摘　　要：HAZOP法结合LOPA法可以为污泥薄层干化工艺提供更为丰富可靠的安全性分析。HAZOP法可以有效地发现和识别工艺中的潜在事故及危险源,LOPA可以定量化描述HAZOP的事故场景及现有保护措施,是HAZOP的延续和补充。采用两者相结合的分析结果表明:污泥薄层干化工艺对危险性较高的事故场景所采取的安全措施可有效地将事故风险降低至可接受的程度,该工艺是一套安全性很高的污泥处理工艺。HAZOP combined with LOPA can provide more abundant and reliable safety analysis for sludge thin film drying process.HAZOP can effectively find and identify potential accidents and hazards in the process.LOPA can quantitatively describe the accident scenarios and existing protection measures of HAZOP,which is the continuation and supplement of HAZOP.The results of the analysis using the combination of the two show that the safety measures taken by the sludge thin-layer drying process for the more dangerous accident scenarios can effectively reduce the accident risk to an acceptable level and that the process is a very safe sludge treatment process.
