中文摘要 | 依照臺灣省漁業局烏山頭淡水養殖中心現有之循環水設施過濾池部分,製作直線比為10:1之模型,於實驗室內進行過濾池之操作研究。在不同流速及停留時間下,觀察水質改善之情形,其結果顯示在研究之流量範圍,過濾池對移除養殖水中之懸浮固形物有效,但若希望有機物之氧化及氮素硝化作用亦能進行以增進效果,則模型流量應低於126.6ml/min,即烏山頭現有設施流量應低於7m³/hr,水力停留時間應超過60分鐘。 |
英文摘要 | The efficiency of the gravel filter unit of the water recirculation system of Wushantow Freshwater Fish Culture Demonstration Center (WFFCDC), Taiwan Fisheries Bureau, was studied by using a model of linear ratio of 10:1. The study was carried out at various flow rates and retention time. From the results, the suspended solids of pond water could be removed sufficiently in the flow rate from 63.3 ml/min to 189.9 ml/min. But with the effective carbon oxidation and nitrification only occurred at the flow rate less than 126.6 ml/min, that is the corresponding flow rate less than 7m³/hr and retention time longer than 60 min are required for the gravel filter unit of the water recirculation system of WFFCDC to improve the water quality of effluent. |
