摘要:
在实验室条件下.对伊乐藻及轮叶黑藻净化养鱼污水的能力进行了比较研究。结果表明:(1)伊乐藻和轮叶黑藻对养鱼污水中的N、P等物质有较好的净化效果。在96h内,它们对TN、TP、PO43--P、NH4+-N、NO3--N、CODMn的平均净化率分别为:60.7%,53.6%.74.4%.59.7%,75.1%,63.2%;61.8%,54.2%.85.3%,81.8%,31.4%,33.5%。(2)水生植物在净化过程中,其效率受温度、光照、及水体中营养盐浓度等外界条件的制约。(3)微生物在水生植物净化养鱼污水的过程中起着重要的作用。

Abstract:
The treatment effect of fishculture waste water by Eiodea nattalii and Hydrilla verticilla-ta undertaken in Laboratory is studied and compared.The results show as follows; (1) Eiodea nattalii and Hydrilla verticillata have strong capacity of purification on nitrogen and phosphorus, etc.in fishculture waste water.After 96 hours, treated with Eiodea nattalii, the average loss rate of toatl nitrogen, total phosphorus, amonia nitrogen, nitrate nitrogen and chemical oxygen demand is 60.7%, 53.6%, 74.4%, 59.7%, 75.1%, and 63.2%; while treated with Hydrilla verticillata, the average loss rate is 61.8%, 54.2%, 85.3%, 81.8%, 31.4% and 33.5%.(2) The purifiration capacity of the two macrophytes is restricted by water temperature, light and the content of nutrient.(3) Microbe plays an important role in the purifying proecss of fishculture waste water by the water plants.
