| 摘 要： | 鱼类代谢产物是养殖水体的主要污染源，但同时也是能被水生植物利用的高能、优质的营养物质（Ｎ和Ｐ）。该文研究了孔石莼对养鲍污水的静态净化过程，分析了孔石莼滤池中水质的变化规律。结果表明，孔石莼能同时吸收水中的三氮和磷酸盐，尤其对氨氮有极强的吸收作用，但对有机物的去除不明显。建立了静态条件下对氨氮的净化模型。用孔石莼净化养殖污水具有净水、节能和收获饵料的综合效果。

| Abstract: | Fish effluents are main pollutant in aquaculture system,these waste products are also high energy and high quality nutrients (N and P) and usable for seaweed.This paper studied the static purification of abalone effluents by Ulva P.K. The changes of water quality in Ulva tank were analysed.Results show that Ulva P.K. can uptake ammonia,nitrite,nitrate and phosphorus simultaneously.Ammonia removal is efficient,but the changes of COD is minimal.The decrease of ammonia in this system can be described by a model. Ulva P.K.can be used in intensive aquaculture system to clean water,save energy and provide an extra commercial crop. |
