, 2012 本发明公开了一种光催化还原和沉水植物联合处理沉积物磷的方法,其步骤是：1)筛选出当地气候及水域条件的沉水植物；2)将沉水植物种植到装有沉积物的玻璃器皿中,在沉积物上铺一层负载纳米半导体光催化剂薄膜的新型环保滤球；3)注入上覆水,其上覆水采自沉积物采样点上的水柱；4)在沉水植物生长初期和衰退期通过外加光源进行间歇照射,外加光源既能使光催化剂进行光催化反应,又能满足沉水植物生长所需光照；5)每隔一段时间采集沉积物样品,测定沉积物各形态磷变化情况。方法易行,操作简便,能高效去除富营养化水体沉积物磷,

, 2019 该文阐述了沉水植物对湖泊沉积物N、P负荷控制的机理,并统计了相关研究中沉水植物对内源负荷的控制效果。沉水植物可以通过生长繁殖吸收、促进微生物代谢分解、改善沉积物理化环境、抑制沉积物再悬浮等多种途径降低沉积物中N、P含量或抑制N、P释放通量,从而有效控制水体内源负荷。根据相关模拟研究及野外研究得出沉水植物对沉积物中N、P的年平均去除量分别为1 136和387 mg·kg~(-1)·a~(-1),且与沉积物的污染物中初始浓度呈正相关关系;与对照相比,沉水植物对水-沉积物界面N ...
