摘要：随着工业的快速发展，生产中排放的含铜废水对水环境造成了很大的污染。本文通过研究不同浓度含铜废水对菖蒲光合特性的影响，探寻运用植物治理水污染的效果。实验环境模拟的是工业废水，在霍格兰氏营养液中加入不同浓度的硫酸铜，水培菖蒲。研究在不同浓度含铜废水（5mg/L、10mg/L）中，菖蒲生长情况、生理指标的变化情况。研究结果表明，含铜废水对水生环境中的菖蒲的光合作用影响显著，含铜废水（10mg/L）中的菖蒲的净光合速率明显比含铜废水（5mg/L）中的低。在铜离子浓度高的水环境中菖蒲生长势弱，在含铜离子浓度低的水环境中菖蒲生长势强。79844

Effects of different concentrations of copper containing wastewater on Photosynthetic Characteristics of Acorus calamus

Abstract: With the rapid development of industry, the production of copper waste water discharge in the water environment caused great pollution。 In this paper, by studying the different concentrations of wastewater containing copper calamus photosynthetic characteristics, the influence of exploring use plants governance effect of water pollution。  The experimental environment is simulated industrial waste- water, in the Hoagland's nutrient solution by adding different concentrations of copper sulfate。 The growth and physiological indexes of Acorus calamus (5mg/L, 10mg/L) were studied in different concentrations of copper(5mg/L, 10mg/L)。 The results showed that the copper containing wastewater had a significant effect on the photosynthesis of Acorus calamus in aquatic environment, and the net photosynthetic rate of Acorus calamus (10mg/L) was significantly lower than that of copper containing wastewater (5mg/L)。 In the water environment with high copper ion concentration, the growth potential of Acorus calamus is weak, and the growth potential of Acorus calamus is strong in the water environment with low concentration of copper ion。
