Research on collaborative governance of marine aquaculture wastewater discharge water purification and ecological protection
海水养殖尾水排放水质净化与生态保护协同治理研究

摘要

海水养殖对于保障水产品供应、推动沿海地区经济发展而言有着重要意义。然而要是高密度养殖所产生的尾水未能得到充分处理，便极易引发近岸水体出现富营养化情况，致使底质恶化，进而造成生态系统退化。海水养殖尾水治理不应仅仅局限于末端实现达标排放这一层次，还应当和养殖模式的优化、污染源的削减、海域生态的保护相互结合。本篇文章针对海水养殖尾水污染特点、水质净化技术、生态保护协同途径展开剖析，提出把源头减排、过程调控、尾水净化、生态修复相互结合的治理想法，期望可以为海水养殖绿色转型给予参考。

Abstract

Marine aquaculture plays a vital role in ensuring the supply of aquatic products and promoting economic development in coastal areas. However, if the wastewater generated by high-density aquaculture is not adequately treated, it can easily lead to eutrophication of nearshore waters, resulting in sediment deterioration and ultimately ecosystem degradation. Wastewater treatment in marine aquaculture should not be limited to achieving standard discharge at the end of the process; it should also be combined with the optimization of aquaculture models, the reduction of pollution sources, and the protection of marine ecosystems. This article analyzes the characteristics of marine aquaculture wastewater pollution, water purification technologies, and collaborative approaches to ecological protection. It proposes a governance approach that combines source reduction, process control, wastewater purification, and ecological restoration, hoping to provide a reference for the green transformation of marine aquaculture.
