The Investigation Of Environment Risk Source In Chemical Zone, Risk Assessment And Management Countermeasures

In recent years, environment and development become the focus of attention of theworld. With the rapid development of China’s chemical industry, chemical industry parkas a comprehensive park chemical production, processing, storage, transportation,processing as one of the dangerous substances, and potential energy is huge, to becomethe national economy the main point of growth at the same time, also embodies twoaspects of the development of the contradiction between economic development andenvironmental protection. Development of chemical industry park of environmental riskassessment and management countermeasure research, is an effective way to preventenvironmental risks, for the protection of people’s lives, health and property safety, it isof great significance to achieve a virtuous circle of sustainable economic and socialdevelopment and ecological environment.Construction of environmental risk assessment model using flammable, explosive,toxic and major risk sources evaluation method with the requirements andcharacteristics of environmental risk assessment. The specific evaluation process for thecomprehensive evaluation of substance on its own risk and technology risk by accidentproneness evaluation value, the fire and explosion, poison accident consequenceassessment value calculation of diffusion model, evaluation of environmental riskcounteraction factors from the emergency prevention facilities, early warningmonitoring facilities and comprehensive management level in three aspects, thecoupling calculation of environmental risk assessment value, then the analysis ofenvironmental risk rank.From the emergency prevention facilities, early warning monitoring facilities andenvironmental safety management of3factors,9indexes were selected to constructthe evaluation index system of risk counteraction factors, quantitativeassessment ofenvironmental risk prevention capacity to reduce environmental risk function.In the basis of environmental risk source investigation, use the above method toevaluate the Yangtze River Chemical Industrial Park environmental risk unit27. Results:4significant environmental risk source,8larger environmental risk source, and15general environmental risk source. Major environmental risk source as the focus ofdaily management of chemical industry park. Proposed the establishment of emergency organization system as the basis, totheenvironmental emergency plan for grasper, emergency warning system andemergencyresponse team construction of emergency rescue system as the focus of the proposal.
