摘要:
[目的]针对淮南市焦岗湖近期污染物超标问题,开展本土4种水生植物进行水质净化试验,为焦岗湖利用水生植物修复水质提供可靠依据。[方法]在对淮南市焦岗湖水质检测的基础上,选取焦岗湖本土种植的泽泻(Alisma plantago-aquatica)、千屈菜(Lythrum salicaria)、石菖蒲(Acorus tatarinowii)以及金鱼藻(Ceratophyllum demersum)等水生植物为研究对象,在人工模拟自然条件下,研究其对焦岗湖水体中总氮(TN)、总磷(TP)、氨氮(NH3-N)、化学需氧量(COD)等污染物的去除效果。[结果]千屈菜、泽泻和石菖蒲对TN去除率较好;石菖蒲和金鱼藻对氨氮去除效果良好,千屈菜对TP去除效果最佳,而对于COD而言,4种水生植物均有较为理想的去除效果。[结论]所选取的4种水生植物对各污染物均有一定的去除效果,将水生植物的种植面积、数量和时间进行优化配置,可用于焦岗湖水质改良。

Abstract:
[Objective] To solve the problem of excessive pollutants in Jiaogang Lake in Huainan City, four native aquatic plants were tested for water purification. The experiment was expected to provide a reliable basis for the use of aquatic plants to repair water quality in Jiaogang Lake.[Methods] Based on the water quality test data of Jiaogang Lake in Huainan City, Alisma plantago-aquatica, Lythrum salicaria, Acorus tatarinowii and Ceratophyllum demersum grown locally in Jiaogang Lake were selected as research objects, the removal effects of aquatic plants on TN, TP, NH3-N and COD in water body of Jiaogang Lake were studied under simulated natural-alike conditions.[Results] The removal rate of TN was better in Lythrum salicaria, Alisma plantago-aquatica and Acorus tatarinowii. The removal rate of NH3-N was better for Acorus tatarinowii and Ceratophyllum demersum. Lythrum salicaria had the best effect on removing TP, while for COD, the four aquatic plants had better removal effect.[Conclusion] The four selected aquatic plants have certain removal effects on pollutants. The optimum arrangement of planting area, quantity and time of aquatic plants can be used for water quality improvement of Jiaogang Lake.
