摘要
藻类生长需要适当的光强,水体中悬浮物(如泥沙)的存在,势必对进入水体的光强产生抑制,从而影响藻类生长。通过实验研究了不同浓度和不同粒径的泥沙对藻类生长的影响,结果表明,适量的泥沙浓度反而使水体chla最大浓度比空白水体有所增大,100目粒径的泥沙对光线的阻隔作用最强。
It has been known that algae need some sun light for their growth. Because there are lots of sand particles in aquatic system subjected pollution, they must restrain the light intensity in water, therefore, they will affect the growth of algae. The present experiments were brought from the different concentrations and particle sizes of the sand, in order to study the effects. It suggested that the concentration of the algae under proper concentration of sand be larger than that without sand, and the particle size of 100 was the highest to restrain the sun light.
