本研究旨在探討滾筒式粒子過濾機對與大型室內式循環水養殖系統水質的影響。實驗結果顯示，滾筒式粒子過濾機不只其有去除循環水中懸浮固形物的功能，亦對系統中生物濾床硝化作用有正面的影響。其懸浮固形物的平均去除率與平均去除效率分別為7.33 g/hr與12.05%。循環水系統中生物濾床對亞硝酸態氮的硝化作用，當有滾筒式粒子過濾機運轉時，生物濾床進、出水口之亞硝酸態氮濃度平均差異達到0.421 mg/l，遠高於無滾筒式粒子過濾機運轉時之平均濃度差異0.092 mg/l。本研究獲致滾筒式粒子過濾機之運轉對循環水養殖系統之水質改善具有實質上的貢獻。

In this research, the effect of the water quality by using a drum-type solid particle filter in a domestic developed indoor recirculating-water culture system is studied. The experimental results show that the drum-type solid particle filter does not only obtain a function of removing Suspended Solids (SS) from the recirculating-water, but also has a positive effect to the nitrification of the biofilter in the culture system. The average removing rate of the Suspended Solids and the average removing efficiency of the drum-type solid particle filter are 7.33 g/hr and 12.05%, respectively. By comparing the performance of nitrification of the biofilter, the avenge difference of Nitrite (NO2-N) concentration measured between the inlet and outlet is 0.421 mg/l as the drum-type solid particle filter running, which is higher than the value of 0.092 mg/l without the operating of the drum-type solid particle filter. This study gets the result of that the operating of a drum-type solid particle filter has a substantial contribution to the improvement of the water quality in a recirculating-water culture system.
