Core Viewpoint - The compilation of the Ecological Environment Code marks a milestone in China's ecological civilization legal construction, providing a comprehensive legal framework for water pollution prevention and control [3][10]. Group 1: Water Pollution Prevention - The specialized section on "Water Pollution Prevention" in the Code outlines clear regulations for key areas such as industry, urban areas, agriculture, and shipping, aiming to protect water quality [3][5]. - The core value of seawater desalination technology is to provide additional water resources for coastal areas facing water scarcity, while also offering advanced separation technologies applicable to various pollution control challenges [5][10]. Group 2: Industrial Wastewater Treatment - Technologies developed for zero discharge of industrial wastewater have been successfully implemented in projects like the distillation wastewater treatment in Fujian, achieving zero discharge and reuse of saline wastewater [5][6]. - The treatment technology for high-salinity heavy metal wastewater in Henan demonstrates effective recovery of precious metals and supports the Code's requirements for heavy metal pollution prevention and resource recovery [5][6]. Group 3: Agricultural and Rural Pollution Control - Innovative ecological solutions for treating aquaculture wastewater have been developed, utilizing microbial purification and multi-level nutrient coordination to meet the Code's requirements for agricultural non-point source pollution control [7][9]. - Successful applications of these technologies have been reported in various regions, significantly improving wastewater discharge standards [7][9]. Group 4: Technological Innovations - The development of comprehensive water ecological governance technologies integrates various agents and methods to effectively address issues like eutrophication and black-odor water bodies [9][10]. - The emphasis on technological innovation is crucial for the implementation of the Code, with a focus on transforming technical advantages into dual benefits of increased water resources and reduced pollution [10].
