The Environmental Risk Assessment And Management Of A Petrochemical Project Construction In Daya Bay

With the rapid development of China’s chemical industry,the coastal chemical park has gradually become a comprehensive park integrating production,processing,transportation,storage and disposing.Although the integrated model increases productivity,the park also integrates multiple sources of flammable,explosive or toxic hazards,making the difficulty of environmental risk management significantly greater.In order to improve the level of environmental risk management,this paper comprehensively screens out the risk assessment methods suitable for Daya Bay area according to the requirements and characteristics of environmental risk assessment,and takes A petrochemical project as an example.Firstly,the status quo of air,groundwater,soil,marine life and acoustic environment around Project A is investigated and analyzed as a reference standard for subsequent risk assessment.Secondly,using the major hazard assessment method,analytic hierarchy process and LEC evaluation method as the basic evaluation method to evaluate the environmental risks brought about by the construction and operation of the A project;finally,simulation predicts the environmental impact of the leakage of harmful poisons.The evaluation results show that the wastewater generated by Project A has the greatest risk of soil pollution,not only the most serious pollution hazard,but also the highest probability of occurrence,which should be included in the primary risk management object.In addition,the environmental risk ranking of multiple projects can be obtained by using the evaluation method constructed in this study.The ranking results can provide reference for the park managers to determine the landing project.
