摘　　要：化学工业是推动制造强国战略实施的重要支撑,化工园区是新型工业化的关键载体,开展化工园区减污降碳技术应用研究具有重要的现实意义。本文针对化工园区减污降碳面临的资源利用率低、减污和降碳协同性差、末端治污成本高、环境安全与风险突出等挑战,分析了化工园区碳和污染物产生的特点并梳理相关研究进展,剖析了减污降碳协同增效的内涵。在此基础上,建立了基于一般性工业过程的分析框架,以物质、能量代谢过程为纽带,从企业生产、基础设施、产业共生等层面演绎提出了化工园区减污降碳的技术路径:建立化工园区内企业的碳、污染物排放清单;集成优化化工园区的技术与产业结构,加强绿色低碳生产技术开发、基础设施升级共生、企业间合作、减污降碳与安全生产统筹、产品‒产业‒空间结构优化;开展全生命周期减污降碳成本效益评估。选取杭州湾上虞经济技术开发区为典型案例,总结了化工园区减污降碳技术路径的应用实践,进而提出了化工园区减污降碳实施路径建议:完善精细计量体系,加强化工园区物质流管理;强化化工园区共生链接,运用系统工程赋能减污降碳;激发系统效率变革,推动化工园区绿色高质量发展。The chemical industry plays a crucial role in strengthening the manufacturing sector of China,and chemical industrial parks are key platforms for new industrialization.Chemical industrial parks encounter numerous challenges in mitigating pollution and carbon emissions,encompassing issues such as a low resource-utilization rate,deficient recycling practices,substantial costs associated with end-of-pipe pollution control,and escalated safety and environmental risks.This study investigates collaborative pathways for pollution reduction and carbon mitigation within chemical industrial parks.According to the characteristics and research progress of carbon emissions and pollution generation,the implications of carbon reduction synergies are analyzed.A comprehensive analytical framework is established for general industrial processes,covering material metabolic processes in enterprise production,symbiotic metabolism in industrial parks,and material metabolism in park infrastructure.Moreover,specific technical pathways for pollution reduction and carbon mitigation are proposed:(1)establishing a comprehensive inventory of carbon and pollutant emissions;(2)integrating and optimizing the technological and industrial structures of chemical industrial parks through the development of green production technologies,symbiotic upgrades in infrastructure,enhanced inter-enterprise cooperation,coordinated efforts in pollution reduction,carbon mitigation,and safety production,and optimization of product-industry-space structures;and(3)conducting a cost-benefit analysis of pollution reduction and carbon mitigation technology pathways through a life cycle assessment.Employing the Hangzhou Bay Shangyu Economic and Technological Development Zone as a case study,an empirical analysis of pollution reduction and carbon mitigation technology pathways is undertaken.Furthermore,recommendations are made from three perspectives:improving precision measurement systems to strengthen material flow management in chemical industrial parks,reinforcing
