摘　　要：基于已构建的重点行业企业污染物排放强度评估模型,根据已掌握的天津市场地污染排放情况,选择了来自天津市五个重点行业(石化、农药、涂料、炼钢、电镀)的共25家代表性企业,对该模型进行了应用测试。通过评估方法对逐家企业进行优控污染物分析,随后构建评估指标体系并进行测算,将测算结果与实测结果进行对比,以验证排放强度评估模型在不同行业的适用性,进一步完善评估技术方法体系。测算结果表明,24家企业属于中强度排放,1家石化行业企业属于较高强度排放,测算结果与各企业风险筛查得分、优控污染物实测占标率的比对结果也具有整体一致性,个别企业存在出入,但情况基本吻合,总体在误差可接受范围内。本研究可为场地污染源排放强度评估测算提供参考,为经济快速发展地区场地土壤环境管理提供技术支撑。Based on the established pollutant emission intensity assessment model of enterprises in key industries,and according to the site pollution emission situation in Tianjin,a total of 25 representative enterprises from five key industries in Tianjin(petrochemical,pesticide,coating,steelmaking and electroplating)were selected to test the model.Through the evaluation method,the pollutant control was analyzed for each enterprise,and then the evaluation index system was constructed and calculated.The measurement results were compared with the measured results to verify the applicability of the emission intensity evaluation model in different industries and further improve the evaluation technology and method system.The results show that 24 enterprises belong to medium intensity emission,and one petrochemical industry enterprise belongs to high intensity emission.The calculated results also have the overall consistency with the comparison results of the risk screening scores of each enterprise and the measured proportion of optimal control pollutants.There are differences in individual enterprises,but the situation is basically consistent,and the overall error is within the acceptable range.This study can provide reference for the assessment and calculation of emission intensity of site pollution sources,and provide technical support for site soil environmental management in areas with rapid economic development.
