Abstract

Abstract

This study systematically reviewed the policies， regulations， and standards governing industrial wastewater reuse in China， and identified the institutional challenges in policy implementation. Through a case study of reclaimed water utilization at a semiconductor manufacturer in Jiangsu Province， the research explored feasible approaches for water reuse in the electronics industry via integrated policy and water quality analysis. Key findings include： 1） The existing regulatory framework remains incomplete， with regulatory conflicts between end-of-pipe pollution control requirements and reuse demands， and the lack of scenario-specific standards and specifications constitutes a major constraint on development； 2） The reclaimed water produced by the semiconductor manufacturer through the dual-membrane （ultrafiltration-reverse osmosis） treatment process is significantly superior to the limit values specified in the Chinese National Standards GB/T 19923—2024， GB/T 18921—2019， and GB/T 25499—2010， and outperforms the water quality of surrounding natural water bodies and can meet the process water demands of most enterprises in the industrial park. Given the established technical feasibility of water quality compliance， the core challenge for this semiconductor manufacturer's wastewater reuse lies in resolving the regulatory constraints on the application of reclaimed water for industrial and scenic environmental purposes.
