- 摘要：多花黑麦草(Lolium multiflorum)是我国从意大利引进的优质鱼类陆生饲草(以下简称黑麦草), 为宿根性禾本科草本植物.其特性为生长快, 繁殖力强, 较耐寒.利用黑麦草来净化缫丝和啤酒等有机废水已有报道[1—3], 但对黄金废水的净化、吸收与富集作用, 至今尚未见有报.为了能有效地净化黄金废水和从废水中提取黄金, 本文作了静态模拟研究.
- Abstract：The purification and accumulation of gold in gold bearing wastewater with Lolium multiflorum were studied.In the static experiment, the wastewater volume was 15 liters, plant weight was 0.2kg, and original concentrations of gold were 0.5mg/L, 1.0mg/L and 2.0mg/l, respectively.After 5 day detention, purification rates of gold were 99.70%, 99.35% and 99.54% accordingly.The accumlation amounts of gold in root ash were 223.9g/t, 2144.3g/t and 3097.6g/t, respectively.Therefore, this study offered definite scientific foundations for purifying gold bearing wastewater.
