云龙湖水环境现状评价及其生态修复研究

Study on the Evaluation of Water Environment Actuality and Ecological Restoration of Yunlong Lake

针对徐州市云龙湖水环境质量10年前后的变化,分析了云龙湖水量平衡状况、水体的功能和水环境质量提高的主要因素及目前仍存在的高锰酸盐指数、生化需氧量、氨态氮、总磷、总氮、粪大肠菌群超标等问题,并提出采用设立环湖绿色保护带、建立生态处理工程、建立污泥处理工程、建立环湖污水截流系统、优化云龙湖给水系统、增大云龙湖水环境容量、控制云龙湖主水体的生物量平衡、加快生态农业建设、建立南湖生态养殖区、多渠道筹集环保资金和依法监管、加强宣传、综合治理等生态修复整改措施。

Aiming at the changes of the water environment quality of Yunlong Lake in Xuzhou City before and after 10 years, the main factors of enhancing the water balance situations, the functions of water body and water environment quality of Yunlong Lake and existing problems such as the exceeding standard of permanganate index, biochemical oxygen demand, ammonia nitrogen, total phosphorus, total nitrogen, fecal coliform were analyzed. Some ecolngical restoration measures were put forward, including establishing the green protective belt around Yunlong Lake, setting up the ecological processing engineering, establishiog the sludge processing engineering, setting up the sewage interception system around Yunlong Lake, optimizing the water supply system of Yunlong Lake, increasing the water environment capacity of Yunlong Lake, controlling the biomass balance of main water body of Yunlong Lake, speeding up the construction of ecological agriculture, establishing the ecological culture area of South Lake, supervising according to the law and strengthening the propaganda and comprehensive management.
