摘要：

在前期工作中我们发现，水葫芦叶柄切片经养猪场沼液浸泡后，其总磷含量增加一倍。为了探讨水葫芦叶柄切片总磷含量增加的原因，我们就水葫芦叶柄切片对可溶性磷和不可溶性磷及悬浮物的吸附作用进行了研究。结果显示:水葫芦叶柄切片对水体中的可溶性磷没有吸附作用；在本实验条件下，未能吸附磷酸钙固体颗粒；能从沼液池中吸附相当于自身重量60%的悬浮物；该悬浮物总磷含量为0.71%。因此，我们推断，水葫芦叶柄切片经沼液浸泡后总磷含量增加的主要原因是由于其从沼液中吸附了大量的悬浮物。

Abstract:

According to our earlier work, the total phosphorus concentration in the biogas fluid-soaked water hyacinth stalks doubled. To explain why the total phosphorus concentration increased, experiments on phosphorus and suspended solids adsorption by water hyacinth stalks were performed. The results of the present study indicated that soluble phosphorus was not adsorbed by the water hyacinth stalks, neither was Ca3(PO4)2. The experimental results also showed that per 100g the stalks adsorbed about 60g suspended solids which contained 0.71% total phosphorus. So it was concluded that the increase of total phosphorus in the biogas fluid-soaked water hyacinth stalks was mainly induced by suspended solids adsorption.
