RESEARCH ON WATER NETWORK OPTIMIZATION OF HIGH-TECH INDUSTRIAL PARKS FACING LOW-CARBON CONSTRAINTS
Exploring the green development model for high-tech industrial parks is crucial to leading the transformation of high-tech industries over China.Low-carbon and near-zero sewage emissions are an effective measure to promote the transformation of the energy structure of high-tech industrial parks under the new situation of carbon peak and carbon neutrality.However,the current research milieu predominantly concentrates on enhancing the efficacy of wastewater treatment and recycling technologies at the local unit level,often overlooking the integrated management of water recycling and carbon emission dynamics across various water-related subsystems at the park-wide scale.This oversight hinders the holistic implementation of low-carbon,near-zero emission practices within the park,thereby impeding the development of a truly sustainable,low-carbon park environment.In light of these challenges,the present study adopts a high-tech industrial parks as its focal point,systematically scrutinizes the water usage patterns,effluent characteristics,and carbon footprint of representative industries within the park,and endeavors to optimize the water network within the industrial park under the constraints of low-carbon objectives.Furthermore,it introduces an innovative model for achieving low-carbon,near-zero emission sewage management in the park.This model,termed"five-level treatment-five-level carbon reduction,"is tailored to the existing industrial and hydrological profiles.It adeptly integrates and leverages a spectrum of strategies including"Differentiated utilization-source carbon reduction,Resource recovery-enhanced carbon reduction,Energy conservation and emission reduction-energy regeneration,Deep purification-ecological reuse,Recycling-comprehensive carbon control".This multifaceted approach aims to provide a viable and actionable roadmap for the green and sustainable evolution of high-tech industrial parks,aligning with the broader goal of environmental stewardship and carbon neutrality.
