摘　　要：结合北京奥运会的重点工程——北京奥林匹克公园中心区龙形水系高效过滤、强化去磷系统工程;综合最新的过滤技术、吸附除氨氮技术、除磷技术、除藻技术和介质再生技术,研究开发了集成化的高效的水净化循环处理系统。研究结果表明龙形水系高效过滤、强化去磷系统微絮凝的最佳选择为PAC,最佳投药量为3.0 mg/L;沸石作为本系统吸附除氨氮的主要物质,其介质最好粒径范围:(1.0～2.0)mm,最佳无机改性剂为NaCl,且NaCl不会造成新的污染,每克沸石具有吸附18.0 mgNH3-N的极限潜力;本系统最佳的水藻抑制剂为澳大利亚的Alge Strave高浓缩水藻抑制剂,可以破坏水藻抑制剂,对鱼类未产生不良影响。A highly effective synthetic water purification system was exploited based on the core project, high effective filtration and reinforced phosphorus removal system for Dragon Style Water System in the centre of Olympic Park. It＇s researched that the best flocculant for the system is PAC and the most effective content is 3.0mg/L. The best particle diameter range of the main media, zeolite, for the filtration is （1.0-2.0） mm and the optimum inorganic modifier is NaCl. Every gram zeolite will absorb 18.0mg ammonia at most. The most effective depressor to algae of the system is Algae Strave produced by Waterco in Australia. It can destroy the cetaceous covering layer by feeding regularly and then the chlorinating agent will touch the cell of algae and kill it. It found that the depressor is harmless for the biology lives in the water under long term test.
