【摘要】 针对印染生化尾水中残留色度及营养盐去除难的问题,提出了人工光源强化沉水植物深度净化的新方法。实验结果表明,人工光源补光条件下,金鱼藻和苦草对印染生化尾水中色度、TP和NH₄⁺-N的去除效果均优于无补光组。其中,采用红光辅助金鱼藻的净化处理效果最好,当停留时间为5 d时,可将印染生化尾水中的色度从40倍降至8倍左右,TP从1.50 mg/L降为0.11 mg/L,NH₄⁺-N从8.00 mg/L降为1.83 mg/L,色度、TP、NH4₊^-N去除率分别达到80.0%、92.6%和77.1%,处理出水达到地表水环境V类水标准（GB 3838—2002）。更多还原

【Abstract】 Aiming at the problem that the removal of residual chroma and nutrient salt from biochemical dye tail water is difficult,an advanced purification method of artificial light enhanced submerged plants has been proposed. Experimental results show that under artificial light supplementary lighting condition,the effects of ceratophyllum demersum and vallisne on the removal of chroma,TP and NH₄⁺-N from biochemical dye tail water are all better than that of the group without supplementary lighting. Among them,the treatment effect of using red light for assisting the purification of ceratophyihum is the best. When the detention time is 5 days,the chroma in biochemical dye tail water can be decreased from about 40 times to 8 times,TP can be decreased from 1.50 mg/L to 0.11 mg/L,and NH₄⁺-N decreases from 8.00 mg/L to l.83 mg/L,the removing rates of chroma,TP and NH₄⁺-N can reach 80.0%,92.6%,and 77.1%,respectively. The treated effluent reaches level V water standard of surface water environment（GB 3838—2002）.更多还原
