含磷洗衣粉对太湖藻类生长繁殖的影响

The Effect of Phosphorus in Detergents on Algae Growth in Taihu Lake

以过滤后的太湖水样为基本试液,分别加入不同数量磷和含磷洗衣粉及太湖的优势种藻类,观察和测定各试样中藻类生长繁殖的变化. 结果显示,含磷洗衣粉对太湖微囊藻的生长有一定的促进作用,其中对含磷浓度较低湖水中藻类的影响尤为明显.

In laboratory, by using the water from Taihu Lake after filtrated as background experimental sample, and the experimental environmental condition simulate to the algae growth quickly status of Taihu Lake. In the background experimental sample the phosphates, detergent and dominance algae were used, then the algae growth for 12 days were surveyed. The algae growth results show that the phosphorus in detergents has a significant effect on algae growth in some degree. Especially, when the phosphate concentration less then 0.08mg/L, the phosphate in detergents are the main factor affecting the algae growth .
