| 中文摘要 |
| 在缫丝工业排放废水的水体中, 无土栽培水蕹菜.经静态、动态和现场试验, 水蕹菜在去除废水有机污染物的过程中, 在较强的适应性.在6—7月间, 水蕹菜在667m2水面上10天的产量为625kg.应用水蕹菜无土栽培技术于缫丝废水资源化生态工程之中, 既可以净化污水, 又具有经济效益。认为该项技术可与黑麦草无土栽培技术衔接使用, 形成全年运转的配套植物净化污水的方法. |
| 英文摘要 |
| Ipomoea aquatica Forsk was cultivated on the surface of wastewater discharged from a filature mill. In the process of removal of organic materials from the wastewater, Ipomoea aquatica Forsk showed a pretty good adaptability to the wastewater in static, dynamic .and pilot experiments. 625 kg of Ipomoea aquatica Forsk could be gathered in ten days in an area of 667 m2 during the period of time from June to July in 1988. The results show that the application of the technique of soilless cultivation of Ipomoea aquaiica Forsk to ecological engineering of filature wastewater can not only purify wastewater, but also produce economic benefit. And it may be combined with the technique of soilless cultivation of loliurn, multiflorum lam so as to form a complete set of wastewater treating method by plants all the year round. |
