高效生物强化技术的应用研究--以广西九洲江支流某河段异位治理为例

广西九洲江流域水污染不仅仅是生态环境问题,还是关乎玉林地区社会稳定、百姓脱贫致富、下游广东湛江群众饮用水安全的经济社会问题。以九洲江支流某河段水环境污染治理为模板,概述了人口稠密、畜禽养殖量大的地区水污染形成的原因和机理,并结合当地的污染特点,采用高效生物强化技术异位治理九洲江支流某河段水体污染。经该技术处理后,出水可稳定达到Ⅳ类以上水质标准,达到水域功能区划水质标准和水质断面考核目标要求,为水环境治理及生态修复提供理论基础和实践支撑,对研究我国不同地区水污染治理具有重要的理论和现实意义。

Water pollution in the Jiuzhou River basin is not only an ecological and environmental problem,but also an economic and social problem related to the social stability in Yulin,the People's poverty alleviation and the drinking water safety of the people in Zhanjiang.Taking the treatment of water environment pollution in a branch of Jiuzhou River as a template,this paper summarizes the causes and mechanisms of water pollution in densely populated areas with large livestock and poultry production,and combines with the local pollution characteristics,the water pollution in a branch of the Jiuzhou River was treated by high-efficiency bioaugmentation technology.After this technology treatment,the effluent could reach the water quality standard of Grade IV or above,meeting the requirements of water quality standards for water area functional zoning and assessment of water quality monitoring sections,and providing theoretical basis and practical support for water environment treatment and ecological restoration,it has important theoretical and practical significance for the study of water pollution control in different areas of China.
