水葫芦的资源化利用研究

针对目前水葫芦〔Eichhornia crassipes(Martius)Solms-Laubach〕疯长带来的污染大、难处理的问题,进行了水葫芦污水净化及日光玻璃温室干燥试验。结果表明,种植了水葫芦的食堂污水氮磷含量在较短时间内明显下降,去除率分别可达94.3%和94.2%,水葫芦吸收带走的氮、磷量(试验水葫芦中增加的氮、磷量)分别为490.2、130.5 mg/kg;此外,定时鼓风的玻璃温室的干燥速率比自然晒干快,若将水葫芦干燥至含水率为10%左右,温室干燥需要6 d,而自然晒干需要9 d。

Comprehensive utilization of water hyacinth

In the consideration of current huge pollution caused by water hyacinth,which is intractable,the experiments of water hyacinth sewage treatment solar glass greenhouse drying and water hyacinth fertilize making were done.The results showed that the nitrogen and phosphorus contents of the refectory sewage decreased in a relatively short period of time,and the reduction rates were 94.3% and 94.2% respectively,the water hyacinth absorption of nitrogen and phosphorus reached 490.2 mg/kg and 130.5 mg/kg;The resul...
