摘要
利用富营养化水体营养盐资源，使用泡沫板、蛭石两种人工基质无土栽培水芹、水蕹菜和多花黑麦草，研究其净化污水的效果。室内试验结果，３种植物的生长状况良好。其叶长、株高、根长均有显著增长，且富营养化水体中的ＴＮ、ＮＨ４Ｎ、ＮＯ３Ｎ、ＴＰ、ＰＯ４Ｐ等的去除率可达８０％以上。通过应用人工基质无土栽培技术将一些陆上植物用于富营养化水体的治理工程中，同时具有环境效益和经济效益。对此方法的应用前景进行了讨论。
The purification of eutrophic water body was studied by means of soilless cultiv ation technique on artificial substratum. In lab test, three spices plants: Oen anthe decumbens,Lolium multiflorum and Ipomoea aquatica Forsk grew well an d the removing rates of TN,NH 4 N,NO 3 N,TP,PO 4 P were as high as 80%. Th e soilless cultivation technique on artificial substratum was studied in order t o purify the eutrophic water body and to get considerable economic benefit at th e same time. The application prospect of the means was discussed also.
