| 摘 要： | 建立了一套包含有城市河涌底泥、覆盖材料及上覆水的小试装置,采用粉煤灰、水泥、沸石、河砂、玻璃珠等不同物质作为覆盖材料,在厌氧条件下,覆盖材料对城市河涌底泥磷释放的控制效果进行了研究.结果表明,在培养温度为25℃,覆盖材料用量为6.0kg·m-2时,玻璃珠、河砂、沸石、粉煤灰、水泥对PO43-释放的抑制率分别为40.0%、46.7%、60.0%、75.6%、88 9%;覆盖材料对PO43-的抑制作用可归结为覆盖材料的覆盖效应、化学效应和吸附效应;覆盖材料对PO43-释放的抑制率均随着温度的升高而降低;覆盖材料用量对PO43-抑制率影响较大,对于水泥、粉煤灰、沸石、河砂,要达到约50%的PO43-释放抑制率,其用量分别为2.0、2.0、6.0、10.0 kg·m-2,选用粉煤灰作为覆盖材料较合适;从重金属毒理学方面讲,覆盖材料不会对底泥及区域土壤造成影响.
