doi:10.11894/iwt.2019-1126

Abstract

Abstract:

The purification effect and physiological response of six kinds of wetland plants on traditional Chinese medicine wastewater were studied. The results showed that the growth of wetland plants was significantly inhibited by traditional Chinese medicine wastewater. Among of them, the inhibition degree of pickerelweed was the least, while the antioxidant capacity was increase the highest. Wetland plants have obvious purification effects. Pickerelweed had the highest COD, NH₄⁺-N and chroma removal rate, and cyperaceae juss had the highest of BOD₅ and SS removal rate. The combination of pickerelweed-cyperaceae juss-reed-rush had the best purification effect on removal of COD, BOD₅, TN, NH₄⁺-N, SS and chroma were 82.36%, 80.65%, 85.38%, 86.69%, 96.33% and 80.49%, respectively.

摘要：

研究了6种湿地植物对中药废水的净化效果及生理响应。结果表明，制药废水显著抑制湿地植物生长，其中梭鱼草抑制程度最轻、抗氧化能力提升最高。湿地植物具有明显的净化作用，以梭鱼草对COD、NH₄⁺-N和色度去除率最高，而三棱水葱则对BOD₅和固体悬浮物去除率最高；梭鱼草-三棱水葱-芦苇-灯心草组合效果最佳，对COD、BOD₅、TN、NH₄⁺-N、固体悬浮物、色度去除率分别达到82.36%、80.65%、85.38%、86.69%、96.33%、80.49%。
