大型城市污水处理厂安全评价

安全检查人苏倩中原环保港区水务分公司安全评价TheSafetyAssessment摘要本文简要介绍了港区水务的现状，包括城市污水处理厂的生产指标、平面布置、处理工艺以及主要生产设备等。主要工作是对污水处理厂的安全评价，目的是查找、分析和预测系统存在的危险、有害因素与可能导致的危险、危害事故后果和程度，提出合理可行的安全对策措施，指导危险源监控和事故预防，以达到最低事故率、最小损失和最优的安全投资效益。文中对污水处理厂的主要危险有害因素进行了辨识分析。在评价过程中将污水处理厂分为污水处理系统、变配电系统和沼气收集利用系统三个评价单元，分别用安全检查表法和系统火灾爆炸指数评价法对其进行了评价。评价过程中指出了此污水处理厂存在的安全问题并给出了整改措施和建议。最后给出了安全评价的结论。关键词：污水处理厂有害因素危险源安全评价安全检查表法系统火灾爆炸指数评价法AbstractThispaperbriefintroducesthesewagetreatmentplanteastzonestatus,includingurbanwastewatertreatmentplantproductionindex,layout,processingtechnology,andmajorproductionequipment,etc.Maintaskistoevaluatethesafetyofthesewagetreatmentplant,thepurposeistofind,analyzeandforecastsystempresentdanger,harmfulfactorsandmaycausedanger,harmaccidentconsequencesanddegree,andputsforwardthereasonableandfeasiblesafetycountermeasures,guidinghazardsmonitoringandaccidentprevention,inordertoachievetheminimumrate,minimumlossandoptimalofsafetyinvestmentbenefits.Inthispaper,themajorriskandharmfulfactorsofsewagetreatmentplanthasbeenrecognizedandanalysis.Thesewagetreatmentplantwillbedividedintosewagetreatmentsystem,powerdistributionsystemsandbiogascollectionandutilizationsystemofthreeevaluationunitsintheevaluationprocess,andrespectivelyevaluatedbySafetyCheckListandDowFire&ExplosionIndex.EvaluationprocesspointsouttheexistingsafetyproblemsofthesewagetreatmentplantandgivetheimprovementmeasuresandSuggestions.Finallygivesasafetyassessmentconclusion.Keywords:sewagetreatmentplant;harmfulfactors;hazard;safetyassessment;safetychecklist;dowfire&explosionindex.目录第1章绪论.......................................................................................................................11.1研究背景...................................................................................................................11.2国外研究现状...........................................................................................................11.3国内研究状况...........................................................................................................21.4主要工作及研究方法...............................................................................................31.4.1主要工作............................................................................................................31.4.2研究方法............................................................................................................31.5预期结果...................................................................................................................3第2章港区水务概况.......................................................................................................52.1污水处理厂的基本情况...........................................................................................52.2污水处理厂厂区总体规划及总平面布置...............................................................52.3污水处理厂的主要处理工艺...................................................................................62.4污水处理厂的主要生产设备...................................................................................72.5本污水处理厂的特点...............................................................................................7第3章主要危险、有害因素辨识与分析.......................................................................83.1危险、有害因素的定义...........................................................................................83.2危险因素辨识和分析...............................................................................................83.2.1火灾爆炸危险....................................................................................................83.2.2触电伤害危险..................................................................................................103.2.3高处坠落危险..................................................................................................113.2.4淹溺伤害危险..................................................................................................113.2.5起重伤害危险..................................................................................................123.2.6机械伤害危险..................................................................................................123.2.7高温烫伤危险..................................................................................................123.2.8灼伤危险..........................................................................................................133.3有害因素辨识和分析.............................................................................................133.3.1中毒、窒息......................................................................................................133.3.2噪声危害..........................................................................................................143.3.3高温危害..........................................................................................................143.4生产场所的主要危险、有害因素.........................................................................14第4章安全评价.............................................................................................................154.1评价目的及原则............................................
