The results indicate that these six kinds of aquatic plants have high removal effects for ammonia-nitrogen and COD. Their removal effects of ammonia-nitrogen and COD reach a saturation state after treating for 5 to 7 days. Then, the removal effects do not increase significantly (P > 0.05) with extending the treatment time. The best removal efficiency for the ammonia-nitrogen in the coking wastewater by using Chara sp., Nasturium officinale, Cladophora sp., Potamogeton crispus, Polygonum orientale, and Phragmites australis is 20.38%, 19.37%, 23.61%, 22.59%, 21.77%, and 32.4%, respectively. The best removal efficiency for the COD in the coking wastewater by using Chara sp., Nasturium officinale, Cladophora sp., Potamogeton crispus, Polygonum orientale, and Phragmites australis is 27.51%, 27.13%, 18.63%, 17.03%, 25.72%, and 69.04%, respectively. Compared with the other 5 kinds of plants, Phragmites australis has the highest (P < 0.05) removal effect for ammonia-nitrogen and COD., authors=WANG Kai^1,2, LI Xia¹, CAI Jin¹, FENG Jia¹, XIE Shulian¹, authorsList=WANG Kai;LI Xia;CAI Jin;FENG Jia;XIE Shulian, authorCompany=1.

articleAbstract=为了研究水生植物对焦化废水的净化效果,本文运用重铬酸钾法和纳氏试剂分光光度法分析了轮藻、豆瓣菜、刚毛藻、菹草、红蓼、芦苇6种水生植物对焦化废水中氨氮、化学需氧量(COD)的去除作用。结果显示,6种水生植物对焦化废水中氨氮和COD均有较好的去除效果。6种水生植物处理焦化废水5—7d后,去除效果可达到平衡,继续延长处理时间,去除效果没有显著性变化(P > 0.05)。轮藻、豆瓣菜、刚毛藻、菹草、红蓼、芦苇对焦化废水中氨氮的最大去除率分别为20.38%、19.37%、23.61%、22.59%、21.77%、32.4%;对焦化废水中COD的最大去除率分别为27.51%、27.13%、18.63%、17.03%、25.72%、69.04%。其中芦苇对焦化废水中氨氮及COD的去除效果最好,且与其他植物有显著性差异(P < 0.05)。,
