　要：城市化发展与恶臭污染的矛盾日益严峻,当前控制技术受限于填埋场恶臭组分复杂、季节变化因素多、变化规律难界定和露天作业封闭难等问题,防治效果不佳。基于CFD仿真模拟技术,采用二氧化氯喷雾氧化除臭技术,通过CFD仿真模拟风场,确认恶臭污染物的空间分布特征;根据模拟结果选取重点二氧化氯喷雾范围,布置风炮封锁臭气,并提出相应防治措施。各设备确保实时监控,以达到智能化控制恶臭的目的。The contradiction between urbanization and odor pollution is becoming more and more serious.At present,the control technology is limited by the problems of complex odor components in landfills,many seasonal variation factors,difficult to define the changing rules and difficult to close open-air operations,which leads to bad control effect.Based on CFD simulation technology,chlorine dioxide spray oxidation deodorization technology was adopted.The spatial distribution characteristics of odor pollutants were confirmed through CFD simulation of wind field.According to the simulation results,the key spray range was selected.The wind gun was arranged to block off odor and the corresponding prevention and control measures were put forward.The equipment could be monitored in real time to control odor intelligently.
