摘　　要：目前我国在地下污水处理厂消防设计方面普遍存在较大困惑。通过火灾危险源识别,找出可能引发地下污水处理厂火灾的原因。建立火灾事故树,将地下污水处理厂火灾作为顶事件,从各基本事件的结构重要度排序可发现,可燃物与点火源接触、人员吸烟及违章动火、电力电缆及电气柜着火、电缆短路、车辆着火等对顶事件影响较大。针对可能引发火灾的不同原因,提出有效的管理措施及工程措施,可为地下污水处理厂在消防方面的设计及运行管理提供参考。At present,there are significant confusions in the fire protection design of underground sewage treatment plants in China.Through the identification of fire hazard,the possible causes of fire in the underground sewage treatment plant are found out.Establish a fire accident tree,and take the underground sewage treatment plant fire as the top event.From the structural importance ranking of each elementary event,it can be found that these points have a greater impact on the top event including the contact between combustible&ignition source,personnel smoking&illegal hot work,power cable&electrical cabinet fire,cable short circuit,vehicle fire,etc.Propose effective management&engineering measures for different possible causes of fires,which can provide reference for the design&operation management of underground sewage treatment plants in terms of fire protection.
