| 摘 要： | 选取滇池福保湾表层沉积物,以聚合氯化铝为钝化剂,研究了扰动强度对钝化剂抑制沉积物中磷释放的影响.结果表明,当扰动强度低于一定范围时,聚合氯化铝对沉积物中的磷有抑制作用,当转速为0,60,120r/min时,对应的水中磷浓度分别为初始值的62.5%,71.7%和83.4%;当转速达到240r/min时,沉积物会向水中释放大量磷,钝化作用完全被破坏,水中磷浓度为初始值的3.3倍.此外,在转速低于120r/min时,磷形态主要是以无机磷(DIP)为主的溶解性磷(DTP),而转速达到240r/min时,水中DTP/TP30%,DIP/DTP40%,即磷形态主要为不溶性磷,溶解性磷中以有机磷(DOP)为主. |

| Abstract: | To make sure if the inactivation agent on the phosphorus(P) release inhibition can last for long time,the sediments from Fubao Gulf of Lake Dianchi were selected,for the experiment to study the effect of perturbance strength on the P release inactivation capability of the inactivation agent(PAC).When the speed of the stirrer was in a certain range,the inhibition of PAC on P release from the sediment was obvious.when the speeds of the stirrer were at 0r/min,60r/min and 120r/min the amounts of P in the water ... |
