Study and application of highly effective filtration technology in Dragon Style Water System of the Olympic Park

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 ceraceous 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.
