摘　　要：以城市污水厂格栅间为研究对象,在分析恶臭气体产生特性的基础上,研发出新型双介质气动雾化喷淋系统,并对系统运行参数进行了优化。将该系统应用于北京市某城市污水厂格栅间,考察了其对硫化氢和氨的去除效果。结果表明,该系统对污水厂格栅间的硫化氢和氨的去除率分别为90.54%~97.80%和93.75%~99.42%,取得了较好的除臭效果。该系统投资费用为95万元,运行费用为3.62万元/a,其中水费占运行费用的51.10%。新型双介质气动雾化喷淋系统较好适用于城市污水厂分散点源恶臭气体的原位处理。Taking the screen room in municipal sewage treatment plants(MSTPs)as the object,a new-type double medium pneumatic atomization spray system was developed based on the characterisctics of odour from scattered sources in MSTPs,and the operating parameters of the system were optimized.The system was applied in a MSTP in Beijing and its performence was studied.The results showed that the removal efficiency of hydrogen sulfide and ammonia in the screen room were 90.54%-97.80%and 93.75%-99.42%,respectively with a good deodorization effect.The investment cost of the system was 950000 yuan,and the operating cost was 36200 yuan/a.The water cost accounted for 51.10%of the operating cost.The new-type double medium pneumatic atomization spray system is suitable for the in-situ treatment of odour from scattered sources in MSTPs.
