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。
Combined with the key project of the Beijing Olympic Games - the dragon-shaped water system in the central area of Olympic Park in Beijing, the dephosphorization system project is enhanced; the latest filtration technology, adsorption of ammonia removal technology, phosphorus removal technology, algae removal technology and medium regeneration technology are researched and developed The integrated and efficient water purification cycle processing system. The results showed that the best choice for micro-flocculation of dragon-shaped water system was PAC and the optimal dosage was 3.0 mg / L. Zeolite was the main material to adsorb ammonia-nitrogen in this system. The best particle size range : (1.0 ~ 2.0) mm, the best inorganic modifier is NaCl, and NaCl does not cause new pollution. It has the limit potential of adsorbing 18.0 mgNH3-N per gram of zeolite. The best algae inhibitor in this system is Australian Alge Strave High Concentrated Algae Inhibitor destroys algae inhibitors without adversely affecting fish.
