| 摘 要： | 通过植物的采集、培育和选种,获得了海芋、合果芋、蜘蛛兰和密穗砖子苗等4种同时具备去碳、脱氮、除磷和积累重金属的高效修复植物,并对这些植物修复污染水体的性能进行了研究。结果表明,这4种植物均能有效地处理有机物和重金属复合污染水体。鲜重55-60g的植物,处理10L BOD5、CODCr、TP、TN、Cu2+和Cr6+浓度分别为140、280、6,8、40、10和10 mg·L-1的模拟水样14d后,上述指标的去除率分别高达80%、72%、64%、53%、75%和68%以上,植物的促进作用分别为32%、27%、27%、28%、37%和19%以上。处理后水样的pH和DO分别为6.63～7.63和3.02～3.84 mg·L-1。 |
