沸石去除铜绿微囊藻的试验研究

用粒径0．28mm以下的沸石粉处理实验室培养、处于稳定期的铜绿微囊藻水样，结果表明：沸石粉颗粒通过吸附一沉淀作用，使铜绿微囊藻细胞及其群体产生沉降，且沉降性能稳定，并可以有效地去除水中的氨氮和活性磷，特别是对活性磷吸附牢固；沸石粉效果的显著性与其投加量有关，投加量越高，效果越显著；藻类自身特性对沸石粉的沉降效果有显著影响。

Removing of Microcystis aeruginosa by use of zeolite powder

Using zeolite powder (diameter below 0.28 mm) as a treating agent, this paper had studied the removing effects of Microcystis aeruginosa cultured in laboratory and growing in stable period. The results show that zeolite powder had achieved better treatment effects on Microcystis aeruginosa by mechanisms of adsorption and co-settling with the alga cells and their colonies but given different efficiencies between the other two algae co-growing in the sample, which indicate the influences of characteristics of each alga. At the same time, ammonia-nitrogen and active phosphorus in samples have also been effectively removed, especially the active phosphorus were adsorbed firmly and stably that might be used as a way to control Microcystis aeruginosa in water body.The increase of amount of zeolite powder results in better treatment effects.
